Notocaiman

Notocaiman is an extinct genus of alligatorid crocodylian. A fragmentary and poorly preserved left dentary found in the Peñas Coloradas Formation of Argentina that presumably dates back to the Paleocene epoch (Peligran-Riochican), is all that is known from the genus. It may be a junior synonym of Eocaiman. Similarities between the remains of Notocaiman and comparable material from the alligatoroid Listrognathosuchus have been observed, but have not been taken as evidence for synonymy. The type species, N. stromeri, was named in 1937.
