Eocaiman is an extinct genus of caiman containing species living from the Early Paleocene to Miocene in what is now Argentina (Salamanca and Sarmiento Formations), Itaboraí Formation of Brazil and Colombia (Honda Group).[1][2] Eocaiman contains three described species: E. cavernensis, E. palaeocenicus, and E. itaboraiensis, and is typically recovered as one of the more basal members of Caimaninae.[3][4] Notocaiman was synonymized with Eocaiman paleocenicus in 2022.[5]
