Therapsida [a] is a clade comprising a major group of eupelycosaurian synapsids that includes mammals and their ancestors and close 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, resulting in a more "standing" quadrupedal posture, as opposed to the lower sprawling posture of ...
This list of therapsids is an attempt to create a comprehensive listing of all genera that have ever been included in the Therapsida excluding mammals and purely vernacular terms.
Therapsids were synapsids that began to appear in the Early Permian.They had larger temporal fenestrae (openings of the sides of the skull) than the ancestral pelycosaurs. ...
Life restoration of Ulemica. Venyukovioidea was named for Venyukovia (in turn, named for that fossil's discoverer, Russian geologist P.N. Venyukov). [5] Venyukovia itself is known only from lower jaw fragments of a single individual, [6] [7] while Otsheria is only represented by a skull, Ulemica by its skull and lower jaws, and the fragmentary Parasuminia only by its jaw tips and part of the ...
Therocephalia is an extinct clade of eutheriodont therapsids (mammals and their close relatives) from the Permian and Triassic periods. The therocephalians ("beast-heads") are named after their large skulls, which, along with the structure of their teeth, suggest that they were carnivores.
Procynosuchidae is an extinct family of therapsids which, along with Dviniidae, were the earliest cynodonts. [1] They appeared around 260 million years ago, and were most abundant during the latest Permian time (251 mya), shortly before the Permian-Triassic extinction event.
Scylacosauridae is an extinct family of therocephalian therapsids.Scylacosaurids lived during the Permian period and were among the most basal therocephalians. [3] The family was named by South African paleontologist Robert Broom in 1903. [4]
Viatkogorgon is a genus of gorgonopsian (a type of therapsid, the group that includes modern mammals) that lived during the Permian period in what is now Russia. The first fossil was found at the Kotelnich locality near the Vyatka River and was made the holotype of the new genus and species V. ivachnenkoi in 1999.
