Description

Gryposuchus is an extinct genus of gavialoid crocodilian. It is the type genus of the subfamily Gryposuchinae. Fossils have been found from Argentina, Colombia, Venezuela, Brazil and the Peruvian Amazon. The genus existed from the Middle Miocene to Late Pleistocene (Friasian to Lujanian). One recently described species, G. croizati, grew to an estimated length of 10 metres (33 ft).
