 Digimorph - Diademodon sp. (Cynodont)
Diademodon is a distant extinct relative of mammals that lies along the Cynodontia lineage.
Members of Cynodontia, including mammals, are known as cynodonts.
Fossils of Diademodon are found mainly in the Lower Triassic Cynognathus zone of the Karroo Basin of South Africa.

 Palaeos Vertebrates 410.300 Cynodontia: Probainognathia
Although previously separated from other theriodonts as a distinct infraorder, the Ictidosauria, study of the type and only specimen of the genus the Trithelodon has determined its close affinities with the typical Ictidosaurs Pachygenelus and "Diarthrognathus".
For this reason, Hopson and Kitching (1972) suggested using the family name Trithelodontidae Broom 1912 for all of the forms called "ictidosaurs", and included all these groups under the Cynodontia.
The Trithelodonts (Ictidosaurs) are thus very advanced, probably insectivorous, cynodonts of small size in which some incisors and in some species the upper and probably postcanines have a transversely-oriented cutting edge, in others the uppers have an oblique and the lowers a longitudinal cutting edge.

 The Cynodontia
The non-mammalian therapsids are divided into five major clades, namely the Dinocephalia, Gorgonopsia, Anomodontia, Therocephalia and the Cynodontia (Kemp, 1982; Hopson, 1994; Rubidge and Sidor, 2001).
The only non-mammalian therapsid clade to survive the Triassic period was the Cynodontia (sensu Rubidge and Sidor, 2001).
The members of this group acquired increasingly more derived mammalian features, such as an enlarged dentary, reduced reflected lamina, bony secondary palate, complex postcanine dentition, reduced lumbar ribs and parasagittal gait, with the first true mammals appearing by the end of the Triassic (Cluver, 1978; Benton, 1990; Pough, et al., 1996).

Cynodontia is the particular suborder of the order Therapsida from which evolutionists believe mammals evolved.
They are the only therapsids to “show a significant approach to the mammalian condition in their general morphology” (Carroll, p.
Several genera of the family Galesauridae (infraorder Procynosuchia, suborder Cynodontia) are among the cynodonts appearing in the Upper Permian (Carroll, p.

 Digimorph - Thrinaxodon liorhinus (fossil cynodont)
Only about two dozen reasonably complete and well-preserved specimens are known, most of which were discovered in South Africa and reside in museums in Cape Town, Bloemfontein, and Johannesburg.
Thrinaxodon is a basal member of Cynodontia, a lineage that includes mammals and their closest extinct relatives.
Thrinaxodon preserves a combination of primitive and derived characters, showing an early stage in the evolution of the characteristics that distinguish modern mammals from other living species.

One advanced group of Therapsids, called the Cynodontia, had evolved several other distinctly mammalian characteristics: mammalian like teeth, with several cusps.
Cynodonts also evolved a much more mammalian kind of skeleton, with very slender limbs held much closer to the body, which made for more agile locomotion.
The suborder Cynodontia gave rise to the class Mammalia.

 - Reappraising the ''Crown Jewel'' -
They are the only therapsids to “show a significant approach to the mammalian condition in their general morphology.” (Carroll, 378.) There is, however, no fossil record of the ancestry of the cynodonts.
However, in no case is such a long history known by even a single specimen, and therefore it is much more reasonable to accept that very high rates of morphological evolution characteristically occur following a mass extinction [Emphasis added].
Several genera of the family Galesauridae (infraorder Procynosuchia, suborder Cynodontia) are among the cynodonts appearing in the Upper Permian.
