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
''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 jaws ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phytosaur
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 ...

Parasuchus
''Parasuchus'' is an extinct genus of basal phytosaur known from the Late Triassic (late Carnian to early Norian stage) of Andhra Pradesh and Madhya Pradesh, India. At its most restricted definition, ''Parasuchus'' contains a single species, ''Parasuchus hislopi''. ''Parasuchus hislopi'' is one of several species belonging to a basal grade of phytosaurs, typified by the genus '' Paleorhinus''. Historically, ''Paleorhinus'' has been known from better-described fossils, and many species have been lumped into that genus. ''Parasuchus hislopi'', despite being described earlier than ''Paleorhinus'', was considered an undiagnostic chimera until new neotype fossils were described in the late 1970s. ''Parasuchus hislopi'' and the two unambiguously valid species of ''Paleorhinus'' (''P. bransoni'' and ''P. angustifrons'') are all closely related; some authors have historically described them all under the species ''Paleorhinus'', while others place the two ''Paleorhinus'' species into ' ...

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''. A second species, ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type Species
In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen(s). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name that has that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have such types.

Prehistoric Reptile Genera
Prehistory, also known as pre-literary history, is the period of human history between the use of the first stone tools by hominins 3.3 million years ago and the beginning of recorded history with the invention of writing systems. The use of symbols, marks, and images appears very early among humans, but the earliest known writing systems appeared 5000 years ago. It took thousands of years for writing systems to be widely adopted, with writing spreading to almost all cultures by the 19th century. The end of prehistory therefore came at very different times in different places, and the term is less often used in discussing societies where prehistory ended relatively recently. In the early Bronze Age, Sumer in Mesopotamia, the Indus Valley Civilisation, and ancient Egypt were the first civilizations to develop their own scripts and to keep historical records, with their neighbors following. Most other civilizations reached the end of prehistory during the following Iron Age. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Triassic
The Triassic ( ) is a geologic period and system which spans 50.6 million years from the end of the Permian Period 251.902 million years ago ( Mya), to the beginning of the Jurassic Period 201.36 Mya. The Triassic is the first and shortest period of the Mesozoic Era. Both the start and end of the period are marked by major extinction events. The Triassic Period is subdivided into three epochs: Early Triassic, Middle Triassic and Late Triassic. The Triassic began in the wake of the Permian–Triassic extinction event, which left the Earth's biosphere impoverished; it was well into the middle of the Triassic before life recovered its former diversity. Three categories of organisms can be distinguished in the Triassic record: survivors from the extinction event, new groups that flourished briefly, and other new groups that went on to dominate the Mesozoic Era. Reptiles, especially archosaurs, were the chief terrestrial vertebrates during this time. A specialized subgroup of archo ...
