Hyperodapedontinae
Hyperodapedontinae is a subfamily of rhynchosaurs within the family Hyperodapedontidae. Fossils have been found from Argentina, Brazil, Canada, India, Madagascar, Scotland, Tanzania, United States and Zimbabwe. Phylogeny Hyperodapedontinae was erected by Sankar Chatterjee in 1969 as a coordinate name of the family Hyperodapedontidae Lydekker, 1985. Chatterjee (1969) originally named Hyperodapedontinae to include all Late Triassic rhynchosaurs known at that time, ''H. gordoni'', ''H. huxleyi'' and ''"Scaphonyx" fischeri'', and proposed a morphological diagnosis for the clade. ''Scaphonyx'' includes two additional species, ''S. africanus'' and ''S. australis'', all of which are currently believed to be dubious. As noted by Langer ''et al.'' (2000), using Chatterjee' morphological definition would exclude ''Teyumbaita'' and ''H. huenei'' from the clade, and thus it would be nested within ''Hyperodapedon''. To preserve the name, with its original stratigraphical meaning, Langer ''et a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scaphonyx
''Hyperodapedon'' is a genus of rhynchosaurs (beaked, archosaur-like reptiles) from the Late Triassic period (Carnian stage). Fossils of the genus have been found in Africa, Asia, Europe and North and South America. Its first discovery and naming was found by Thomas Henry Huxley in 1859. ''Hyperodapedon'' was a herbivore that used its beaked premaxilla and hindlimbs to dig for plants in dry land. Description ''Hyperodapedon'' was a heavily built, stocky, animal. ''H. gordoni'' had total length around with skull length of to , but largest species, ''H. huxleyi'' had lower jaw about and skull length is estimated about . Apart from its beak, it had several rows of heavy teeth on each side of the upper jaw, and a single row on each side of the lower jaw, creating a powerful chopping action when it ate. It is believed to have been herbivorous, feeding mainly on seed ferns, and died out when these plants became extinct at the end of the Triassic. The diagnosis of ''Hyperodapedon ...

Rhynchosaur
Rhynchosaurs are a group of extinct herbivorous Triassic archosauromorph reptiles, belonging to the order Rhynchosauria. Members of the group are distinguished by their triangular skulls and elongated, beak like premaxillary bones. Rhynchosaurs first appeared in the Middle Triassic or possibly the Early Triassic, before becoming abundant and globally distributed during the Carnian stage of the Late Triassic. Description Rhynchosaurs were herbivores, and at times abundant (in some fossil localities accounting for 40 to 60% of specimens found), with stocky bodies and a powerful beak. Early primitive forms, like ''Mesosuchus'' and '' Howesia'', were generally small and more typically lizard-like in build, and had skulls rather similar to the early diapsid ''Youngina'', except for the beak and a few other features. Later and more advanced genera grew to medium to medium large size, up to two meters in length. The skull in these forms were short, broad, and triangular, becoming muc ...

Teyumbaita Sulcognathus
''Teyumbaita'' is an extinct genus of hyperodapedontine rhynchosaur from the Upper Triassic of southern Brazil. Its fossils were recovered from the early Norian-age Caturrita Formation, one of several fossiliferous formations exposed at Paleorrota Geopark in the state of Rio Grande do Sul. ''Teyumbaita'' is likely the youngest valid genus of rhynchosaur, as other members of the group likely died out before the start of the Norian. Fossils of ''Teyumbaita'' include two nearly complete skulls and a partial skull, all of which were discovered in the lower part of the Caturrita Formation. The fossils were first named as ''Scaphonyx sulcognathus'', a species of ''Scaphonyx''. The genus ''Scaphonyx'' is now considered to be a ''nomen dubium'', so ''S. sulcognathus'' was reassigned to its own genus by Felipe Chinaglia Montefeltro, Max Cardoso Langer and Cesar Leandro Schultz in 2010. This new genus name, ''Teyumbaita'', was constructed from "lizard (''teyú'') and parrot ''(mbaitá'')" ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Isalorhynchus
''Isalorhynchus'' is an extinct genus of hyperodapedontine rhynchosaur from the late Triassic period (Carnian stage) of Toliara Province, southwestern Madagascar. It is known from the holotype MDE-R18, a nearly complete maxilla and from other specimens from the same locality, Malio River area. It was found in the Makay Formation (or Isalo II) of the Morondava Basin (or Isalo beds). It was first named by Eric Buffetaut in 1983 and the type species is ''Isalorhynchus genovefae''.

Oryctorhynchus
''Oryctorhynchus'' is an extinct genus of rhynchosaur from the Late Triassic (Carnian-Norian)-aged Wolfville Formation of Nova Scotia, Canada. The type species, ''O. bairdi'', was named and described in 2020. It was originally seen as a species of ''Hyperodapedon'' until 2020. Discovery and naming The holotype was discovered in the Wolfville Formation; its earliest known mention is by Baird (1963). Shortly after, it was informally named the "Nova Scotia ''Hyperodapedon''" (''H''. sp.) by Robin Whatley. It was briefly described by Michael Benton (1983) also as a species of ''Hyperodapedon''.Benton, M.J. 1983. The Triassic reptile ''Hyperodapedon'' from Elgin: functional morphology and relationships. ''Philosophical Transactions of the Royal Society of London'' B 302: 605-717. The genus was not recognised as a distinct taxon until it was named in 2020.

Supradapedon
''Supradapedon'' is an extinct genus of hyperodapedontine rhynchosaur from mid-late Triassic deposits of Tanganyika Territory, Tanzania. It is known from the holotype SAM-11704. The holotype and only specimen of ''Supradapedon'' was first assigned to a species of ''Scaphonyx'' (now considered to be a ''nomen dubium''), ''Scaphonyx stockleyi''. This species was reassigned to its own genus by Sankar Chatterjee in 1980 and the type species is ''Supradapedon stockleyi''. One study, Langer ''et al.''

Fodonyx
''Fodonyx'' (meaning "digging claw") is an extinct genus of rhynchosaur from the middle Triassic epoch of Devon in England. Its fossils (25 specimens) were discovered in Otter Sandstone Formation (late Anisian age) and were first assigned to '' Rhynchosaurus spenceri''. This species was reassigned to its own genus, ''Fodonyx'' (the type and only species is ''Fodonyx spenceri'') the holotype of which iEXEMS 60/1985/292, that described by David W. E. Hone and Michael J. Benton in 2008. More recently, one skull was reassigned to the new genus ''Bentonyx''. It is distinguished from other rhynchosaurs by a single autapomorphy, the ventral angling of the paraoccipital processes. In all other rhynchosaurs these processes angle dorsally or are horizontal. It is not known if this conferred any advantage to ''Fodonyx. Fodonyx'' was between 40 and 50 cm long. Features Skull and lower jaw The two premaxillae are very long and run up over the snout to meet the prefrontals at the or ...

Wolfville
Wolfville is a Canadian town in the Annapolis Valley, Kings County, Nova Scotia, located about northwest of the provincial capital, Halifax. The town is home to Acadia University and Landmark East School. The town is a tourist destination due to its views of Cape Blomidon, the Bay of Fundy and Gaspereau Valley, as well as its wine industry. The downtown portion of Wolfville is home to pubs, bars, cafes and shops. Wolfville is also home to the Acadia Cinema Cooperative, a non-profit organization that runs the local movie/performance house. In the past few years, several Victorian houses in Wolfville have been converted to bed and breakfast establishments. History First Nations From ancient times, the area of Wolfville was a hunting ground for First Nations peoples, including the Clovis, Laurentian, Bear River, and Shields Archaic groups. They were attracted by the salmon in the Gaspereau River and the agate stone at Cape Blomidon, with which they could make stone tools. Ma ...
