Protosuchidae
Protosuchidae was a family of crocodylomorph reptiles from the Late Triassic, Jurassic, and Cretaceous time periods. They were closely related to the Gobiosuchidae. Distribution Triassic protosuchids are known from Lesotho, Argentina, and Arizona. Jurassic protosuchids are known from Nova Scotia, Poland, South Africa, and Arizona. Cretaceous protosuchids are known from China. Ecology Protosuchids were carnivores. An unnamed species of protosuchids known only from teeth was an herbivore A herbivore is an animal anatomically and physiologically adapted to eating plant material, for example foliage or marine algae, for the main component of its diet. As a result of their plant diet, herbivorous animals typically have mouthp ....

Orthosuchus
''Orthosuchus'' (meaning "straight crocodile") is an extinct genus of protosuchian crocodyliform that lived during the Early Jurassic, about 196 million years ago. It was first discovered in 1963 in the Red Beds Formation in the Qacha's Nek Province of Lesotho, southern Africa. The characteristics showed on its postcranial skeleton and the skull indicated that it is a Crocodyliform.Nash, Diane. "A Crocodile from the Upper Triassic of Lesotho." ''Journal of Zoology''. Blackwell Publishing Ltd, 20 Aug. 2009. Web. 05 Mar. 2017. The finding is significant since some of the characteristics found on this specimen were believed to be absent until Jurassic. Description ''Orthosuchus'' has a body proportion similar to lizards, with a body length about 0.6 meters, and a flattened skull, a typical skull of crocodilian.Diane, Nash S.

Erythrochampsa
''Erythrochampsa'' ("red crocodile") is an extinct genus of protosuchian crocodylomorph. Fossils have been found from the Red Beds of the Stormberg Group, the youngest group of strata from the Karoo Supergroup outcropping in South Africa. Description Material from ''E. longipes'', the type (and only) species of ''Erythrochampsa'', was originally referred to the genus ''Notochampsa'' in 1904 along with specimens of another species named ''N. istedana''. However, certain features of material from this species, such as divided external nares, have been considered to be indications of a position within Pseudosuchia rather than Crocodilia as was originally supposed. Despite this, the material of ''N. longipes'' remained highly suggestive of a crocodilian, and thus the species was eventually placed within its own distinct genus, ''Erythrochampsa'', in 1924. It was placed in the family Notochampsidae, and was considered closely related to ''Notochampsa'', whose position within Croc ...

Jurassic Reptiles
The Jurassic ( ) is a geologic period and stratigraphic system that spanned from the end of the Triassic Period million years ago (Mya) to the beginning of the Cretaceous Period, approximately Mya. The Jurassic constitutes the middle period of the Mesozoic Era and is named after the Jura Mountains, where limestone strata from the period were first identified. The start of the Jurassic was marked by the major Triassic–Jurassic extinction event, associated with the eruption of the Central Atlantic Magmatic Province. The beginning of the Toarcian Stage started around 183 million years ago and is marked by an extinction event associated with widespread oceanic anoxia, ocean acidification, and elevated temperatures likely caused by the eruption of the Karoo-Ferrar large igneous provinces. The end of the Jurassic, however, has no clear boundary with the Cretaceous and is the only boundary between geological periods to remain formally undefined. By the beginning of the Jurassic, t ...

Protosuchia
Protosuchia is a group of extinct Mesozoic crocodyliforms. They were small in size (~1 meter in length) and terrestrial. In phylogenetic terms, Protosuchia is considered an informal group because it is a grade of basal crocodyliforms, not a true clade. Classification Recent phylogenetic analyses have not supported Protosuchia as a natural group. However, two studies found a clade of Late Triassic-Early Jurassic animals:Pol D, Ji S-a, Clark JM, Chiappe LM. 2004. Basal crocodyliforms from the Lower Cretaceous Tugulu Group (Xinjiang, China), and the phylogenetic position of ''Edentosuchus''. ''Cretaceous Research'' 25: 603-622.Fiorelli LE, Calvo JO. 2007.

Carnivore
A carnivore , or meat-eater (Latin, ''caro'', genitive ''carnis'', meaning meat or "flesh" and ''vorare'' meaning "to devour"), is an animal or plant whose food and energy requirements derive from animal tissues (mainly muscle, fat and other soft tissues) whether through hunting or scavenging. Nomenclature Mammal order The technical term for mammals in the order Carnivora is ''carnivoran'', and they are so-named because most member species in the group have a carnivorous diet, but the similarity of the name of the order and the name of the diet causes confusion. Many but not all carnivorans are meat eaters; a few, such as the large and small cats (felidae) are ''obligate'' carnivores (see below). Other classes of carnivore are highly variable. The Ursids, for example: While the Arctic polar bear eats meat almost exclusively (more than 90% of its diet is meat), almost all other bear species are omnivorous, and one species, the giant panda, is nearly exclusively herbiv ...

Late Triassic
The Late Triassic is the third and final epoch (geology), epoch of the Triassic geologic time scale, Period in the geologic time scale, spanning the time between annum, Ma and Ma (million years ago). It is preceded by the Middle Triassic Epoch and followed by the Early Jurassic Epoch. The corresponding series (stratigraphy), series of rock beds is known as the Upper Triassic. The Late Triassic is divided into the Carnian, Norian and Rhaetian Geologic time scale, Ages. Many of the first dinosaurs evolved during the Late Triassic, including ''Plateosaurus'', ''Coelophysis'', and ''Eoraptor''. The Triassic–Jurassic extinction event began during this epoch and is one of the five major mass extinction events of the Earth. Etymology The Triassic was named in 1834 by Friedrich August von Namoh, Friedrich von Alberti, after a succession of three distinct rock layers (Greek meaning 'triad') that are widespread in southern Germany: the lower Buntsandstein (colourful sandstone'')'', t ...
