Daqingshanodon
''Daqingshanodon'' is an extinct genus of dicynodont therapsid from the Late Permian of Inner Mongolia, China. The type species ''D. limbus'' was described in 1989 from a single skull found in the Naobaogou Formation. ''Daqingshanodon'' belongs to a group of dicynodonts called cryptodonts. It is the smallest known cryptodont, and the only one known from China. Like other cryptodonts, it has a pair of rounded nasal bosses above its nostrils and a ridge of bone on the upper jaw called the postcaniniform process. ''Daqingshanodon'' has a pair of elongated, recurved tusks extending from its beak-like snout. It is distinguished from other dicynodonts by the presence of a distinct ridge running along the side of the skull from below the eye socket to the area around the tusks. The skull of ''Daqingshanodon'' is less than long, yet this specimen is thought to have been an adult on the basis of its well-developed nasal bosses. In his 1998 study of dicynodont biogeography, paleontologi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Naobaogou Formation
The Naobaogou Formation is a geological formation in the Daqing Mountains of China. It is likely of Lopingian age. It consists of three rhythms of sediment, labelled members I-III primarily of purple siltstone Siltstone, also known as aleurolite, is a clastic sedimentary rock that is composed mostly of silt. It is a form of mudrock with a low clay mineral content, which can be distinguished from shale by its lack of fissility.Blatt ''et al.'' 1980, ..., but each with a thick basal conglomerate bed. It is notable for its fossil content, producing one of the most diverse Late Permian vertebrate faunas outside Russia and South Africa.

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 sk ...

Dicynodon
''Dicynodon'' ("two dog-teeth") is a genus of dicynodont therapsid that flourished during the Upper Permian period. Like all dicynodonts, it was herbivorous animal. This reptile was toothless, except for prominent tusks, hence the name. It probably cropped vegetation with a horny beak, much like a tortoise, while the tusks may have been used for digging up roots and tubers. Many species of ''Dicynodon'' have been named, and the genus is considered a wastebasket taxon. A 2011 study of the genus found most of the species to represent a paraphyletic grouping, with the only valid members of ''Dicynodon'' being ''D. lacerticeps'' and ''D. huenei''. A 2019 study named a new species ''D. angielczyki'', but simultaneously transferred ''D. huenei'' to the genus '' Daptocephalus''. Description ''Dicynodon'' was a medium-sized and advanced member of the Dicynodont group. It had an average length of , although size differed among species. Its fossil remains have been found in sediments o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

''Odontocyclops'' : Greek: “tooth” Greek: “round eye”, a kind of Greek mythological giant with one eye in the midline =toothy cyclops. The ''Odontocyclops'' is an extinct genus of Dicynodonts that lived in the Late Permian. Dicynodonts are believed to be the first major assemblage of terrestrial herbivores.Angielczyk, K. D. 2002.

Fossils of ''Odontocyclops'' have been found in the Karoo Basin of South Africa and the Luangwa Valley of Zambia. The phylogenetic classification of ''Odontocyclops'' has been long under debate, but most current research places them as their own genus of Dicynodonts and being very closely related to ''Rhachiocephalus'' and ''Oudenodon''.

Geikiidae
Geikiidae is a family of Late Permian dicynodonts. Fossils are known from Scotland, South Africa, and Tanzania. The family was first named by Franz Nopcsa in 1923, although Friedrich von Huene's 1948 description of the family brought it into common usage. Von Huene established Geikiidae as a monotypic family for ''Geikia'', then known from Scotland. He distinguished ''Geikia'' from all other dicynodonts because it lacked a preparietal bone. The outlines on the bones of the skull roof could not be seen however, meaning that this characteristic was uncertain in geikiids. Geikiids were originally classified as close relatives of ''Dicynodon'' and ''Lystrosaurus ''Lystrosaurus'' (; 'shovel lizard'; proper Greek is λίστρον ''lístron'' ‘tool for leveling or smoothing, shovel, spade, hoe’) is an extinct genus of herbivorous dicynodont therapsids from the late Permian and Early Triassic epochs ( ...'', but the characters that linked these dicynodonts are also seen in many ...
