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),[1] is all that is known from the genus.[2] It may be a junior synonym of Eocaiman.[3] 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.[4] The type species, N. stromeri, was named in 1937.[5]
