Notosuchia

Live reconstruction of Notosuchus, the eponymous genus of Notosuchuia

The Notosuchia are a group from the Crocodylomorpha who lived during the Cretaceous period. Fossils were found in South America, Africa, and Asia. The Notosuchia lived terrestrial ( country dweller ). There are different diet types in the Notosuchia known: Thus lived Chimaerasuchus herbivorous (plant- eating ), Simosuchus omnivorous ( omnivorous ) and Baurusuchus carnivorous ( meat- eating ).

Features

Notosuchia were small to medium-sized, short-snouted crocodiles. The group includes many species with very specialized features with a, including mammal -like teeth, flexible, protective shield - like body armor, similar to those of today's armadillos ( Armadillosuchus ), and possibly fleshy cheeks and pigs reminiscent snouts ( Notosuchus ).

This subordination was first described in 1971 by Zulma Gasparini scientifically, but since then underwent several phylogenetic revisions. According to Gasparini can define this group by a number of characteristics of other groups: for example, the skull and muzzle were relatively short. The Antorbitalfenster was open and not closed, as in some other crocodile groups. The eye sockets ( orbits ) were located laterally on the skull. The tooth row was short.
