Rutiodon Manhattanensis Holotype
''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''. A second species, ''R. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 herbivorous. ...

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 ...

Angistorhinus
''Angistorhinus'' (meaning "narrow snout" or "hook snout") is an extinct genus of phytosaur known from the Late Triassic period of Texas and Wyoming, United States. It was first named by Mehl in 1913 and the type species is ''Angistorhinus grandis''. Other species from Texas and Wyoming, ''A. alticephalus'' (Stovall and Wharton, 1936), ''A. gracilis'' (Mehl, 1915) and ''A. maximus'' (Mehl, 1928), are cospecific with the type species. ''Angistorhinus'' is known from the holotype UC 631, partial skull and lower jaws recovered from the Popo Agie Formation, Chugwater Group, Wyoming and from the associated paratype UM 531, a partial skull, TMM 31098-1, skull and lower jaws and ROM 7977, partial skull and lower jaws, recovered from the 'Pre-Tecovas Horizon' in the Dockum Group, Texas. A possible second species, ''A. talainti'' is known from the Triassic of Morocco. In 1995, Long and Murry created the new combination, ''Angistorhinus megalodon'' by synonymy for ''Brachysuchus''.

Brachysuchus Megalodon
''Brachysuchus'' (meaning "wide crocodile") is an extinct genus of phytosaur known from the late Triassic period ( Carnian stage) of Dockum Group in Texas, United States. It is known from the holotype UMMP 10336 is composed of a skull, lower jaws and partial postcranium and from the associated paratype UMMP 14366, nearly complete skull, recovered from the 'Pre-Tecovas Horizon' in the Dockum Group. It was first named by Case in 1929 and the type species is ''Brachysuchus megalodon''. Its closest relative was ''Angistorhinus''. However, its rostral crest was much smaller than that of ''Angistorhinus,'' and the rostrum as a whole is shorter and thicker. Features The lower jaws of ''Brachysuchus'' are expanded at the tip to form a large bulge, holding the creature's largest tusks. The surface of this part of the bone has a wrinkled look, with many blood vessels running through it. In the lower jaw, there are three tusks in each side of this protuberance. Behind this part the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

Paleorhinus Bransoni
''Paleorhinus'' (Greek: ''"Old Nose"'') is an extinct genus of widespread 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 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 lump all basal phytosaurs into only one or two genera, rendering those genera paraphyletic evolutionary grades ancestral to later phytosaurs. More recently, these grades have been broken up into multiple genera. '' Arganarhinus ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Phytosauria
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 othe ...

Cladogram
A cladogram (from Greek ''clados'' "branch" and ''gramma'' "character") is a diagram used in cladistics to show relations among organisms. A cladogram is not, however, an evolutionary tree because it does not show how ancestors are related to descendants, nor does it show how much they have changed, so many differing evolutionary trees can be consistent with the same cladogram. A cladogram uses lines that branch off in different directions ending at a clade, a group of organisms with a last common ancestor. There are many shapes of cladograms but they all have lines that branch off from other lines. The lines can be traced back to where they branch off. These branching off points represent a hypothetical ancestor (not an actual entity) which can be inferred to exhibit the traits shared among the terminal taxa above it. This hypothetical ancestor might then provide clues about the order of evolution of various features, adaptation, and other evolutionary narratives about ance ...
