Let's talk about Patagotitan!

Description:
Patagotitan is a member of the titanosauria (Otero et al., 2020, "Systematic Paleontology"), and it was one of the largest animals to have ever walked the Earth. It lived during the Albian of the Cerro Barcino Formation, 113-101 million years ago, in South America (Carballido et al., 2017, "Systematic palaeontology": "Type locality and horizon," Figure 3) (Otero et al., 2020, "Systematic Paleontology: Locality and Horizon"). It was 110-157 feet long (33.4-47.9 meters). As for its weight, it was originally given 69 tons (Carballido et al., 2017, "Body Mass" p. 2), but Paul (2019) gave it 52 tons (pg. 339 Table 1). Otero et al., (2020) gave it 57 tons ("Abstract," "Recalculating the Body Mass of Patagotitan," "Conclusions"). Larramendi et al., (2020) gave it 56,419 kg (62 tons) to the holotype (MPEF-PV 3400) (Table 10).

Patagotitan's Time Period (Carballido et al., 2017, Figure 3):

On October 10, 2019, it was announced that sauropod dinosaurs would have had rhamphotheca, or a beak-like structure made of keratin. This beak would have protected the sauropod's teeth and kept them in place, since fossilized sauropod teeth are usually found in good condition and connected to their skulls (John Pickrell, 10/10/19) (Pickrell, 10/17/19). Interestingly, dinosaurs couldn't move their tongues (Mindy Weisberger, 2018) (ScienceDaily, 2018).

Friends:
Patagotitan lived alongside the rebbachisaurs Limaysaurus (59-68 feet; 17.9-20.8 meters) and Cathartesaura (56 feet; 17.1 meters), the titanosaurs Andesaurus (52 feet; 15.7 meters), MMCH-Pv 47 (71 feet; 21.7 meters) and Argentinosaurus (83 feet; 25.3 meters). It also coexisted with the
ornithopod Anabisetia.

Predators:
Patagotitan's enemies consisted of Giganotosaurus (36-50 feet; 10.9-15.3 meters), the abelisaurs Ekrixinatosaurus (24 feet; 7.2 meters) and Skorpiovenator (15 feet; 4.5 meters), the dromeosaurs Buitreraptor (4 feet; 1.3 meters) and Unenlagia (8-9 feet; 2.3-2.8 meters), the neovenatorid Gualicho (24 feet; 7.2 meters), and perhaps Spinosaurus (27-55 feet; 8.1-16.8 meters). However, Spinosaurus would have preferred rivers and fish (Kristen Rogers, 2020, "Competing for food," p. 1).
