Notosuchus (

crocodyliforms. It was terrestrial, living approximately 85 million years ago in the Santonian stage of the Late Cretaceous.[1]

Description

Notosuchus was relatively small, reaching 1.5 m (4.9 ft) in length and a weight of 36 kg (79 lb).[2] Remains have been found in the Bajo de la Carpa Formation in Patagonia, Argentina. First named in 1896, Notosuchus was the first known notosuchian.[3] The type species is N. terrestris. A second species, N. lepidus, was named in 1957.[4]

A paper published in 2008 by Fiorelli and Calvo described new remains of the

mastication by preventing food loss.[5] A re-description of the skull material has since lent evidence toward minimal soft-tissue enhancement to the snout of Notosuchus.[7]
