Dicynodont
Dicynodontia is an extinct clade of anomodonts, an extinct type of non-mammalian therapsid. Dicynodonts were herbivorous animals with a pair of tusks, hence their name, which means 'two dog tooth'. Members of the group possessed a horny, typically toothless beak, unique amongst all synapsids. Dicynodonts first appeared in Southern Pangaea during the mid-Permian, ca. 270–260 million years ago, and became globally distributed and the dominant herbivorous animals in the Late Permian, ca. 260–252 Mya. They were devastated by the end-Permian Extinction that wiped out most other therapsids ca. 252 Mya. They rebounded during the Triassic but died out towards the end of that period. They were the most successful and diverse of the non-mammalian therapsids, with over 70 genera known, varying from rat-sized burrowers to elephant-sized browsers. Characteristics The dicynodont skull is highly specialised, light but strong, with the synapsid temporal openings at the rear of the skull ...

Ufudocyclops
''Ufudocyclops'' is an extinct genus of stahleckeriid dicynodont from the Middle Triassic of South Africa. It was found in the Burgersdorp Formation, part of the uppermost ''Cynognathus'' Assemblage Zone of the Beaufort Group in the Karoo Basin. The type and only known species is ''U. mukanelai''. It was a large, beaked herbivore like other Triassic dicynodonts, lacking tusks, and is mostly characterised by unique features of the skull. It is known from three specimens, two of which were previously referred to the Tanzanian dicynodont ''Angonisaurus''. The separation of ''Ufudocyclops'' from ''Angonisaurus'' indicates that the Middle Triassic fauna of the Beaufort Group in South Africa was not part of a larger shared fauna with those of the Manda Beds in Tanzania, as was previously supposed, and suggests that they were separated as more localised faunas, possibly by geographic barriers or in time. ''Ufudocyclops'' then would have been a unique part of the uppermost ''Cynognathus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kannemeyeria Simocephalus
''Kannemeyeria'' is a genus of dicynodont that lived during the Anisian age of Middle Triassic period in what is now Africa and South America. The generic name is given in honor of Dr. Daniel Rossouw Kannemeyer, the South African fossil collector who discovered the original specimen. It is one of the first representatives of the family, and hence one of the first large herbivores of the Triassic. Description ''Kannemeyeria'' was about in length, about the size of an ox. Although it had a large head, it was lightweight due to the size of the eye sockets and nasal cavity. It also had limb girdles which formed massive plates of bone that helped support its heavily built body. ''Kannemeyeria'' was well-adapted to living as a herbivore; it had a powerful beak and strong jaw muscles built for shearing plant material. ''Kannemeyeria'' had a massive head with unusually large openings for the eyes, nostrils and jaw muscles. It evidently tore up roots, stripped leaves from the vegeta ...

Lisowicia
''Lisowicia'' is an extinct genus of giant dicynodont synapsid that lived in what is now Poland during the late Norian or earliest Rhaetian age of the Late Triassic Period, about 210–205 million years ago. ''Lisowicia'' is the largest known dicynodont, as well as the largest non-mammalian synapsid, and is estimated to have weighed between 5–6 tons, comparable in size to modern elephants. It was also one of the last dicynodonts, living shortly before their extinction at the end of the Triassic period. Fossils of a giant dicynodont were known from Poland since 2008, but ''Lisowicia'' was not named and officially described as a new species until late 2018. ''Lisowicia'' is unique amongst dicynodonts for its erect posture, with all four limbs held upright directly under its body. This is similar to the limbs of living mammals and dinosaurs, but unlike the sprawling and semi-erect postures typical of all other dicynodonts (and indeed all other non-mammalian synapsids), and shares ...

Pentasaurus
''Pentasaurus'' is an extinct genus of dicynodont of the family Stahleckeriidae, closely related to the well known ''Placerias''. It was found in the Lower Elliot Formation of South Africa, dated to the Norian of the Late Triassic period. The genus contains the type and only species, ''Pentasaurus goggai''. ''Pentasaurus'' is named after the ichnogenus '' Pentasauropus'', fossil footprints that were originally described from the lower Elliot Formation in 1970 decades before the body fossils of ''Pentasaurus'' itself were recognised. ''Pentasauropus'' footprints were likely made by dicynodonts, and in South Africa ''Pentasaurus'' itself was the likely trackmaker. The name reflects the fact that a large dicynodont was predicted to have existed in the lower Elliot Formation before any body fossils were recognised, and so ''Pentasaurus'' was named after its probable footprints. This is a reversal of the more typical occurrence where fossil footprints are named after their presumed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Eubrachiosaurus
''Eubrachiosaurus'' is an extinct genus of stahleckeriid dicynodont known from the Late Triassic (Carnian stage) of Wyoming, United States. Description ''Eubrachiosaurus'' is known only from the holotype specimen Field Museum of Natural History, FMNH UC 633, a partial left scapula as well as a left humerus, and left pelvis which have been lost. It was collected at the Little Popo Agie River, near Lander, Fremont County, Wyoming, Fremont County from the Popo Agie Formation of the Chugwater Group. ''Eubrachiosaurus browni'' was first described and named by Samuel Wendell Williston in 1904 in paleontology, 1904 along with ''Brachybrachium brevipes''. Lucas and Hunt (1993) considered both taxa junior synonyms of ''Placerias hesternus'', which is known from the same formation, a position maintained in most subsequent studies. The synonymy of ''Eubrachiosaurus'' and ''Placerias'' was questioned by Long and Murry (1995) who noted that the ectepicondyle of ''Eubrachiosaurus'' was enlarg ...

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 ...

Dinodontosaurus
''Dinodontosaurus'' (meaning "terrible-toothed lizard") is a genus of dicynodont therapsid. It was medium to large dicynodont of the Triassic (with skull up to long) and had a beak corneum. It lived in the Middle Triassic but disappeared in the Upper Triassic. Species * ''Dinodontosaurus tener'' is the most common species of dicynodont that existed in the Middle Triassic, and more common in the fossil layers that age in Rio Grande do Sul, in Rota Paleontológica. They are found mainly in the Paleontological Site Chiniquá in São Pedro do Sul and Candelária, where a group of ten pups were found together, demonstrating that these animals had strategies for coexistence in a group and caring for their offspring.
