Size Calculations for Carnivorous Theropods.

My size calculations for theropod dinosaurs.

Update (9/11/19): All specimen sizes are up-to-date!

The Percentage Increase/Decrease Method:
1. Take new number and subtract it from original number.
2. Take that number and divide it by the original number and multiply by 100.
3. That number will by your percentage increase or decrease if it's negative.

Ex.: "Stan's" Femur is 130 and has a body length of 12.2 meters. "Wyrex" has a femur length of 132.7 cm.

132.7 - 130 = 2.7.
2.7 divided by (represented by "/") and multiplied by (represented by "*") equals 2.1.
(2.7/130*100 = 2.1)
2.1 is your percentage increase, or 2.1% increase.
12.2 m + 2.1% = 12.5 meters for "Wyrex."

Tyrannosaurus rex:
1. BHI 3033 ("Stan"):
I grew up with this specimen. Whenever I go to the Smithsonian Natural History Museum in Washington D.C, he's my favorite part of the exhibit.

I couldn't find a picture of "Stan's" femur to measure, so I'm going with the original femur length given:

 Femur (Original Size): 130.0 cm. (BHIGR)

Compared to MOR 555, with a femur that was 128 cm in length, "Stan" would be 12.2 meters long.

MOR 555's Measurements (Farlow et al., 1995):
Femur: 128 cm.
Body: 11.96 or 12.0 meters. (Farlow et al., 1995) (Natural Museums Scotland)

128 - 130 = 2.
2/128*100 = 1.6% increase.
12.0 m + 1.6% = 12.2 meters for "Stan."

(Update 8/27/19): MOR 555's femur is now 130 cm. This makes MOR 555 12.2 meters as well.

According to the Black Hills Institute's (BHIGR) website, "Stan" was 12.2 meters long with a 130-cm femur. Therefore, any T.rex with a 130-cm femur would be 12.2 meters long.

Note (8/4/19): I'm sticking with the 130-cm femur length because I did manage to find a picture of "Stan's" femur in Larson and Carpenter (2008) (pg. 121). However, I got 155 cm for it (straight side)! I know that's WAY too big for this specimen. Also, Larson and Carpenter (2008) gave "Stan's" femur a length of 131 cm (pg. 122), so 155 cm is just too big. Therefore, I'm sticking with the original femur length.

BHI 3033's Femur ("A") (Larson and Carpenter (2008) (pg. 121):
Update (9/5/19): I found a picture of "Stan's" skull in Carpenter (2013) (pg. 268) (Scale bar is 10 cm):
Measurement 1 (9/5/19):
*Maxilla: 76 cm.
*Dentary: 91 cm.
Skull: 142 cm.
Mandible: 126 cm (Measured on 3/21/21).

Measurement 2 (9/5/19):
*Maxilla: 76 cm.
Dentary: 90 cm.

Measurement 3 (9/5/19):
*Maxilla: 76 cm (at best).
Dentary: 90 cm.

AMNH 5027:
Dentary: 94 cm.
Body: 12.6 meters.

91 - 94 = 3.
3/91*100 = 3.3% increase.
12.2 m + 3.3% = 41 feet (12.6 meters).
147 cm + 3.3% = 151.9 cm for the skull.
12.6 m - 3.3% = 12.2 meters for "Stan."
91 - 94 = 3.
3/94*100 = 3.2% decrease.
12.6 m - 3.2% = 40 feet (12.2 meters) for "Stan."

Correction: 91 cm seems correct. Perhaps BHIGR really did meant that the full dentary really is 91 cm. This was also mention in the BHIGR Catalog (2012) (p. 2):
***Conclusion:
Maxilla: 76 cm (Measured in Carpenter, 2013, p. 268).
Dentary: 91 cm (Measured in Carpenter, 2013, pg. 268) (BHIGR) (BHIGR Catalog, 2012, p. 2).
Skull: 147 cm (Based on AMNH 5027) (BHIGR) (BHIGR Catalog, 2012, p. 2).
Body: 40 feet (12.2 meters) (BHIGR) (BHIGR Catalog, 2012, pg. 2).

BHI 3033's Total Length: 40 feet (12.2 meters).

Note: I also got 130 cm for "Stan's" femur from Paleofile. (Measured again on 12/27/19)

"Stan's" Stats:
Femur: 130.0 cm. (BHIGR) (Paleofile)

2. MOR 555 ("Wankel Rex"/"Nation's Rex"):
MOR 555's Femur Lengths:
1. Larson (1994) (pg. 142): 130 cm. (Same as "Stan")

2. Farlow et al., (1995) gave 128.0 cm for MOR's femur (pg. 715). They also gave it a body length of 12.0 meters. National Museums Scotland gave the same body length.

3. Theropod Database: 127.7 cm.

It seems that the original femur length for MOR 555 is 130 cm, just like "Stan's." Therefore, I'm going to give MOR 555 the same body length as "Stan."

MOR 555's Femur Length (Larson, 1994, pg. 142):
Also, Horner and Lessem (1993 gave MOR 555 a length of 40 feet on pg. 144. They also gave it a skull length of 5 feet. "Stan's" skull is 147 cm long, which is also 5 feet. Therefore, MOR 555 is 40 feet long (12.2 meters), with a skull length of 147 cm, and a femur length of 130 cm.

 Weight:
Horner and Lessem (1993) state that paleontologist Jim Farlow gave MOR 555 a weight of 6.5 tons (pg. 199). Farlow et al., (1995) gave MOR 555 a weight of 6000 kg, which is 6.6 tons. Dave Smith (1995) gave MOR 555 a weight of 6 tons, and a body length of 40 feet. Therefore, MOR 555 weighed about 6-6.6 tons.

The age of this specimens spans from 14-22 years (Horner and Padian, 2004) (Erickson et al., 2005) (Orf, 2014) (Hendrix, 2019) (National Museums Scotland). Horner and Padian (2014) used a cross-section of its tibia to guess its age at around 14 years old (pg. 1877). Horner in 2013 also said that the specimen is still growing (Schontzler, 2013). T.rex stops growing at around age 18 (Erickson et al., 2004, pg. 773) (Science Daily, 2004), so age 14 seems to be more accurate for MOR 555.

 MOR 555's Total Length: 40 feet (12.2 meters).
Age: 14 (Horner and Padian, 2004, pg. 1877).
Age 18: 44 feet (13.4 meters)(?) (My estimate).

Just to make sure that this specimen is really 40 feet long, or the same size as "Stan," I estimated the size of "Stan's" tibia based on his maxilla, and compared it to "Sue's":

86 - 76 = 10.
10/86*100 = 11.6% decrease.
124 - 11.6% = 109.6 cm for "Stan's" tibia.

This is extremely close to what Larson (1994) gave to MOR 555's tibia, which is 109 cm. I will gave the same length to MOR 555's tibia, but keep the 130-cm length for MOR 555's femur.

Update (3/21/21): Carr (2020) says that MOR 555's estimate of 14 years of age was based on a damaged bone, so the actual age of the animal is older (Materials and Methods: Chronological age data"). He gave the animal an age of 25 (Figure 12, number 23).

MOR 555's Stats:
Femur: 130.0 cm. (Larson, 1994, pg. 142)
Tibia: 109.6 cm.
Weight: 6-6.5 tons. (Horner and Lessem, 1993, pg. 199) (Farlow et al., 1995) (Dave Smith, 1995)
Age: 25. (Carr, 2020, Figure 12, number 23)

Fun Fact: I FINALLY saw this specimen at the museum on 8/17/19, and it was a magnificent sight!

Notes: 
-Currie and Carpenter (1999) says that "Stan" and "Wankel Rex" are the same size (pg. 208).

-NMNH says that "Stan" is 40 feet long and weighed 6 tons. "Wankel Rex" is also said to have weighed 6-6.5 tons, so this also seems to conclude that "Wankel Rex" is 40 feet long.

Update (6/30/20): A replica of MOR's skull has been created by Master Replicas. It measures 58 inches (147.3 cm) long (also noted on Amazon, "Product Information"). However, it has also been given a length of 60 inches (Toynk.com) (Amazon). However, Toynk.com and Amazon have stated that the skull was made by Master Replicas, so Master Replicas' length of 58 inches is the correct length.

Therefore, based on "Stan's" skull, MOR 555 is 12.2 meters long:
147 - 147.3 = 0.3.
0.3/147*100 = 0.2% increase.
12.2 m + 0.2% = 12.2 meters.

MOR 555's Stats:
Skull: 147.3 cm. (Master Replicas)
Femur: 130 cm. (Larson, 1994, pg. 142)
Tibia: 109.6 cm. (Also given a length of 109 cm in Larson, 1994, pg. 142)
Age: 25. (Carr, 2020, Figure 12, Number 23)

3. UWBM 99000 ("Tufts-Love Rex"):
The dentary is stated to be three feet long (Burke Museum, 12/1/2016):
Dentary:
Three feet is 91.4 cm.

The specimen is also said to have been 12.2 meters long (IFL Science, 2016) (Burke Museum, 8/17/2016), and the 91.4-cm length is consistent with "Stan's" 91-cm dentary.

"Stan":
Dentary: 91 cm.
Body: 12.2 meters.

91.4 - 91 = 0.4.
0.4/91*100 = 0.4% increase.
12.2 m + 0.4% = 12.3 meters.

It looks like this specimen was 40 feet after all. However, it was only 15 years old (IFL Science, 2016) (Burke Museum, 8/17/2016).

Age 18: 43 feet (13.1 meters)(?). (My Estimation)

UWBM 99000's Total Length: 40 feet (12.3 meters).
Age: 15.

5. AMNH 5027:
AMNH was given the same weight as CM 9380 (8.0 tons) (Snively et al., 2018), and Larson (1994) gave it the same ilium length as CM 9380, so it looks like they were the same size.

However, Dalman (2013) shows AMNH's and "Stan's" mandibles (jaws). It looks like AMNH was slightly bigger than "Stan."

AMNH 5027's and BHI 3033's Mandibles (Dalman, 2013):
Update (8/27/19): Skull (Cast) (WitmerLab Dinosaur Skull Collection):
Dentary: 96.5 cm. (At best) (Measured on 9/4/19)
Update (3/13/21):
Dentary: 87.5 cm (at best).
Maxilla: *74.4 or 78.5 cm (at best).

BHI 3033:
Dentary (Complete): 91 cm.
Skull: 147.0 cm.
Length: 40 feet (12.2 meters).

96.5 - 91 = 5.5.
5.5/91*100 = 6% increase.
12.2 m + 6% = 42 feet (12.9 meters).

Update (9/5/19): Skull picture from Carr and Williamson (2004) (Figure 19):
(Assuming the scale bar is 20 cm):
Maxilla: 78 cm.
Dentary: 93 cm.
Skull: 151 cm. (I got it one other time but I disregarded it)

If scale bar is 10 cm only, then the maxilla would have been 38 cm. That doesn't seem right. 78 cm sounds better.

"Stan":
Maxilla: 76 cm.
Dentary: 91 cm.
Skull: 147 cm.
Body: 12.2 meters.

Maxilla:
78 - 76 = 2.
2/76*100 = 2.6% increase.
12.2 m + 2.6% = 12.5 meters.

Update (3/13/21): Right Dentary (Cast) (WitmerLab Dinosaur Skull Collection) (Also used in Dalman, 2013) (Scale bar is 9 cm):
Length: 94 cm (at best) (got it twice).

"Stan":
Maxilla: 76 cm.
Dentary: 91 cm.
Skull: 147 cm.

91 - 94.5 = 3.
3/91*100 = 3.3% increase.
12.2 m + 3.9% = 41 feet (12.6 meters).
147 cm + 3.9% = 151.9 cm for the skull.

I guess AMNH 5027 is slightly bigger than "Stan" after all.

AMNH 5027's Total Length: 41 feet (12.6 meters).

AMNH 5027's Stats:
Dentary: 94 cm.
Skull: 151.9 cm.
Age: 21-23. (Erickson et al., 2006, pg. 14) (Carr, 2020, Figure 12, Number 17)

8. CM 9380/AMNH 973 (Holotype):
Femur: 130 cm. (Osborn, 1906) (Larson, 1994) (Paul, 1998, pg. 261)

"Stan" has the same femur length, so it looks like the holotype was 12.2 meters long.

Update (8/3/19): I was able to find a measurement of CM's femur in Weishampel et al., (2004):
Femur (Straight Side/Total Length): 136 cm. (Measured in Weishampel et al., 2004, pg. 126, "A," Cranial View) (Measured on 9/4/19 and 9/6/19)

Note: That is CM 9380's/AMNH 973's femur in Osborn (1917).

CM 9380's Femur (Osborn, 1917):
"Hank":
Femur: 133.4 cm.
Body: 12.6 meters.

136 - 133.4 = 2.6.
2.6/133.4*100 = 2% increase.
12.6 m + 2% = 42 feet (12.9 meters).

Maxilla from Hendrickx and Mateus (2014) (Figure 2) (Scale bar is 5 cm):
Length: 78.5 cm (also got it for B) (Measured on 3/18/21).

"Tristian Otto":
Maxilla: 77 cm.
Body: 12.4 meters.

77 - 78.5 = 1.5.
1.5/77*100 = 2% increase.
12.4 m + 2% =  42 feet (12.7 meters).

It looks like the holotype was 42 feet long wither way. I had no idea that this specimen was THAT big. I'll go with the femur length.

CM 9380's Total Length: 42 feet (12.9 meters).

CM 9380's Stats:
Femur: 136 cm.
Maxilla: 78.5 cm.
Age: 22-26. (Erickson et al., 2006, pg. 14) (Carr, 2020, Figure 12, Number 25)

9. CM 79057 ("Samson"/"Z-Rex"):
This specimen was used to help create the bull T.rex in The Lost World Jurassic Park (Todd Ackerman, 1997). Despite its name, "Samson" was a female.

Larson and Carpenter (2008) and the Theropod Database give a femur length of 1.295 meters for "Samson's" femur, but the Theropod Database stated that Glut (2002) gave a femur length of 1.36 meters. This means that "Samson's' original femur length is 136 cm. I couldn't find a picture of the femur to measure myself, so I'll go with the original length.

Glut (2002) from the Theropod Database:
Picture 2:
Femur: 1.36 meters. (Glut, 2002; stated on the Theropod Database website)

Theropod Database also gave "Samson" a length of 12.6 meters and "Sue" 12.8 meters.

"Hank":
Femur: 133.4 cm.
Body: 12.6 meters.

136 - 133.4 = 2.6.
2.6/133.4*100 = 2% increase.
12.6 m + 2% = 12.9 meters.

It looks like "Samson" actually was one foot shorter than "Sue" after all.

"Samson's"/"Z-Rex's" Total Length: 42 feet (12.9 meters).
Femur: 1.36 meters. (Glut, 2002; stated on the Theropod Database website)

10. LACM 23844:
Left Dentary (Slightly incomplete) (Molnar, 1991, Plate 12) (Scale bar is 10 cm):
2 (Lateral View):
Length:
-97 cm.
-99.5 cm (at best) (Remeasured on 3/21/21).
Dentary Tooth Row: 57 cm (at maximum).
*1 (Medial View):
Length: 101 cm (at best).
Dentary Tooth Row: 58 cm (at best).

Dentary seems to be incomplete on the "posteroventral angle" (pp. 154-155). The tooth row seems to support this on the medial side.

Dentary Length (Lateral View):
AMNH 5027:
Dentary: 94 cm.
Body: 12.6 meters.

99.5 - 94 = 5.5.
5.5/94*100 = 5.9% increase.
12.6 m + 5.9% = 44 feet (13.3 meters).

"Stan":
Dentary: 91 cm.
Body: 12.2 meters.

99.5 - 91 = 8.5.
8.5/91*100 = 9.3% increase.
12.2 m + 9.3% = 44 feet (13.3 meters).

Dentary Length (Medial):
Based on "Sue": 13.6 meters.

Dentary Tooth Row (Lateral View):
"Scotty":
Dentary Tooth Row: 57.3 cm.
Body: 14.1 m.

57 - 57.3 = 0.3.
0.3/57.3*100. = 0.5% decrease.
14.1 m - 0.5% = 46 feet (14.0 meters).

Dentary Tooth Row (Medial):
Based on MOR 980: 47 feet (14.3 meters).

Notes: 
-Gignac and Erickson (2017) gave LACM the largest skull length (136.5 cm) compared to "Sue" (127.5 cm) (Table 1).

-Carr (2020) gave LACM the same skull length (premaxilla-quadrate) as "Sue" and MOR 008 (140 cm) (Materials and Methods: Size, para. 1; Table 15).

LACM 23844's Total Length: 47 feet (14.3 meters).
Dentary (Incomplete): 101 cm (medial).
Dentary Tooth Row: 58 cm (medial).


11. FMNH 2081/BHI 2033 ("Sue"):
The largest, most complete specimen of T. rex. However, just how large is she (If it's really a "she")?

Right Femur (Measured on 9/4-8/19):
Straight Side: 137.0 cm. (Surprisingly, the 137-cm length was stated in "A Tyrannosaurus Rex Named Sue," 2001)
Short side with femoral head: 135 cm.
Total Length (From femoral head to tip of longest side): 143 cm (at best). (Measured on 9/8/19 and 10/23/19)

Originally, her femur was listed as 138.0 cm (Larson, 1994, pg. 142) (Mazzetta et al., 2004). However, her femur was just stated as being 54 cm most of the time (BHIGR) (WMNH). 137.0 cm is 54 cm, and I measured it myself, so I'll go with my size estimate.

"Sue's" Right Femur (Brochu, 2003, pg. 112, "A," Posterior View). (Scale bar is 30 cm):
Now, let's see how large "Sue" is:

CM 9380 and "Samson/Z-Rex":
Femurs: 136 cm.
Bodies: 12.9 meters.

137 - 136 = 1.
1/136*100 = 0.7% increase.
12.9 m + 0.7% = 13.0 meters.

Update (9/8/19): Let's see how big she is with her total femur length:

136 - 143 = 7.
7/136*100 = 5.2% increase.
12.9 m + 5.2% = 45 feet (13.6 meters).

This sounds crazy, but "Sue' has been given 45 feet before (links down below).

Note (5/16/20): I decided to compare "Sue's" humerus to "Hank's," and see what I'd get.

"Hank":
Humerus: 35.6 cm.
Length: 12.6 meters.

"Sue":
Humerus: 39 cm. (Measured in Brochu, 2003, pg. 97, right humerus, "A," Dorsal). (This length was also stated in Larson, 1994 and Larson and Carpenter, 2008)

39 - 35.6 = 3.4.
3.4/35.6*100 = 9.6% increase.
12.6 m + 9.6% = 45 feet (13.8 meters).

So either way, "Sue" is 45 feet long, but I'll go with the femur length.

My Skull Size Estimate:
LACM 23844:
Dentary: 97 cm.
Skull: 156.8 cm.
Body: 13.0 meters.

97 - 101 = 4.
4/97*100 = 4.1% increase.
156.8 cm + 4.1% = 163.2 cm.

FMNH 2081/BHI 2033's Total Length: 45 feet (13.6 meters).
Femur: 143 cm.
Weight: 9.3 tons. (Persons IV et al., 2019)

"Sue's" Stats:
Right Dentary: 101.0 cm. (Measured in Brochu, 2003, pg. 41, "C") (I got it twice on 8/20/19 and 8/21/19)
Right Dentary Tooth Row: 56 cm. (Measured in Brochu, 2003, pg. 41, right dentary, D medial and C lateral)
Right Mandible (Jaw): 140.0 cm. (Measured in Brochu, 2003, pg. 41, right jaw, "C") (8/20/19)
Right Maxilla: 86 cm. (Measured on 9/4/19 in Brochu, 2003, pg. 8, "A," Lateral View):
Right Femur (Measured on 9/4-8/19 in Brochu, 2003, pg. 112, "A," Posterior):
Straight Side: 137 cm. (4th time) (Also stated in "A Tyrannosaurus Rex Named Sue," 2001)
Short side with femoral head: 135 cm.
Total Length (From femoral head to tip of longest side): 143 cm (at best). (Measured on 9/8/19 and 10/23/19)
Right Femur Width: 20 cm. (Measured in Brochu, 2003, pg. 112, "A")
Left Femur (Measured on 9/4/19 in Brochu, 2003, pg. 112, "E," Posterior):
Straight Side/Total Length: 132 cm.
Skull:
-Right Side: 153 cm. (Measured on 9/4/19 in Brochu, 2003, pg. 12, "A") (Same as Larson, 1994) (Left size of skull is crushed [Brochu, 2003, pg. 6]).
-Based on dentary compared to LACM 23844: 163.2 meters.
Left Squamosal: 44 cm. (Measured in Brochu, 2003, pg. 28, "B," Lateral)
Humerus:
Length: 39.0 cm.
Width (Large End): 14 cm wide.
(Both were measured in Brochu, 2003, pg. 97, right humerus, "A," Dorsal) (Also in Larson, 1994 and Larson and Carpenter, 2008)
Pedal Phalanx IV-2: 14.0 cm. (Measured in Brochu, 2003, pg. 123)
Pedal Phalanx II-2: 16.0 cm. (Measured in Brochu, 2003, pg. 123)
Pedal Phalanx III-2: 16 cm. (Measured in Brochu, 2003, pg. 123)
Right Pedal Phalanx IV-1: 16.0 cm. (Measured in Brochu, 2003, pg. 123)
Right Tibia: 124 cm. (Measured on 9/24/19 in Brochu, 2003, pg. 114, "A," Medial)
Right Fibula: 110 cm. (Measured twice on 9/24/19 in Brochu, 2003, pg. 116, "C," Lateral)
Ilium (Right): 165 cm (at best) (Measured on 5/20/22 in Brochu, 2003, p. 105 Figure 90).
Weight: 9.3 tons (8,460 kg) (Persons IV et al., 2019)

12. RGM 792.000 ("Trix"):
I've noticed that "Trix" has been given the same measurements that "Sue" has:

"Sue":
Body Length: 12.5/13.0 ("Larson, 1994") (Ibrahim et al., 2014) to 13.0 meters (Brusatte et al., 2010) (Gignac and Erickson, 2017) (Reuters, 2017)
Skull: 1.50 meters. ("A Tyrannosaurus Rex Named Sue," 2001) (Field Museum, 2008)

"Trix":
Body Length: 12.5/13.0 (Business Wire, 2016) to 13.0 meters (Daily Mail, 2016).
Skull: 1.50 (Reims et al., 2016) to 2.0 meters. (TCT Magazine, 2017)

I think "Trix's" skull is the same length as 'Sue's," making her real body length 42 feet (12.8/13.0 meters) instead of 12.5 meters. Therefore, "Trix" and "Sue" were the same size.

Update (8/23/19): I've FINALLY found some of "Trix's" bones to measure!

Skull: 152.4 cm (60 inches) (Not including the partial dentary). (Measured on 8/25/19)
Trix's Tibia:
Length: 119.5 cm. (Measured on 5/10/20).

"Sue":
Maxilla: 86 cm.
Skull: 163.2 cm.
Tibia: 124 cm.
Body: 13.6 meters.

Tibia:
119.5 - 124 = 4.5.
4.5/124*100 = 3.6% decrease.
13.6 m - 3.6% = 43 feet (13.1 meters).

Skull:
83.8 - 86 = 2.2.
2.2/86*100 = 2.6% decrease.
163.2 cm - 2.6% = 159 cm.

"Trix's" Total Length: 43 feet (13.1 meters).
Tibia: 119.5 cm.
Skull (Complete): 159 cm.
Maxilla: 83 cm.

13. MOR 980 ("Peck's Rex," "Rigby Rex," "T.rex imperator"):
I had a hard time trying to come up with an accurate size for this specimen. It always seemed to be neck-and-neck with "Sue." When "Sue" was given 12.5/13.0 meters in length (Larson, 1994, pg. 142), MOR 980 was 12.4 meters long (DinoCasts.com). Then it was given 12.8/13.0 meters, along with "Sue" (Theropod Database). Then it was given 12.3 meters, alongside "Sue" (Deak and McKenzie, 2016) (Siebel Dinosaur Complex). Then paleontologist Peter Makovicky stated that both it, "Sue," and "Scotty" had the same femur widths (Chicago Tribune, 2019).

I tried to find a bone to measure MOR 980 against other T.rex specimens, but it was not easy. Here's what I got:

Humerus: 36.2 cm. (Larson and Carpenter, 2008)

Dentary:
*Dentary Tooth Row: 58.0 cm (lateral view).
Note: "Sue's" is 56 cm (my measurement from Brochu, 2003, pg. 41, right dentary, D medial and C lateral).

"Sue":
Dentary Tooth Row: 56 cm (medial and lateral).
Body: 13.6 m.

58 - 56 = 2.
2/56*100 = 3.6% increase.
13.6 m + 3.6% = 46 feet (14.1 meters).

"Scotty":
Dentary Tooth Row (my measurement): 57.3 cm (medial).
Body: 14.1 meters.

Based on "Sue," tooth row length is usually the same in both lateral and medial views.

57.3 - 58 = 0.7.
0.7/57.3*100 = 1.2% increase.
14.1 m + 1.2% = 47 feet (14.3 meters).

*Pubes:
CM 9380: 1.25 meters. (Osborn, 1905) (Theropod Database)

132.0 - 125.0 = 7% increase.
12.2 m + 7% = 13.1 meters for MOR 980.

The only accurate bone that I can measure for this specimen are its pubes. Therefore, I'll go with that length.

Extra Notes:
Gignac and Erickson (2017) gave MOR 980 a longer skull length (128.2 cm) than "Sue" (127.5 cm).

Update (8/26/19): I was able to come up with two measurements for MOR 980's humerus and incomplete dentary that I showed above:

Humerus (Cast In Black):
Length: 36.4 cm. (RMDRC paleo lab) (8/26/19)
Width: 11.5 cm. (RMDRC paleo lab) (8/26/19)

Dentary:
Incomplete Length: 85 cm.
My Estimated Complete Dentary Length: 98.5 cm. (I had to draw what I thought the missing portion of the dentary looked like)

Update (9/2/19): 
MOR 980:
Humerus: 36.4 cm.
*(?)Dentary: 98.5 cm. (My estimated total length)
(?)Body: 42 feet:
12.9 m (Compared to "Hank's" humerus)
*12.7 m (Compared to "Sue's" dentary)

Update 9/7/19: So after I got the 12.9-meter estimate for CM 9380, I remembered this picture I found of CM 9380's and MOR 980's skeletons:

MOR 980 (Left) and CM 9380 (Right):
Judging from this picture, MOR 980 would have to be the same size as "Sue" AT LEAST! Judging by this picture, it would have to have been a foot taller (and longer?) than CM 9380. Also, Gignac and Erickson (2017) gave MOR 980 a longer skull length (128.5 cm) than "Sue" (127.5). This would make MOR 980 0.8% longer than "Sue."

Also, Paleontologist Peter Makovicky said that MOR 980 has about the same femur width as "Sue" as well (Johnson, 2019). This means that MOR 980 would have weighed about the same as "Sue."

However, I want to have some kind of bone to measure. I don't really trust the "complete dentary length" that I gave earlier, so I'm going back to a nagging pain that's been stuck in my head for a long time now: the pubic bone length.

Pubis length:
1. 52 inches (132 cm) ("At least"). (Science Daily, 1997) (Los Angeles Times, 1997) (Theropod Database)
2. 52.4 inches (133 cm). (Mike Taylor, 2003) (Barnes-Svarney and Svarney, 1999/2010, p. 134) (Ebrary.net, 2014).

Since there are more (and recent) sources claiming the 133-cm length, I'll go with that length.

"Sue":
Pubis: 132 cm. (Measured on 9/7/19 in Brochu, 2003, pg. 106) (I got it three times)
Body: 13.6 meters.

133 - 132 = 1.
1/132*100 = 0.8% increase.
13.6 m + 0.8% = 45 feet (13.7 meters).

Welp, just like the skull length provided by Gignac and Erickson (2017), MOR 980 seems to have been 0.8% longer than "Sue..."

I've been trying my HARDEST to get a size estimate for this specimen, and I always come back to using its pubic bone length. I have to honestly come to the conclusion that perhaps MOR 980 was slightly longer than "Sue..."

One of the (perhaps) largest Mapusaurus specimen had a pubic bone shaft about 10% larger than the Giganotosaurus holotype specimen MUCPv-Ch 1's (Coria and Currie, 2006, pg. 101). That would make that Mapusaurus specimen 43 feet long (13.2 meters). Therefore, if that Mapusaurus specimen is considered to be that big based on its pubic bone shaft alone, then why not MOR 980?

I've been trying to slim down MOR 980, but then I remembered something: "Scotty" was once considered to have been smaller than "Sue," but now we know that she was bigger. Therefore, perhaps it's time to consider that maybe MOR 980 was also slightly longer than "Sue." However, "Sue" is clearly heavier than MOR 980.

Update (3/19/21): The dentary tooth row length might make MOR 980 even bigger, but I'll stick to the pubic length for now.

MOR 980's Total Length: 45-47 feet (13.7-14.3 meters).
Pubis Length: 133 cm.
Dentary Tooth Row: 58 cm.

MOR 980's States:
Length: 45-47 feet (13.7-14.3 meters).
Pubis: 133 cm.
Dentary Tooth Row: 58 cm.
Age: 21-25. (Erickson et al., 2006, pg. 13) (Carr, 2020, Figure 12, Number 22)

14. RSM 2523.8 ("Scotty"):
It's become kind of difficult to find an accurate size for this "Scotty," as of late. Originally, I gave her 40 feet (12.1 meters), based on her femur length, but it was kind of difficult to get an accurate length. This was due to how the photo of the femur was taken. Then I used her dentary (from Thomas Carr's blog), and I got 12.8/13.0 meters for "Scotty." Then it turns out that "Scotty" was way bigger than previously estimated.

A new paper came out examining her bones (Persons IV et al., 2019), giving more pre use estimates of her bones. Persons IV et al., (2019) gave her femur a length of 133.0-133.3 meters, compared to "Sue's" 132.1-cm femur from Brochu (2003). Unfortunately, I couldn't get an accurate estimate of the femur, so I looked at her dentary and right pedal phalanx IV-1.

"Scotty's" and "Sue's" Measurements (Persons IV et al., 2019):
"Scotty":
Right Pedal Phalanx IV-1:
18.4 cm. (Persons IV et al., 2019)
My Length: 23.5 cm (at best). (Measured on 9/24/19)
Dentary Tooth Row:
59.5 cm. (Persons IV et al., 2019)
My Length (Right Dentary): 57 cm. (Persons IV et al., 2019, right dentary, "B", medial)
Femur Width: 21.0 cm. (Persons IV et al., 2019) (The Guardian, 2019 reports a width of 20.3 cm)
Right Fibula: 120 cm. (Measured twice in Persons IV et al., 2019)

"Scotty's" Dentaries (I measured from the tip of the jaw to the 14th-marked alveoli):
"Scotty's" Right Fibula ("C") (All scale bars are 10 cm):
"Sue":
Right Pedal Phalanx IV-1: 16 cm (my measurement from Brochu, 2003).
Dentary Tooth Row:
58.5 cm. (Persons IV et al., 2019)
My Length (Right Dentary): 56 cm (Brochu, 2003, pg. 41, right dentary, "D," medial)
Femur Width: 20 cm. (Brochu, 2003, pg. 112, "A")
Fibula Length: 110.0 cm.

Update (8/23/19): "Scotty" is larger than I thought! I had some trouble trying to get a length of her femur, but I've FINALLY found a good pick of her femur that gave me an accurate length. It's longer than 138 cm...

Femur (Cast) from the Royal Saskatchewan Museum's Twitter Page:
(I measured the top picture, not the drawing)

Lengths: 
140 cm (Straight side).
142.5 cm (Other side with femoral head).
148.5 cm (Total length from femoral head to tip of longest end). (Measured on 9/8/19)

I'm going to go with the 140-cm length.

"Sue":
Femur: 137 cm.
Body: 13.0 meters.

140 - 137 = 3.
3/137*100 = 2.2% increase.
13.0 m + 2.2% = 13.3 meters.

Update (9/8/19): I've decided to go with the total femur length.

"Sue":
Femur (Total Length): 143 cm.
Fibula: 110 cm.
Body: 13.6 meters.

Femur:
148.5 - 143 = 5.5.
5.5/143*100 = 3.9% increase.
13.6 m + 3.9% = 47 feet (14.1 meters).

Fibula:
120 - 110 = 10.
10/110*100 = 9.1% increase.
13.6 m + 9.1% = 49 feet (14.8 meters).

Just to be safe, I'll go with the femur length.

RSM 2523.8's Total Length: 47 feet (14.1 meters).
Femur Length: 148.5 cm.
Right Fibula: 120 cm. 
Right Pedal Phalanx IV-1: 23.5 cm (at best) (My measurement).
Weight: 9.7 tons.

Length: 48.3 cm (19 inches at best) (incomplete).

"Sue":
Humerus: 39 cm.
Body: 13.6 meters.

48.3 - 39 = 9.3.
9.3/39*100 = 23.9% increase.

16. Bonhams #1023 or Lot 1148:
Length: 24 inches (60.96 or 61 cm).
Width (Large End): 17.8 cm (7 inches).

"Hank":
Humerus: 35.6 cm.
Body: 12.6 meters.

61 - 35.6 = 25.4.
25.4/35.6*100 = 71.4% increase.
12.6 m + 71.4% = 71 feet (21.6 meters).

"Sue":
Humerus:
Length: 39.0 cm.
Width (Large End): 14 cm.
Body: 13.6 meters.
Weight: 9.3 tons.

61 - 39.0 = 22.
22/39*100 = 56.4% increase.
13.6 m + 56.4% = 70 feet (21.3 meters).

Now, according to the Bonhams website, this is a T.rex humerus. However, it's extremely long. I don't know if this is actually a T.rex humerus or a misidentified bone to another dinosaur, but Bonhams says that it belongs to a T.rex. I was also thinking that the bone was given a huge length by mistake. However, Bonhams gave an accurate length for "Stan's" skull (1.47 meters), so then the size of the humerus might not be a mistake.

I also compared it to "Jane's" humerus. "Jane" is a juvenile T.rex, so maybe the humerus belonged to a youngster. Perhaps T.rex humerus' shrunk as they matured. However, "Jane's" humerus was 28 cm long (Theropod Database), so it looks like this humerus belonged to an adult T.rex. Based on its size, this specimen would have been 70 feet long (21.3 meters), based on "Sue." This might be the largest specimen of T.rex ever! What's even better is that this is a humerus, not a toe bone. This size estimate is more plausible than measuring a toe bone.

We can even measure this specimen agains a "12.3-meter" "Sue":
61 - 39.0 = 22.
22/39*100 = 56.4% increase.
13.3 m + 56.4% = 63 feet (19.2 meters).

Either way, this specimen was GINORMOUS!

Bonhams #1023's Total Length: 70 feet (21.3 meters).

Acrocanthosaurus' Total Length: 34-39 feet (10.2-12.0 meters).

Carcharodontosaurus:
1. UCRC PV12 (Originally SGN Din-1) (Neotype):
SGM-Din 1's skull is 1.60 meters (Sereno et al., 1996).

Giganotosaurus holotype MUCPv-Ch 1's skull was also given 1.60 meters (Coria and Currie, 2002). Therefore, they're the same size. I gave MUCPv-Ch 1 a length of 12.0 meters, so I'll give it to SGN-Din 1 as well.

SGM-Din 1's Total Size: 39 feet (12.0 meters).
Skull Size: 144.8 cm. (Based on MUCPv-Ch 1)
Maxilla: 47.0 cm. (Brusatte, 2007, pg. 905)

Mickey Mortimer from the Theropod Database gave a length of 1.42 meters for SGM-Din 1's skull, so my estimate for its skull is not entirely off.
Note: Eddy and Clarke (2011) also show that NCSM and Carcharodontosaurus specimen SGN-Din 1 basically had the same maxilla length (47.0 cm, given by Brusatte and Sereno, 2007).

Acrocanthosaurus specimen NCSM's Maxilla ("B") and Carcharodontosaurus specimen SGN-Din 1 ("C") (Eddy and Clarke, 2011, Figure 35):
Update (1/14/20): I wanted to have more evidence to calculate an exact length for this specimen, and I think I was able to find it:

Acrocanthosaurus NCSM 14345's Maxilla:
Beginning of Maxilla up to Beginning of AOF (Antorbital Fossa):
-*34 cm. (Measured on 1/14/20 in Canale et al., 2014, Figure 3, Lateral View) (Right maxilla?)
-33 cm. (Measured on 1/14/20 in Currie and Carpenter, 1999, pg. 211, Figure 3, Left Lateral View)
-32 cm. (Measured on 1/14/20 in Eddy and Clarke, 2011, Medial View)

Carcharodontosaurus saharicus SGM-Din 1's Maxilla:
Beginning of Maxilla up to Beginning of ANTFO (Antorbital Fossa):
-46 cm. (Measured on 1/14/20 in Brusatte, 2007, pg. 903, Figure 2, Lateral View)
-44 cm (at best). (Measured on 1/14/20 in Paleofile)
-38 cm. (Measured on 1/14/20 in Eddy and Clarke, 2011, "C," "Medial View)

I'm going with the measurement from Canale et al., (2014) for Acrocanthosaurus, and Brusatte (2007) for Carcharodontosaurus.

Acrocanthosaurus Specimen NCSM 14345:
Beginning of Maxilla up to Beginning of Antorbital Fossa (Lateral View): 34 cm. (Canale et al., 2014, Figure 3, Lateral View; Right maxilla?)
Length: 12.0 meters.

SGN-Din 1:
Beginning of Maxilla up to Beginning of Antorbital Fossa (Lateral View): 46 cm. (Brusatte, 2007, pg. 903, Figure 2, Lateral View)

34 - 46 = 12.
12/34*100 = 35.3% increase.
12.0 m + 35.3% = 53 feet (16.2 meters).

Update (10/23/20): UCRC PV12 (Originally SGN Din-1):
Maxilla from Ibrahim et al., (2020) (Figure 133). Scale bar is 20 cm:
Maxilla (from beginning to antorbital fossa): 41.5 cm. (I got it twice on 4/26/20 and once on 11/6/20; "A," Lateral View)
Tooth row from beginning of maxillary fenestra ("mf"): 30 cm (Measured on 10/23/20, "A").
*Tooth row from tip up to 8th tooth: 47.6 cm (at best) (Measured on 3/27/21, A, lateral view).

Acrocanthosaurus Specimen NCSM 14345:
Beginning of Maxilla up to Beginning of Antorbital Fossa (Lateral View): 34 cm. (Canale et al., 2014, Figure 3, Lateral View; Right maxilla?)
Length: 12.0 meters.

34 - 41.5 = 7.5.
7.5/34*100 = 22.1% increase.
12.0 m + 22.1% = 48 feet (14.7 meters).

Update (3/15/21): I compared the measurements I've obtained from Sereno et al., (1996) to Ibrahim et al., (2020)(a). All measurements were taken on Measured on 3/14/21.

UCRC PV12 (formerly SGN Din-1) from Sereno et al., (1996) (p. 988 Figure 2) (Scale bar is 50 cm):
UCRC PV12 Skeletal Diagram (with other specimens scaled to same size) from Ibrahim et al., (2020)(a), Figure 139) (Scale bar is 1 m):

Maxilla:
2020: 100 cm.
1996 (A): 102.5 cm.

*Skull:
*2020: 153 cm (at best) (Got it again on 3/27/21).
1996 (A): 164.5 cm (abt best).

Dentary (Ibrahim, 2020) (Scaled upward from another specimen): 110 cm (at best).

Acrocanthosaurus NCSM 14345:
Maxilla: 84 cm (at best).
Dentary: 85.5 cm (at best).
Skull: 144.4 cm.
Body: 12.0 m.

*2020 Skull Length:
144.4 - 153 = 8.6.
8.6/144.4*100 = 6% increase.
12.0 m + 6% = 42 feet (12.7 meters).

2020 Maxilla Length:
84 - 100 = 16.
16/84*100 = 19.1% increase.
12.0 m + 19.1% = 47 feet (14.3 meters). 

Dentary:
85.5 - 110 = 24.5.
24.5/85.5*100 = 28.7% increase.
12.0 m + 28.5% = 51 feet (15.4 meters).

Giganotosaurus Holotype MUCPv-Ch 1:
Skull: 149.8 cm.
Body: 12.4 meters.

*2020 Skull Length:
149.8 - 153 = 3.2.
3.2/149.8*100 = 2.1% increase.
12.4 m + 2.1% = 12.7 m.

1996 Skull Length:
Giganotosaurus Specimen MUCPv-95:
Skull: 157.9 cm.
Body: 13.1 m.

164.5 - 157.9 = 6.6.
6.6/157.9*100 = 4.2% increase.
13.1 m + 4.2% = 45 feet (13.7 meters).

Dentary:
Tyrannotitan Paratype:
Dentary: 90.5 cm (at best).
Body: 12.9 meters.

90.5 - 110 = 19.5.
19.5/90.5*100 = 21.6% increase.
12.9 m + 21.6% = 52 feet (15.7 meters).

For some reason, the total skull length gives a smaller, and more consistent, body estimate than the maxilla and dentary lengths. The maxilla for the specimen is very incomplete, so perhaps using it is not wise. Carrano et al., (2012) have stated state Carch.'s skull is actually only slightly larger than T. rex's (142 cm to 139 cm) (p. 225). I will go with Ibrahim et al., (2020)'s length, since it is more updated.

Update (3/27/21): After trying to be more accurate with my size estimates, I've come to the conclusion that tooth row length can help extrapolate a size estimate when it comes to dealing with fragmentary skull, and jaw, bones. 

UCRC PV12 (Originally SGN Din-1):
Maxillary tooth row from tip to 8th tooth: 47.6 cm.

Acrocanthosaurus NCSM 14345:
Maxilla: 84 cm (at best).
Tooth row from tip to 8th tooth: 41.5 cm.
Skull: 144.4 cm.
Body: 12.0 m.

47.6 - 41.5 = 6.1.
6.1/41.5*100 = 14.7% increase.
12.0 m + 14.7% = 45 feet (13.8 meters).
84 cm + 14.7% = 96.4 cm for complete maxilla.
144.4 cm + 14.7% = 165.6 cm for skull (Correlates well with what Carrano et al., 2012 said on p. 225. My skull length for "Sue" is 163.2 cm).

UCRC PV12's (SGM-Din 1's) Total Length: 45 feet (13.8 meters).
Skull: 165.6 cm.

3. MCF-PVPH-108.202:
MCF-PVPH-108.202 is said to have been either 29 feet (8.8/9.0 meters) (Coria and Currie, 2006, pg. 116) or 41 feet (NBC, 2006). Currie on NBC News in 2006 said that the largest individual of Mapusaurus discovered was 41 feet long, and MCF-PVPH-108.202 seems to be the largest individual based on how large its fibula is.

Coria and Currie (2006) stated that MCF-PVPH-108.202, represented by a fibula, is 2.5 cm longer than the Giganotosaurus holotype's, which is 83.5 cm long (Coria and Currie, 2006, pg. 104) (Theropod Database).

However, I decided to measure the fibula myself.

MCF-PVPH-108.202's Fibula (Scale bar is 10 cm):
Length: 104 cm. (Measured around 9/1-4/2019 in Coria and Currie, 2006, "B," Lateral View)

Tyrannotitan Paratype MPEF -PV 1157 (Largest Specimen):
Fibula: 88 cm.
Body: 12.9 meters.

104 - 88 = 16.
16/88*100 = 18.2% increase.
12.9 m + 18.2% = 50 feet (15.3 meters).
Note: Carcharodontosaurs had small fibulas and tibias compared to their femurs.

It looks like this is the largest specimen after all. Originally, I always thought that Mapusaurus was smaller than Giganotosaurus, but it seems that Mapusaurus (up to 15.3 meters) was longer than Giganotosaurus (up to 12.7 meters).

Originally, this specimen was given a length of 10.2 meters, which is the largest size of the specimens listed in Coria and Currie (2006) (pg. 116). However, the femur length wasn't stated in the paper, so I decided to measure it myself.

Femur (Coria and Currie, 2006, pg. 101, "A," Anterior) (Scale bar is 10 cm):

Minimum shaft dimensions (length and width, it seems) are 10% greater than in the holotype of Giganotosaurus (Coria and Currie, 2006, pg. 101).

There isn't a picture of the pubic shaft in the paper, so I guess the only way I can get a measurement for this specimen is to add 10% to 12.4 meters.

"Saurophaganax":
(Illustration is owned by me)

Update (11/17/24):
Saurophaganax is mostly a chimera, and the holotype and axial (vertebral) material probably belong to a sauropod (Danison et al., 2004). I will wait until further notice, but "Saurophaganax" probably doesn't exist anymore.

Size speculation: 14 meters. (Chure, 1995, pg. 105)

1. OMNH 01370:
Tibia: 101 cm. (Measured in Chure, 1995, pg. 105, Medial View)
Allosaurus tendagurensis Holotype MB.R3620:
Tibia: 91 cm. 
Body: 10.0 meters.

Saurophaganax's Total Length: 28-36 feet (8.4-11.1 meters).

 Notes:
-Paleontologist Andrea Cau (2009) suggests that Saurophaganax might be a carcharodontosauridae (or carcharodontosaurid). After a personal evaluation of its mid-dorsal neural arch and atlas, it seems to me that Saurophaganax is indeed a carcharodontosaurid.

 -Since Saurophaganax is an early carcharodontosaurid, the size I was able to obtain for it seems accurate. 

 -Mickey Mortimer in 2018 did a Lori analysis, and put Saurophaganax as a relative of Acrocanthosaurus and Concavenator, other carcharodontosaurids.

Allosaurus:
Update (2/22/20): According to Evers et al., (2020), there doesn't seem to be any diagnostic features between the multiple species of Allosaurus, based on a study of multiple skulls (mainly cheek or jugal bones) ("Introduction," Figure 5, "Discussion," and "Conclusion"). Therefore, it seems that Allosaurus fragilis is the only valid species of Allosaurus so far. Therefore, all species and specimens listed below belong to Allosaurus fragilis.

Femurs:
1. NMMNH P-26083:
Femur: 103.0 cm. (Measured on 9/8/19 in Heckert et al., 2003, pg. 319, "B")

 Originally called an unidentified allosauridae in Heckert et al., (2003), the paper says that the bones are too large to belong to Allosaurus. However, the specimen doesn't share any similar features to Saurophaganax (pg. 320-321). Mickey Mortimer from the Theropod Database also identified this specimen as Allosaurus fragilis. Interestingly, Lucas and Heckert (2015) said that the specimen was "Saurophaganax-like," but still calls it an allosaurid instead of directly calling it Saurophaganax (pg. 100). Since Saurophaganax is a carcharodontosaurid now, it seems more likely than ever that this specimen is Allosaurus.

Suchomimus:
Femur: 107.5 cm.
Body: 10.0 meters.

107.5 - 103 = 4.5.

8. SMA 0005 ("Big Al TWO/2"):
Size estimate: 7.6 meters. (Foth et al., 2015, "Materials and Methods") (BHIGR)

Stated to have been 12% larger than MOR 693 ("Big Al"). (Foth et al., 2015, "Materials and Methods") However, "Big Al" was stated to have been 8.0 meters long (Breithaupt, Retrieved in 2019, stated near "Figure 5"). I got 10.6 meters. Foth et al., (2015) said that SMA was a large, and possibly an adult, specimen ("Abstract"), so SMA would have to be a large specimen.

Coracoid Length (Up to beginning of gleniod facet [marked]): 17.2 cm. (Measured in Foth et al., 2015, Figure 8, "A")

USNM 4734:
Coracoid (Gilmore, 1920, pg. 58):
Length: 12 cm.
Width: 17 cm.
Scapula-Coracoid (Gilmore, 1920, pg. 58): 
Length: 79.5 cm.
Body: 7.9 meters.

17.2 - 12 = 5.2.
5.2/12*100 = 43.3% increase.
7.9 m + 43.3% = 37 feet (11.3 meters).

I thought that 11.3 meters might have been a little too big, but if SMA was a "large, almost complete, possibly adult" specimen, then 11.3 meters does fall within the adult size range for an average. As I've said before, I got 10.6 meters for "Big Al," so I'll keep this length.

 Update (2/12/20): "Big Al 2" is now considered to be A. jimmadseni (Chure and Loewen, 2020).

Update (5/8/21):
Skull: 79 cm (BHIGR).

9. AMNH 5767:
Originally called "Epanterias amplexus" (Cope, 1878, pg. 406), and considered a sauropod. However, it was revealed to have been a theropod (Osborn and Mook, 1912, pg. 282). It's now considered either to be indistinguishable from Allosaurus fragillis (Osborn and Mook, 1912, pg. 282), or a nomen dubium by Paul and Carpenter (2010) (pg. 54). However, aside from the holotype, Paleontologists Robert Bakker is said to have discovered a second specimen (called CPS 99 by Theropod Database) (Browne, 1990). Therefore, Epanterias might be its own species after all. I can't find any measurements for CPS 99, so I'll just stick with the holotype.

Size:
Size estimate: 50 feet. (Dr. Bakker in Browne, 1990) (Lee Dye, 1990) (Popular Science, 1990, pg. 26) (Real Colorado Travel, 2012) (North Forty News, 2017)

Coracoid (On Bottom) (Paleofile): 
Length: 24 cm. (I got it twice on 9/3/19)
Width: 34.0 cm. 
Scapula-coracoid (Paleofile):
Length: 132 cm.
Allosaurus fragilis Specimen USNM 4734:
Coracoid (Gilmore, 1920, pg. 58):
Length: 12 cm.
Width: 17 cm.
Scapula-Coracoid (Gilmore, 1920, pg. 58): 
Length: 79.5 cm.
Body: 7.9 meters.

Coracoid Length:
24 - 12 = 12.
12/12*100 = 100% increase.
7.9 m + 100% = 52 feet (15.8 meters).

Scapula-coracoid Length:
79.5 - 132 = 52.5.
52.5/79.5*100 = 66% increase.
7.9 m + 66% = 43 feet (13.1 meters).

 Allosaurus fragilis Specimen SMA 0005 ("Big Al 2"):
Coracoid Length (Up to gleniod facet): 17.2 cm.
Body: 11.3 meters.

 24 - 17.2 = 6.8.
6.8/17.2*100 = 39.5% increase.
11.3 m + 39.5% = 52 feet (15.8 meters).

I'm a bit torn on this. The coracoid is huge. I thought part of the scapula was broken off with the coracoid. However, Osborn and Mook (1912) (pg. 284) said that only the coracoid was broken off from the scapula. I was skeptical when I got the 15.8-meter length from USNM, but I got the same length using "Big Al TWO." Therefore, based on the length of the coracoid, Epanterias was a whooping 15.8 meters! It also seems consistent with the 50-foot estimate by Bakker. Paleontologist Mickey Mortimer in 2003 said that Epanterias was larger than Saurophaganax. Plus, the coracoid is the only part of the scapulacoracoid that exists, so I'll go with that length.

Is It Allosaurus?
As for being its own species, I don't know whether to call this animal Epanterias or Allosaurus. As stated before, Paul and Carpenter (2010) said that it was a nomen dubium at best (pg. 54). Osborn and Mook (1912) said that Epanterias cannot be distinguished from Allosaurus (fragilis) (pg. 282). With that quote in mind, I'm going to assign "Epanterias" to Allosaurus fragilis.

 Notes: 
-North Forty News (2017) said that the bones discovered in 1990, originally designated to Epanterias, are now assigned to Allosaurus.

  -In a dml.cmnh.org email from 2000, it was also stated that the 1990's Epanterias fossil was a large specimen of Allosaurus fragilis.

 -Paleontologist Andrea Cau (2009) also says that Epanterias is Allosaurus fragilis.

 -Weishampel et al., (2004) says that Epanterias is Allosaurus fragilis (Pg. 74-75).

 -Madsen (1976/1993) also said that Epanterias was Allosaurus fragilis (pg. 5). 

 Personal Observation: The 1st or 2nd dorsal vertebrae of AMNH 5767 (Osborn and Mook, 1912, pg. 283) is identical to a normal 2nd Allosaurus fragilis dorsal vertebrae seen in Madsen (1976/1993) (pg. 85, "A"-"C"). Therefore, AMNH 5767 is Allosaurus fragilis.

Update (3/15/21): Acrocanthosaurus NCSM 14345:
Scapulacoracoid: 118 cm (Currie and Carpenter, 1999, Table 1).
Body: 12.0 meters.

118 - 132 = 14.
14/118*100 = 11.9% increase.
12 m + 11.9% = 44 feet (13.4 meters).

25.1/85*100 = 29.5% decrease.
7.9 m - 29.5% = 18 feet (5.6 meters).

 This seems to have been a juvenile. It was also concluded that the holotype was not fully grown in Chure and Loewen (2020) ("Ontogenetic Assessment of Dino 11541," p. 4-5).

Spinosaurus:
1. FSAC-KK 11888 (Spinosaurus Neotype):
(Taken from Ibrahim et al., 2014, "Supplementary Materials"):
Skull: 112.0 cm. (Pg. 30)
Femur: 61 cm. (Pg. 30 and 33)
Age: 17. (Pg. 14)

Suchomimus:
Skull: 119.0 cm. (Hendrickx et al., 2016)
Femur: 107.5 cm. (Sereno et al., 1998)
Length: 10 meters.

Femur:
61 - 107.5 = 46.5.
46.5/107.5*100 = 56.7% increase.
10 m - 56.7% = 14 feet (4.3 meters) for neotype at age 17.
Age 18: 15 feet (4.6 meters).

Skull:
119.0 -112.0 = 7.
7/119*100 = 5.9% decrease.
10 m - 5.9% = 31 feet (9.4 meters) at age 17.
Age 18: 32 feet (9.8 meters).

The body length I obtained from the skull seems a lot more appropriate. Spinosaurus had a short femur compared to other spinosaurs.

FSAC-KK 11888's Total Length: 31 feet (9.4 meters). 
Age: 17.
Age 18: 32 feet (9.8 meters)(?). (My estimate)

Update (6/29/29): Skull Length: 123 cm (Ibrahim et al., 2020, Supplementary Materials, Body dimensions, body mass, body segment masses, and whole body center of mass pg. 1)

Suchomimus:
Skull: 119.0 cm. (Hendrickx et al., 2016)
Length: 10 meters.

119 - 123 = 4.
4/119*100 = 3.4% increase.
10.0 m + 3.4% = 34 feet (10.3 meters).

2. IPHG 1912 VIII 19 (Holotype):
Discovered by Ernst Stromer in 1915. According to his drawing, the animal was 30 feet long (9 meters):
Lakin and Longrich (2018) gave the same length (par. 3).

Mandible: 120 cm (Estimated). (Stromer, 1915, pg. 5)
Dentary: 60 cm (I think). (Stromer, 1915, pg. 5)

IPHG 1912 VIII 19's Dentary (Candiero et al., 2018, Figure 3, "A"):
-Length: 56 cm (Measured on 3/16/21, A).
-(?)Complete Length: 65 cm (Complete) (My estimate). (Measured on 3/29/20 in Candiero et al., 2018, Figure 3, "A").
-Dentary Tooth Row: 37 cm (Measured on 3/20/21, B).

Suchomimus:
Skull: 119.0 cm.
Dentary: 67.7 cm (at best). 
Length: 10 meters.

Mandible:
120.0 - 119.0 = 1.
1/119*100 = 0.8% increase.
10 m + 0.8% = 33 feet (10.1 meters)

Dentary:
67.7 - 65 = 2.7.
2.7/67.7*100 = 4% decrease.
10 m - 4% = 9.6 meters.

I think I'll go with the dentary length.

Update (10/26/20): Dorsal Vertebra "H" (6) Centrum Length: 19 (calculated) (Stromer, 1915, pg. 24 "Measurements of Vertebrae in cm").

FSAC-KK 11888 (Neotype):
Dorsal Vertebra 6 Centrum Length: 17 cm (Ibrahim et al., 2014, Supplementary Materials, pg. 32).
Length: 10.3 meters.

19 - 17 = 2.
2/17*100 = 11.8% increase.
10.3 m + 11.8% = 38 feet (11.5 meters).

Update (12/17/20): Thoracic vertebra "h" is before "f" (Stromer, 1934, pg. 9). "G" from Stromer (1915) (p. 24) would be dorsal/thoracic vertebra 6.

Vertebra "g" Centrum Length: 17 cm (Stromer, 1915, pg. 25 "Measurements of Vertebrae in cm").

FSAC-KK 11888 (Neotype):
Dorsal Vertebra 6 Centrum Length: 17 cm (Ibrahim et al., 2014, Supplementary Materials, pg. 32).
Length: 10.3 meters.

Holotype's Length (Based on Neotype): 34 feet (10.3 meters).

24 - 22 = 2.
2/24*100 = 8.3% decrease.
112 cm + 8.3% = 102.7 cm.

I'm going with the 102.7-cm length. This is also an adult specimen.

FSAC-KK 11888:

 Pycnonemosaurus:
Pycnonemosaurus is said to be the largest abelisaurid (Grillo and Delcourt, 2017), based on its tibia. However, the tibia of Carnotaurus, while skinnier than Pycnonemosaurus, appears to have a longer than Pycnonemosaurus. Bonaparte et al., (1990) gave an estimated tibia length of about 97 cm (pg. 31). Pycnonemosaurus' tibia is said to have been 84.5 (Kellner and Campos, 2002) to 87.0 cm (Grillo and Delcourt, 2017) (FAPESP, 2017). (The tibia is already 83 cm, as seen in Grillo and Delcourt, 2017, pg. 72, but Kellner and Campos said that the bone is incomplete on pg. 166) Therefore, Carnotaurus is taller and longer than Pycnonemosaurus.

However, while Carnotaurus seems to be longer, Pycnonemosaurus seems to be heavier. Grillo and Delcourt (2017) gave Pycnonemosaurus a length of 8.7 meters. However, I'm going to measure its tibia against Carnotaurus'.

Pycnonemosaurus' Tibia:
1. 84.5 cm. (Kellner and Campos, 2002, pg. 166)
2. 87 cm. (Grillo and Delcourt, 2017, pg. 72) (FAPESP, 2017)
Note: Looks actually like 83 cm based on a chart on pg. 72.

Update (9/8/19): Tibia is 83 cm. (Measured in Grillo and Delcourt, 2017, pg. 72 and *Kellner and Campos, 2002, pg. 167)

Carnotaurus: 
Tibia: 97 cm (Estimated). (Bonaparte et al., 1990)
Length: 9.6 meters.

97 - 83 = 14.
14/97*100 = 14.4% decrease.
9.6 m - 14.4% = 27 feet (8.2 meters).

Not too far off from the original 8.7-meter estimate, surprisingly. I will say that the tibia is wide compared to Carnotaurus (Grillo and Delcourt, 2017, pg. 72), so Pycnonemosaurus must have been heavier.

Pycnonemosaurus' Total Length: 27 feet (8.2 meters).

Angaturama's Total Length: 24 feet (7.3 meters).

Since Sales and Schultz (2017) says that the specimens of each genera do seem to overlap due to: coming from the same stratigraphic unit (pg. 2-3), having a dorsal sagittal crest (pg. 18), and a tooth Lm3 (pg. 19). If these two genera are the same, then Angaturama would be Irritator (pg. 19). The authors conclude that the two specimens might have belonged to two different individuals, and that more overlapping material is needed (pg. 21). I will keep that in mind, but I think there is enough evidence to place Angaturama as Irritator for now, at least until more papers are published.

Dal Sasso et al., (2005) also combined the two genera into the same genus (pg. 894, Figure 3).
