Pseudopalatinae
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.

Protome Batalaria
''Protome'' is an extinct genus of parasuchid phytosaur from the Late Triassic of Arizona, represented by a single species, ''Protome batalaria''. It is known from a single holotype incomplete, partially disarticulated skull and left lower jaw called PEFO 34034 from the Upper Lot's Wife beds, Sonsela Member of the Chinle Formation in Petrified Forest National Park. The skull was discovered in 2004 by Michelle Stocker and Bill Parker and was described by them as a specimen of '' Smilosuchus adamanensis'' (then a species of ''Leptosuchus''). It was placed in the new genus ''Protome'' in 2012. The genus name ''Protome'' is the Greek word for an animal's face. The specific name ''batalaria'' is the Latin word for battleship, which is a reference to Battleship NW, the locality within Petrified Forest where the skull was found. Description ''Protome'' has a long, narrow, tubular-shaped snout. It has a partial rostral crest at the back of the snout, a feature which it shares with phyto ...

Phytosaurs
Phytosaurs (Φυτόσαυροι in greek) are an extinct group of large, mostly semiaquatic Late Triassic archosauriform reptiles. Phytosaurs belong to the order Phytosauria. Phytosauria and Phytosauridae are often considered to be equivalent groupings containing the same species, but some studies have identified non-phytosaurid phytosaurians. Phytosaurs were long-snouted and heavily armoured, bearing a remarkable resemblance to modern crocodilians in size, appearance, and lifestyle, as an example of convergence or parallel evolution. The name "phytosaur" means "plant reptile", as the first fossils of phytosaurs were mistakenly thought to belong to plant eaters. The name is misleading because the sharp teeth in phytosaur jaws clearly show that they were predators. For many years, phytosaurs were considered to be the most basal group of Pseudosuchia (crocodile-line archosaurs), meaning that they were thought to be more closely related to the crocodilians than to birds (the other ...

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.

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 ...

Smilosuchus Adamanensis
''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.

Rutiodon
''Rutiodon'' ("Wrinkle tooth") is an extinct genus of phytosaur belonging to the family Parasuchidae. It lived during the Late Triassic period, and was about in length. ''Rutiodon'' is known from the eastern United States (North Carolina, New Jersey, and Pennsylvania). Description Like other phytosaurs, ''Rutiodon'' strongly resembled a crocodile, but its nostrils were positioned far back on the head, close to the eyes, instead of at the tip of the snout. It had enlarged front teeth, and a relatively narrow jaw, somewhat resembling that of a modern gharial. This suggests that this carnivore probably caught fish and it may also have snatched land animals from the waterside. Also, like modern crocodiles, its back, flanks, and tail were covered with bony armored plates. ''Rutiodon'' was among the largest carnivorous animals of its environment, measuring 3–8 meters (10–26 ft) in length. Species The type species of ''Rutiodon'' is ''R. carolinensis''.

Phytosauridae
Parasuchidae is a clade of phytosaurs more derived than ''Diandongosuchus'', a basal phytosaur. It encompasses nearly all phytosaurs, include early ''Parasuchus''-grade forms as well as a more restricted clade of more specialized phytosaurs. This more restricted clade is traditionally known as the family Phytosauridae and more recently as the subfamily Mystriosuchinae. Parasuchids have been recovered from Late Triassic deposits in Europe, North America, India, Morocco, Thailand, Brazil, Greenland and Madagascar. In their osteology of ''Parasuchus'', Kammerer et al. (2016) suggested using Parasuchidae to include taxa traditionally included in Phytosauridae as well as ''Parasuchus''-grade taxa. Stocker et al. (2017) use the phytosaur classification advocated by Kammerer et al. (2016) by recovering ''Diandongosuchus ''Diandongosuchus'' is an extinct genus of archosauriform reptile, possibly a member of the Phytosauria, known from the Middle Triassic of China.
