Patagosuchus is an extinctgenus of peirosauridcrocodyliform known from the early Late CretaceousPortezuelo Formation of Neuquén Province, western central Argentina. It contains a single species, Patagosuchus anielensis. It is distinguished from other peirosaurids by its extremely heterodont dentition, which includes small serrated teeth at the front of the jaws with much larger, laterally compressed caniniform teeth behind them. Patagosuchus also has large spaces between its teeth called interalveolar spaces that are not found in any other peirosaurid.[1]
Patagosuchus was first described and named by Gabrel Lio, Federico L. Agnolína, Rubén Juarez Valieri, Leonardo Filippi and Diego Rosales in 2015 and the type species is Patagosuchus anielensis. The generic name refers to Patagonia, and suchus, Latinized from the Greeksouchos, an Egyptian crocodile god. The specific name refers to the city of Añelo, near which the holotype was discovered and collected.
