Belodon
''Belodon'' (meaning "arrow tooth") is a genus of phytosaur, a crocodile-like reptile that lived during the Triassic. Its fossils have been found in Europe, North American, and India, but their remains have not been found in the southern continents. Familiar genera include Phytosaurus, Belodon, and Rutiodon, which was more than 3 metres (10 feet) long and whose skull alone measured about 1 metre. The type species, ''Belodon plieningeri'', was named by prolific German paleontologist Christian Erich Hermann von Meyer in 1844. Many other species were also named, among them ''Belodon buceros'' (named by Edward Drinker Cope in 1881),Cope, E.D. (1881). "''Belodon'' in New Mexico". ''American Naturalist'' 15: 922-923. ''Belodon kapfii'' (von Meyer, 1861), ''Belodon lepturus'' (Cope, 1870),Cope, E.D. (1870). "Reptilia of the Triassic Formation of the United States". ''American Naturalist'' 4: 562-563.

Phytosaur
Phytosaurs (Φυτόσαυροι in Greek, meaning 'plant lizard') are an extinct group of large, mostly semiaquatic Late Triassic archosauriform or basal archosaurian reptiles. Phytosaurs belong to the order Phytosauria and are sometimes referred to as parasuchians. Phytosauria, Parasuchia, Parasuchidae, and Phytosauridae have often been considered equivalent groupings containing the same species. Some recent studies have offered a more nuanced approach, defining Parasuchidae and Phytosauridae as nested clades within Phytosauria as a whole. The clade Phytosauria was defined by Paul Sereno in 2005 as '' Rutiodon carolinensis'' and all taxa more closely related to it than to '' Aetosaurus ferratus'', '' Rauisuchus tiradentes'', '' Prestosuchus chiniquensis'', '' Ornithosuchus woodwardi'', or '' Crocodylus niloticus'' (the Nile crocodile). Phytosaurs were long-snouted and heavily armoured, bearing a remarkable resemblance to modern crocodilians in size, appearance, and lifesty ...

Phytosauria
Phytosaurs (Φυτόσαυροι in greek language, Greek, meaning 'plant lizard') are an extinct group of large, mostly semiaquatic Late Triassic archosauriform or Basal (phylogenetics), basal archosaurian reptiles.

Phytosauria, Parasuchia, Parasuchidae, and Phytosauridae have often been considered equivalent groupings containing the same species.

Machaeroprosopus
''Machaeroprosopus'' (from , 'large knife' and , 'bordering on') 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nicrosaurus
''Nicrosaurus'' (/nɪkroʊˈsɔrəs/) 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 (much like modern-day cetaceans (ie: whales, dolphins, porpoises)), 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.

Triassic
The Triassic ( ; sometimes symbolized 🝈) is a geologic period and system which spans 50.5 million years from the end of the Permian Period 251.902 million years ago ( Mya), to the beginning of the Jurassic Period 201.4 Mya. The Triassic is the first and shortest period of the Mesozoic Era and the seventh period of the Phanerozoic Eon. 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. ''Phytosaurus'' was the first phytosaur to be described, being done so by Georg Friedrich von Jaeger in 1828.G. F. Jaeger. (1828). Über die Fossile Reptilien, Welche in Württemberg Aufgefunden Sind n the Fossil Reptiles That Are Found in Württemberg ''Verlag der Metzler'schen Buchhandlung, Stuttgart'' 1-48 The type species is ''P. cylindricodon'' and a second species, ''P. cubicodon'', is also known. Discovery and naming In 1826, the holotypes of both species were discovered in Wurttemburg, Germany at the "Neckar" site at the base of the hill which Wildenau Castle stands upon. The holotype of ''P. cylindricodon'' consists of parts of the skull and jaws, with natural casts of the teeth which, however, did not preserve their conical form but were flattened which led to the misunderstanding they were spe ...

Prehistoric Reptile Genera
Prehistory, also called pre-literary history, is the period of human history between the first known use of stone tools by hominins 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 years ago. It took thousands of years for writing systems to be widely adopted, with writing having spread to almost all cultures by the 19th century. The end of prehistory therefore came at different times in different places, and the term is less often used in discussing societies where prehistory ended relatively recently. It is based on an old conception of history that without written records there could be no history. The most common conception today is that history is based on evidence, however the concept of prehistory hasn't been completely discarded. In the early Bronze Age, Sumer in Mesopotamia, the Indus Valley Civilis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Edward Drinker Cope
Edward Drinker Cope (July 28, 1840 – April 12, 1897) was an American zoologist, paleontology, paleontologist, comparative anatomy, comparative anatomist, herpetology, herpetologist, and ichthyology, ichthyologist. Born to a wealthy Quaker family, he distinguished himself as a child prodigy interested in science, publishing his first scientific paper at the age of 19. Though his father tried to raise Cope as a gentleman farmer, he eventually acquiesced to his son's scientific aspirations. Cope had little formal scientific training, and he eschewed a teaching position for field work. He made regular trips to the Western United States, American West, prospecting in the 1870s and 1880s, often as a member of United States Geological Survey, U.S. Geological Survey teams. A personal feud between Cope and paleontologist Othniel Charles Marsh led to a period of intense fossil-finding competition now known as the Bone Wars. Cope's financial fortunes soured after failed mining ventures i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
