Mystriosuchini
Mystriosuchini, historically known as Pseudopalatinae, is an extinct tribe (formerly subfamily) of derived phytosaurs in the clade Leptosuchomorpha. As with all other phytosaurs, mystriosuchins lived during Late Triassic. The name is derived from the genus '' Mystriosuchus''. Genera classified in Mystriosuchini include '' Coburgosuchus'', '' Machaeroprosopus'', '' Mystriosuchus'', '' Nicrosaurus'' and ''Redondasaurus''.Hungerbühler A. 2002.

Pravusuchus Hortus
''Pravusuchus'' is an extinct genus of leptosuchomorph parasuchid phytosaur known from the Late Triassic ( Norian stage) of Arizona, United States. It contains a single species, ''Pravusuchus hortus'', which is known from three specimens. These specimens were previously referred to ''Smilosuchus'' or to ''Leptosuchus'', but ''Pravusuchuss autapomorphy, its phylogenetic position as well as a trait shared with mystriosuchins, justified the erection of a new taxon for the material. Discovery and naming ''Pravusuchus'' was first described and named by Michelle R. Stocker in 2010 and the type species is ''Pravusuchus hortus''. The generic name is derived from Latin, ''pravus'', "evil" or "wicked", and Greek, ''souchus'', for the Egyptian crocodile-headed god Sobek. The specific name, ''hortus'', is the Latin word for park or grounds. The name refers to Devil's Playground, the locality in Petrified Forest National Park from which all specimens of this taxon were collected. ''Pravu ...

Paleorhinus
''Paleorhinus'' (Greek: ''"Old Nose"'') is an extinct genus of widespread basal (phylogenetics), basal phytosaur known from the Late Triassic (late Carnian stage). The genus was named in 1904 based on the type species ''Paleorhinus bransoni'', which is known from Wyoming and Texas in the United States. Another valid species, ''Paleorhinus angustifrons'' from Bavaria, Germany, is also commonly referred to the genus. ''Paleorhinus'' had a length of about . ''Paleorhinus'' has had a complicated Taxonomy, taxonomic history involving frequent synonymy between diagnostic and undiagnostic material. This is mainly due to the fact that it is a quintessential basal phytosaur, mostly distinguished by a lack of specializations rather than unique traits. Historically, it was common practice to Lumpers and splitters, lump all basal phytosaurs into only one or two genera, rendering those genera Paraphyly, paraphyletic Evolutionary grade, evolutionary grades ancestral to later phytosaurs.

Angistorhinopsis
''Angistorhinopsis'' is an extinct genus of altirostral (long-snouted) mystriosuchin phytosaur. It was named for its supposed resemblance to '' Angistorhinus'' by Friedrich von Huene in 1922. Fossils have been found in Switzerland and date back to the latest Norian and Rhaetian stages of the Late Triassic, making it the youngest known phytosaur to have existed in Europe and, along with ''Redondasaurus'' from the United States, one of the last surviving members of Phytosauria before the group became extinct during the Triassic–Jurassic extinction event 199.6 million years ago.

Coburgosuchus
''Coburgosuchus'' is an extinct genus of mystriosuchin phytosaur. The genus was named for Coburg, Germany, the type locality where specimens have been found dating back to the Late Triassic. It has at times been considered a nomen dubium due to the fragmentary nature of the material associated with the genus, and it may prove to be synonymous with other phytosaurs such as '' Nicrosaurus'' or ''Phytosaurus ''Phytosaurus'' (meaning "plant lizard") is a dubious genus of extinct parasuchid phytosaur found in an outcrop of the Keuper (likely the Exter Formation) in Germany.

Nicrosaurus
''Nicrosaurus'' (/nɛkroʊˈsɔrəs/) is an extinct genus of phytosaur reptile existing during the Late Triassic period. Although it looked like a crocodile (and probably lived like the more terrestrial crocodylomorphs), it was not closely related to these creatures, instead being an example of parallel evolution. The main difference between ''Nicrosaurus'' (and all other phytosaurs) and modern crocodiles is the position of the nostrils – ''Nicrosauruss nostrils, or external nares, were placed directly in front of the forehead, whereas in crocodiles, the nostrils are positioned on the end of the snout. A 2013 study has also found that ilium of ''Nicrosaurus'' is quite distinctive from all other phytosaurs. The genus was named by German paleontologist, Dr. Eberhard Fraas, in 1866, possibly after the Neckar river of southwestern Germany, near which it was found. Description and paleobiology Some distinguishing anatomical features of ''Nicrosaurus'' are the external nares at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ...

Leptosuchus Studeri
''Leptosuchus'' is an extinct genus of leptosuchomorph phytosaur with a complex taxonomical history. Fossils have been found from the Dockum Group and lower Chinle Formation outcropping in Texas, New Mexico, and Arizona, USA, and date back to the Carnian stage of the Late Triassic. Currently there are believed to be four species of ''Leptosuchus''. All species share in common a similar position of the temporal arch below the skull roof and a posterior process of the squamosal that extends farther than the paroccipital process.Long, R. A., and Murry, P. A. (1995). "Late Triassic (Carnian and Norian) tetrapods from the southwestern United States". ''New Mexico Museum of Natural History and Science Bulletin'' 4:1-254. The type species is ''L. crosbiensis'', which was named in 1922 on the basis of material found from Texas. ''L. adamanensis'' was first described in 1930 as a species of ''Machaeroprosopus'' from the Blue Mesa Member of Petrified Forest National Park, along with t ...

Smilosuchus Lithodendrorum
''Smilosuchus'' (meaning "chisel crocodile") is an extinct genus of leptosuchomorph parasuchid from the Late Triassic of North America. History The type species was first described in 1995 as a replacement generic name for ''Leptosuchus gregorii''. Because of the large rostral crest it possessed, it was considered to be distinct enough from other species of ''Leptosuchus'' (all of which had smaller and more restricted crests) to be within its own genus. Some studies seem to suggest that ''Smilosuchus'' is congeneric with ''Leptosuchus'', as the enlarged crest could have been independently developed in ''Leptosuchus''. However, newer studies support the idea that ''Smilosuchus'' is distinct from the type species of ''Leptosuchus'', ''Leptosuchus crosbiensis''. Phylogenetic analyses suggest that ''Smilosuchus'' is more closely related to mystriosuchins than to ''Leptosuchus'' species.
