Zambiasaurus
''Zambiasaurus'' is an extinct genus of dicynodonts that was discovered in the Middle Triassic (Anisian) Ntawere Formation of Zambia, southern Africa. It was a large dicynodont, reconstructed using several fossil fragments, in majority belonging to probably a juvenile ''Zambiasaurus submersus''. ''Zambiasaurus submersus'' is the type species of the genus ''Zambiasaurus''. It is a Stahleckeriidae, stahleckeriid, the first Stahleckeriidae, stahleckeriid known outside South America, and it is also the oldest known Stahleckeriidae, stahleckeriid. Description Skull The skull of ''Zambiasaurus submersus'' was reconstructed by using eighteen different juvenile fossil fragments and fragments of an adult Zambiasaurus. The immature skull had the dimensions of long and wide while the adults had a skull long and wide. There are no teeth in both upper and lower jaws making it a herbivorous species. Skull tapers Anatomical terms of location, anteriorly, widest across Occipital bone, o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

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] |
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] |
Ischigualastia
''Ischigualastia'' is an extinct genus of large dicynodont therapsids that lived during the Late Carnian age and the Early Norian age of the Late Triassic Period. The genus was found in and named after the Ischigualasto Formation (Cancha de Bochas Member) of the Ischigualasto-Villa Unión Basin in northwestern Argentina. It has been placed in the family Stahleckeriidae. Description The genus is described as an enormous dicynodont, with a short, high skull, and lacking tusks. It is regarded as larger than its later, more famous relative ''Placerias'', which weighed over . Paleoecology It was a large quadrupedal herbivore, most common at the base of the Ischigualasto Formation. It was a common member of the local fauna, although not as abundant as the medium-sized herbivores ''Hyperodapedon'' and ''Exaeretodon''. The only danger to such a huge animal was the almost equally large carnivorous pseudosuchian ''Saurosuchus'' and perhaps the predatory dinosaur ''Herrerasaurus'', ...

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 ...

Kannemeyeria Lophorhinus
''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 ...

Sangusaurus
''Sangusaurus'' is an extinct genus of large dicynodont synapsid with two recognized species: ''S. edentatus'' (the type species) and ''S. parringtonii''. ''Sangusaurus'' is named after the Sangu stream in eastern Zambia near to where it was first discovered + ‘saur’ which is the Greek root for lizard. ''Sangusaurus'' fossils have been recovered from the upper parts of the Ntawere Formation in Zambia and of the Lifua Member of the Manda Beds in Tanzania. The earliest study considered ''Sangusaurus'' a kannemeyeriid dicynodont, but more recent phylogenetic analyses place ''Sangusaurus'' within the stahleckeriid clade of Dicynodontia. Until recently, little work had been done to describe ''Sangusaurus'', likely due to the fact that only four incomplete fossil specimens have been discovered. Discovery The first ''Sangusaurus'' fossil was found in 1963 during a joint paleontological expedition of the British Museum (Natural History) and the University of London. Cox first named ...

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.
