Morphometry, Bite-Force, and Paleobiology of the Late Miocene Caiman Purussaurus brasiliensis

Abstract: Purussaurus brasiliensis thrived in the northwestern portion of South America during the Late Miocene. Although substantial material has been recovered since its early discovery, this fossil crocodilian can still be considered as very poorly understood. In the present work, we used regression equations based on modern crocodilians to present novel details about the morphometry, bite-force and paleobiology of this species. According to our results, an adult Purussaurus brasiliensis was estimated to reach around… Show more

“…More complete cranial and mandibular material from this formation was later described and figured Aureliano et al, 2015). Besides P. brasiliensis, two more species were described, P. neivensis from the middle Miocene, La Venta fauna, Colombia (Mook, 1941;Langston, 1965) It is difficult in many cases, however, to identify isolated specimens down to the species level.…”

“…Some of them, such as Purussaurus Barbosa‐Rodrigues , reached giant sizes with about 12.5 metres long, with a daily food intake of about 40.6 kg (Aureliano et al . ). The abundance and diversity of such Miocene crocodilian fauna could indicate that they were the potential main predators of neoepiblemids and other rodents.…”
