Mystriosuchin
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.

Machaeroprosopus Mccauleyi
''Machaeroprosopus'' is an extinct genus of mystriosuchin leptosuchomorph phytosaur from the Late Triassic of the southwestern United States. ''M. validus'', once thought to be the type species of ''Machaeroprosopus'', was named in 1916 on the basis of three complete skulls from Chinle Formation, Arizona. The skulls have been lost since the 1950s, and a line drawing in the original 1916 description is the only visual record of the specimen. Another species, ''M. andersoni'', was named in 1922 from New Mexico, and the species ''M. adamanensis'', ''M. gregorii'', ''M. lithodendrorum'', ''M. tenuis'', and ''M. zunii'' were named in 1930. Most species have been reassigned to the genera ''Smilosuchus'', ''Rutiodon'', or ''Phytosaurus''. Until recently, ''M. validus'' was considered to be the only species that has not been reassigned. Thus, ''Machaeroprosopus'' was considered to be a ''nomen dubium'' or "doubtful name" because of the lack of diagnostic specimens that can support its dis ...

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.

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. External links ''Angistorhinopsis''at Palaeos Palaeos.com is a web site on biology, paleontology, phylogeny and geology and which covers the history of Earth.

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] |
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. ''Pravusuc ...

Leptosuchus Crosbiensis
''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 the o ...
