Size Calculations for Crocodyliformes:

 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."

1. Cerrejonisuchus:

Skulls (Largest): 31.4 cm (Table 1).

26 - 31.4 = 5.4.

5.4/26*100 = 20.8% increase.

1.829 m + 20.8% = 7 feet (2.2 meters).

Cerrejonisuchus' Total Length: 7 feet (2.2 meters).

2. Eothoracosaurus:

MSU 3293:
Skull: 89.7 cm (For now).

Cerrejonisuchus:

Skulls (Largest): 31.4 cm.

Body: 2.2 meters.

89.7 - 31.4 = 58.3.

58.3/31.4*100 = 185.7% increase.

2.2 m + 185.7% = 21 feet (6.3 meters).

Eothoracosaurus' Total Length: 21 feet (6.3 meters).

Carcharodontosaurus and Elosuchus by David Bonadonna:

Largest Skull: 107.7 cm (Meunier and Larsson, 2017, Table 1).

Eothoracosaurus:

Skull: 89.7 cm.

Body: 6.3 m.

107.7 - 89.7 = 18.

18/89.7*100 = 20.1% increase.

6.3 m + 20.1% = 25 feet (7.6 meters).

Elosuchus' Total Length: 25 feet (7.6 meters).
