Baurusuchus is an extinct genus of baurusuchid mesoeucrocodylian, which lived in Brazil from 90 to 83.5 million years ago, in the Late Cretaceous period. It was a terrestrial predator and scavenger, estimated to reach up to 113.4 kilograms (250 lb) in weight.[1]Baurusuchus lived during the Turonian to Santonian stages of the Late Cretaceous Period, in Adamantina Formation, Brazil.[2] It gets its name from the Brazilian Bauru Group ("Bauru crocodile"). It was related to the earlier-named Cynodontosuchus rothi, which was smaller, with weaker dentition.[3] The three species are B. pachechoi, named after Eng Joviano Pacheco, its discoverer,[4]B. salgadoensis (named after General Salgado County in São Paulo, Brazil)[5] and B. albertoi (named after Alberto Barbosa de Carvalho, Brazilian paleontologist).[2] The latter species is disputed (see phylogeny section). Its relatives include the similarly sized Stratiotosuchus from the Adamantina Formation, and Pabweshi, from the Pakistani Pab Formation.
