Therocephalia
Therocephalia is an extinct suborder of eutheriodont therapsids (mammals and their close relatives) from the Permian and Triassic. The therocephalians ("beast-heads") are named after their large skulls, which, along with the structure of their teeth, suggest that they were carnivores. Like other non-mammalian synapsids, therocephalians were once described as "mammal-like reptiles". Therocephalia is the group most closely related to the cynodonts, which gave rise to the mammals. This relationship takes evidence in a variety of skeletal features. The fossils of therocephalians are numerous in the Karoo of South Africa, but have also been found in Russia, China, Tanzania, Zambia, and Antarctica. Early therocephalian fossils discovered in Middle Permian deposits of South Africa support a Gondwanan origin for the group, which seems to have spread quickly across Earth. Although almost every therocephalian lineage ended during the great Permian–Triassic extinction event, a few represe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Baurioids
Baurioidea is a superfamily of therocephalian therapsids. It includes advanced therocephalians such as '' Regisaurus'' and ''Bauria''. The superfamily was named by South African paleontologist Robert Broom in 1911. Bauriamorpha, named by D. M. S. Watson and Alfred Romer in 1956, is a junior synonym of Baurioidea. Many baurioids were once placed in a group called Scaloposauria. Scaloposaurs were characterized by their small size and reduced postorbital bar (a strut of bone behind the eye socket). Scaloposauria is no longer recognized as a valid taxon because it likely represents juvenile forms of many groups of therocephalians. Most scaloposaurs, including ''Scaloposaurus'' and ''Regisaurus'', are now classified in various positions within Bauroidea. Many therocephalians once classified as scaloposaurians are now considered basal baurioids. The classification of these species is uncertain, as there have been no comprehensive phylogenetic analyses of scaloposaurian taxa. The val ...

Ictidosuchoides
''Ictidosuchoides'' is an extinct genus of ictidosuchid therocephalians. Fossils have been found from the Karoo Basin in South Africa. The genus is known to have been one of the few therocephalians to have survived the Permian-Triassic extinction event in this area, although its numbers were quite low after the extinction.Ward, P.

Chlynovia
''Chlynovia'' is an extinct genus of therocephalian therapsids from the Late Permian of Russia. The type species is ''C. serridentatus'', named in 2000. ''Chlynovia'' was originally classified within Scaloposauria, a group of therocephalians characterized by their small size and lightly built skulls. Scaloposaurians are no longer recognized as a true grouping, but instead represent the juvenile forms of many types of therocephalians. ''Chlynovia'' was placed in the family Perplexisauridae along with ''Perplexisaurus'', but both therocephalians are now placed in the family Ictidosuchidae. ''Chlynovia'' was found in the Urpalov Formation in the Kirov region of Russia. Remains of ''Chlynovia'' have been found alongside pareiasaurs and therapsid Therapsida is a major group of eupelycosaurian synapsids that includes mammals, their ancestors and relatives.

Global Biodiversity Information Facility
The Global Biodiversity Information Facility (GBIF) is an international organisation that focuses on making scientific data on biodiversity available via the Internet using web services. The data are provided by many institutions from around the world; GBIF's information architecture makes these data accessible and searchable through a single portal. Data available through the GBIF portal are primarily distribution data on plants, animals, fungi, and microbes for the world, and scientific names data. The mission of the GBIF is to facilitate free and open access to biodiversity data worldwide to underpin sustainable development. Priorities, with an emphasis on promoting participation and working through partners, include mobilising biodiversity data, developing protocols and standards to ensure scientific integrity and interoperability, building an informatics architecture to allow the interlinking of diverse data types from disparate sources, promoting capacity building and cat ...

Therapsid
Therapsida is a major group of eupelycosaurian synapsids that includes mammals, their ancestors and relatives. Many of the traits today seen as unique to mammals had their origin within early therapsids, including limbs that were oriented more underneath the body, as opposed to the sprawling posture of many reptiles and salamanders. Therapsids evolved from "pelycosaurs", specifically within the Sphenacodontia, more than 279.5 million years ago. They replaced the "pelycosaurs" as the dominant large land animals in the Middle Permian through to the Early Triassic. In the aftermath of the Permian–Triassic extinction event, therapsids declined in relative importance to the rapidly diversifying reptiles during the Middle Triassic. The therapsids include the cynodonts, the group that gave rise to mammals ( Mammaliaformes) in the Late Triassic, around 225 million years ago. Of the non-mammalian therapsids, only cynodonts survived beyond the end of the Triassic, with the only other ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Early Triassic
The Early Triassic is the first of three epochs of the Triassic Period of the geologic timescale. It spans the time between Ma and Ma (million years ago). Rocks from this epoch are collectively known as the Lower Triassic Series, which is a unit in chronostratigraphy. The Early Triassic is the oldest epoch of the Mesozoic Era. It is preceded by the Lopingian Epoch (late Permian, Paleozoic Era) and followed by the Middle Triassic Epoch. The Early Triassic is divided into the Induan and Olenekian ages. The Induan is subdivided into the Griesbachian and Dienerian subages and the Olenekian is subdivided into the Smithian and Spathian subages. The Lower Triassic series is coeval with the Scythian Stage, which is today not included in the official timescales but can be found in older literature. In Europe, most of the Lower Triassic is composed of Buntsandstein, a lithostratigraphic unit of continental red beds. The Early Triassic and partly also the Middle Triassic span the in ...
