Burnetiamorphs
Burnetiamorpha is a clade of biarmosuchian therapsids. Burnetiamorphs are the most derived biarmosuchians. The name Burnetiamorpha has been in use since South African paleontologist Robert Broom erected the group in 1923, but it has recently been put to use in phylogenetic classification as a clade including Burnetiidae and its closest relatives, including ''Lemurosaurus'', '' Lophorhinus'', and '' Lobalopex''.

Paraburnetia
''Paraburnetia'' is an extinct genus of biarmosuchian therapsids from the Late Permian of South Africa. It is known for its species ''P. sneeubergensis'' and belongs to the family Burnetiidae. ''Paraburnetia'' lived just before the Permian–Triassic mass extinction event. The etymology of ''Paraburnetia sneeubergensis'' comes from ''para'', meaning beside or near; '' Burnetia'' indicating the first named member of the clade; and ''sneeubergensis'' for the location the Sneeuberge mountains above where the specimen was found. ''P. sneeubergensis'' is known by its knobby skull, which is a shared synapomorphy with ''B. mirabilis'' and ''P. viatkensis'' They are synapsids, from which, their clade of therapsids is derived from.Rubidge, B., & Sidor, C. (2001). Evolutionary patterns among Permo-Triassic therapsids. Annual Review of Ecology and Systematics, 32, 449.

Burnetia
''Burnetia'' is an extinct genus of biarmosuchian therapsids in the family Burnetiidae, from the Late Permian of South Africa. ''Burnetia'' is known so far from a single holotype skull lacking the lower jaws described by South African paleontologist Robert Broom Robert Broom FRS FRSE (30 November 1866 6 April 1951) was a British- South African doctor and palaeontologist. He qualified as a medical practitioner in 1895 and received his DSc in 1905 from the University of Glasgow. From 1903 to 1910, he ... in 1923. Due to erosion and dorsoventral crushing, features of the skull are hard to interpret. Stutural lines are further distorted by the unusual shape of the skull roof, including many bosses and protuberances. Description When broadly looking at the skull, there are well developed “cheeks”, bosses, and pits that resemble Pareiasaurians. However, the small temporal fossa distinguishes it from the Cotylosaur. The overall shape resembles a triangle. In the nasals, t ...

Biarmosuchian
Biarmosuchians are an extinct clade of non-mammalian synapsids from the Permian. They are the most basal group of the therapsids. All of them were moderately-sized, lightly-built carnivores, intermediate in form between basal sphenacodont "pelycosaurs" and more advanced therapsids. Biarmosuchians were rare components of Permian ecosystems, and the majority of species belong to the clade Burnetiamorpha, which are characterized by elaborate cranial ornamentation. Characteristics The biarmosuchian skull is very similar to the sphenacodontid skull, differing only in the larger temporal fenestra (although these are still small relative to later therapsids), slightly backward-sloping occiput (the reverse of the pelycosaur condition), reduced number of teeth, and single large canine teeth in both upper and lower jaws, and other features (Carroll 1988 pp. 370, Benton 2000 p. 114). In later specialised Biarmosuchia, these resemble the enlarged canines of the Gorgonopsia. The pre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lende
''Lende'' is an extinct genus of biarmosuchian from Malawi. It contains one species, ''Lende chiweta'', first described by Jacobs and colleagues in 2005 and is a burnetiamorph – a group of biarmosuchians characterized by numerous bosses and swellings on the skull. The type specimen was discovered in the early 1990s in the Permian Lower Bone Bed (B1) of the Chiweta Beds of Malawi, which are believed to correlate with the ''Cistecephalus'' Assemblage Zone of the South African Karoo Supergroup, the Usili Formation of Tanzania, and the Upper Madumabisa Mudstone of Zambia. The holotype of the genus ''Lende'' is MAL 290, which comprises an almost complete skull The skull is a bone protective cavity for the brain. The skull is composed of four types of bone i.e., cranial bones, facial bones, ear ossicles and hyoid bone. However two parts are more prominent: the cranium and the mandible. In humans, the ... and lower jaw. References {{Taxonbar, from=Q23842813, from2=Q222 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lemurosaurus
''Lemurosaurus'' is a genus of extinct biarmosuchian therapsids from the Late Permian of South Africa. The generic epithet ''Lemursaurus'' is a mix of Latin, lemures “ghosts, spirits”, and Greek, sauros, “lizard”. ''Lemurosaurus'' is easily identifiable by its prominent eye crests, and large eyes. The name ''Lemurosaurus pricei'' was coined by paleontologist Robert Broom in 1949, based on a single small crushed skull, measured at approximately 86 millimeters in length, found on the Dorsfontein farm in Graaff-Reinet.Broom R. New Fossil Reptile Genera from the Bernard Price Collectionhttp://bionames.org/references/842bad4f2b347a534d3e14434670a86b To date, only two skulls of the ''Lemurosaurus'' have been discovered, so body size is unknown. The second larger, more intact, skull was found in 1974 by a team from the National Museum, Bloemfontein. History of discovery The holotype skull was poorly preserved and referred to as BP/1/816.
