Brithopus Priscus1DB
''Brithopus'' is an extinct genus of dinocephalian therapsids. It contains a single species, ''Brithopus priscus'', known from fragmentary remains found in the Copper Sandstones near Isheevo, Russia. Description ''Brithopus'' was fairly large, reaching a length of 2.5–3 m (8–10 ft). The skull was similar to ''Titanophoneus'', but more massive and heavily built.Olson, E.C. (1962). " Late Permian terrestrial vertebrates, U.S.A. and U.S.S.R." ''Transactions of the American Philosophical Society'', New Series, 52: 1–224. Classification ''B. priscus'' was first named in 1838 and was traditionally classified in the Anteosauria, a group of carnivorous dinocephalians. ''Brithopus'' served as the basis for the family Brithopodidae, which once included many anteosaurian species. Because it is based on fragmentary material, ''Brithopus'' is regarded as a ''nomen dubium In binomial nomenclature, a ''nomen dubium'' (Latin for "doubtful name", plural ''nomina dubia'') is a sc ...

Middle Permian
The Guadalupian is the second and middle series/ epoch of the Permian. The Guadalupian was preceded by the Cisuralian and followed by the Lopingian. It is named after the Guadalupe Mountains of New Mexico and Texas, and dates between 272.95 ± 0.5 – 259.1 ± 0.4 Mya. The series saw the rise of the therapsids, a minor extinction event called Olson's Extinction and a significant mass extinction called the end-Capitanian extinction event. The Guadalupian was previously known as the Middle Permian. Name and background The Guadalupian is the second and middle series or epoch of the Permian. Previously called Middle Permian, the name of this epoch is part of a revision of Permian stratigraphy for standard global correlation. The name "Guadalupian" was first proposed in the early 1900s, and approved by the International Subcommission on Permian Stratigraphy in 1996. References to the Middle Permian still exist. The Guadalupian was preceded by the Cisuralian and followed by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Estemmenosuchid
Estemmenosuchidae is an extinct family of large, very early herbivorous therapsids that flourished during the Guadalupian period. They are distinguished by horn-like structures, probably for display or agonistic behavior. Apart from the best known genus, ''Estemmenosuchus'', the group is poorly known. To date, their fossils are known only from the Perm region of Russia (a region referred to by Russian paleontologists as the Cis-Urals). Description Estemmenosuchids are among the most distinctive of the Permian tetrapods. The high and massive skull is equipped with a number of horns projecting both upwards and outwards, which were probably used for intra-specific display. The incisors and canine teeth are large, but those at the side are reduced, with a serrated apex, and may have helped to break up plant material, although they were too small to be of much use. The body is large and bulky, indicating a large digestive tract for digesting volumes of plant food. The skull superficia ...

Monotypic Prehistoric Animal Genera
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 (biology), 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 (biology), order Amborellales, there is only one family (biology), family, Amborellaceae and there is only one genus, ''Amborella'', and in this genus there is ...
