Physical CharacteristicsEdit

Notosuchus was small, reaching 1.5 m (5 ft) in length and a weight of 36 kg. Remains have been found in the Bajo de la Carpa Formation in Patagonia, Argentina. First named in 1896, Notosuchus was the first known notosuchian. The type species is N. terrestris. A second species, N. lepidus, was named in 1957.

Trunk? Edit

A paper published in 2008 by Fiorelli and Calvo described new remains of the type species N. terrestris. In it, the authors suggested that the skull would have supported a short snout, or "hog's snout" as well as fleshy upper and lower mouth protuberances. The anteriorly directed nares and the absence of a bony nasal septum (which presumably indicates cartilaginous tissue serving its place) provide evidence for a proboscis snout, while striations on the surface of the nasal bones and the lower jaw most likely acted as attachment points for the nasoprotuberancial muscles and the depressor muscle, respectively. Additionally, the authors suggested that a lateral rim on the dentary as well as numerous aligned neurovascular foramina are evidence of soft cheek-like muscular tissue. The function of the proboscis was likely used for catching food by sniffing the environment.
