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 ...

Bulbasaurus
''Bulbasaurus'' (meaning "bulbous reptile") is an extinct genus of dicynodont that is known from the Lopingian epoch of the Late Permian period of what is now South Africa, containing the type and only species ''B. phylloxyron''. It was formerly considered as belonging to '' Tropidostoma''; however, due to numerous differences from ''Tropidostoma'' in terms of skull morphology and size, it has been reclassified the earliest known member of the family Geikiidae, and the only member of the group known from the ''Tropidostoma'' Assemblage Zone. Within the Geikiidae, it has been placed close to '' Aulacocephalodon'', although a more basal position is not implausible. ''Bulbasaurus'' was ostensibly not directly named after the Pokémon Bulbasaur, but rather after its nasal bosses, which are unusually bulbous among geikiids; however, the describers noted that the similarity in name "may not be entirely coincidental." Additionally, the specific name of the type species means "leaf ra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dicynodonts
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 ...

Aulacephalodon
''Aulacephalodon'' is an extinct genus of medium-sized dicynodonts, or non-mammalian synapsids, that lived during Permian period, about 299-252 million years ago. Individuals of ''Aulacephalodon'' are commonly found in the Lower Beaufort Group of the Karoo Supergroup of South Africa and Zambia. Rising to dominance during the Late Permian, ''Aulacephalodon'' were the dominant terrestrial vertebrate herbivores until they became extinct during the Triassic. No living relatives of ''Aulacephalodon'' exist today. Two species have been named, the type species, ''A. bainii,'' and a second species, ''A. peavoti''. However, debate exists among paleontologists if ''A. peavoti'' is a true member of the genus ''Aulacephalodon''. Therefore, a majority of the information known about ''Aulacephalodon'' is in reference to discoveries about ''A. bainii''. The name ''Aulacephalodon'' combines the Greek words aulak- (aulax), meaning "a furrow", kephale, meaning "head," and odon, meaning tooth. Toge ...

Geikia
''Geikia'' is an extinct genus of dicynodont therapsids from the late Permian. The abundance and diversity of dicynodonts during this period, combined with incomplete or inadequately prepared specimens, have led to challenges in determining relationships within this taxon. Only two species, ''Geikia locusticeps'' and ''Geikia elginensis'' have been assigned to this genus. While this is the currently accepted classification, fossil record limitations have led to repeated debate on the genus assignments of these species. Description A high level of skull specialization was significant in the classification of ''Geikia''. Maisch and Gebauer considered the squared off anterior snout tip and reduced exposure of squamosal in occiput to be characteristics exclusively expressed in ''Geikia''. Prior to their analysis, Rowe described the generic diagnosis of Geikia as “dicynodonts having no tusk or postcanine teeth; highly vaulted palate; anterior palatal ridges of premaxilla reduced or ...

Pelanomodon
''Pelanomodon'' is an extinct genus of dicynodont therapsids that lived in the Late Permian period. Fossil evidence of this genus is principally found in the Karoo Basin of South Africa, in the ''Dicynodon'' Assemblage Zone.Kammerer, C. F., K. D. Angielczyk, and Jörg Fröbisch. 2015. Redescription of the geikiid Pelanomodon (Therapsida, Dicynodontia), with a reconsideration of ‘Propelanomodon’. Journal of Vertebrate Paleontology. DOI: 10.1080/02724634.2015.1030408. http://www.tandfonline.com/doi/full/10.1080/02724634.2015.1030408 Lack of fossil record after the Late Permian epoch suggests that ''Pelanomodon'' fell victim to the Permian-Triassic extinction event. The name ''Pelanomodon'' can be broken up into three parts; “pelos” meaning mud, “anomo” meaning irregular and “odon” meaning tooth. Together, this suggests ''Pelanomodon'' to be a mud dwelling anomodont (a group of therapsids that are characterized by their lack of teeth). The Karoo Basin during this pe ...

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 (around 250 million years ago). It lived in what is now Antarctica, India, China, Mongolia, European Russia and South Africa. Four to six species are currently recognized, although from the 1930s to 1970s the number of species was thought to be much higher. They ranged in size from that of a small dog to 8 feet (2.5 meters) long. As a dicynodont, ''Lystrosaurus'' had only two teeth (a pair of tusk-like canines), and is thought to have had a horny beak that was used for biting off pieces of vegetation. ''Lystrosaurus'' was a heavily built, herbivorous animal, approximately the size of a pig. The structure of its shoulders and hip joints suggests that ''Lystrosaurus'' moved with a semi-sprawling gait. The forelimbs were even more robust th ...

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] |
Monotypic
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, '' Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda. ...
