The Karoo Basin of South Africa has the best global record of Lopingian (Late Permian) non-mammaliaform cynodonts, currently represented by five species. We describe Vetusodon elikhulu gen. et sp. nov., documented by four specimens from the Daptocephalus Assemblage Zone. With a basal skull length of ~18 cm, it is the largest Lopingian cynodont and is also larger than Induan representatives of the group. Vetusodon elikhulu has a cranial morphology that departs notably from that previously… 
A Basal Nonmammaliaform Cynodont from the Permian of Zambia and the Origins of Mammalian Endocranial and Postcranial Anatomy
The occurrence of Nshimbodon indicates that charassognathids, like the basal cynodont Procynosuchus, were geographically widespread in southern Pangea by Lopingian times and provides evidence of correlated transformations in the feeding system, neck, and shoulder, which are consistent with novel mammal-like locomotor and feeding mechanics in the earliest Cynodonts.
Cranial anatomy of Bolotridon frerensis, an enigmatic cynodont from the Middle Triassic of South Africa, and its phylogenetic significance
A computed tomographic reconstruction of BSPG 1934-VIII-7 represents by far the most extensive specimen of B. frerensis, providing novel information on its palatal and internal anatomy and recovering Bolotridon as the sister-taxon of Eucynodontia.
Biostratigraphy of the Daptocephalus Assemblage Zone (Beaufort Group, Karoo Supergroup), South Africa
The name Daptocephalus Assemblage Zone (DaAZ) is re-instated for vertebrate assemblages of the uppermost Permian strata (Balfour, upper Teekloof, and Normandien formations) of South Africa’s main
Spatiotemporal variation in completeness of the early cynodont fossil record and its implications for mammalian evolutionary history
Mammals are the only surviving group of Cynodontia, a synapsid clade that first appeared in the fossil record in the late Permian, ~260 million years ago. Using three metrics that capture skeletal
A re-assessment of the oldest therapsid Raranimus confirms its status as a basal member of the clade and fills Olson's gap.
CT scanning techniques are used to digitally reconstruct the bones and trigeminal canals of the snout of Raranimus in 3D and confirm that RarAnimus shares a high number of synapomorphies with more derived therapsids and is the only theraapsid known so far to display a "pelycosaur"-like maxillary canal bearing a long caudal alveolar canal that gives off branches at regular intervals.
The stapes of Thrinaxodon Seeley, 1894 and Galesaurus Owen, 1859: a case of study for intraspecific variability in basal cynodonts
Stapedial anatomy of Thrinaxodon liorhinus Seeley, 1894 and Galesaurus planiceps Owen, 1859 is surveyed, offering a counterintuitive result of inordinate high intraspecific morphological variation of the stapes of basal non-mammaliaform cynodonts.
Tooth Replacement in the Non-Mammalian Cynodont Cynosaurus suppostus (Therapsida) from the Late Permian of South Africa
Cessation of replacement in the first maxillary postcanine locus is synchronized with the eruption of the replacement tooth in the third locus, which provides possible evidence for a finite number of replacement generations occurring at the active PC1.
Tooth replacement patterns in the Early Triassic epicynodont Galesaurus planiceps (Therapsida, Cynodontia).
The growth series shows that the incisors and postcanines continue to develop and replace, even in the largest (presumably oldest) specimen of the Early Triassic cynodont Galesaurus planiceps, which had a finite number of canine replacement cycles.


A new cynodont record from the Tropidostoma Assemblage Zone of the Beaufort Group: implications for the early evolution of cynodonts in South Africa
A new specimen of cynodont has been recovered from the lower Upper Permian levels of the Tropidostoma Assemblage Zone of the South African Karoo Basin. A series of characters, including the presence
A new taxon of cynodont from the Tropidostoma Assemblage Zone (upper Permian) of South Africa, and the early evolution of Cynodontia
Despite their small size, the holotypes of Abdalodon and Charassognathus probably represent adults and indicate that early evolution of cynodonts may have occurred at small body size, explaining the poor Permian fossil record of the group.
The oldest cynodont: new clues on the origin and early diversification of the Cynodontia
One most parsimonious tree, from an analysis using implied weights, positions Charassognathus as the most basal cynodont, which implies that the Cynodontia initially diversified in Permian Gondwana, in what is now southern Africa.
A new species of the traversodontid cynodont Exaeretodon from the Santa Maria Formation (Middle/Late Triassic) of southern Brazil
The presence of prootic crests in the extensive lateral flange, anterior to the fenestra ovalis, is a noteworthy basicranial trait, unique to this new taxon among non-mammalian cynodonts.
The First Karenitid (Therapsida, Therocephalia) from the Upper Permian of Gondwana and the Biogeography of Permo-Triassic Therocephalians
ABSTRACT Therocephalians were an ecologically diverse group of therapsids whose long stratigraphic record and widespread distribution during Permian and Triassic times make them important for
A new galesaurid (Therapsida: Cynodontia) from the Lower Triassic of South Africa
A new galesaurid cynodont, Progalesaurus lootsbergensis gen. et sp. nov., is described on the basis of a well‐preserved skull, lower jaw, right scapula and left atlantal neural arch. Autapomorphies
A new record of Procynosuchus delaharpeae (Therapsida: Cynodontia) from the Upper Permian Usili Formation, Tanzania
Procynosuchus, the best-known Permian cynodont, has a remarkably broad geographic range, with records stretching from southern Africa to Europe. Fossils of Procynosuchus are most common in the Upper
A procynosuchid cynodont from central Europe
Diversified assemblages of non-mammalian synapsids (or mammal-like reptiles) have long been known from the Upper Permian of southern Africa1 and the Russian Platform2. In contrast, Upper Permian
New Material of Microgomphodon oligocynus (Eutherapsida, Therocephalia) and the Taxonomy of Southern African Bauriidae
An exceptionally well-preserved specimen of the bauriid therocephalian Microgomphodon oligocynus from the Burgersdorp Formation (Early-Middle Triassic, Cynognathus Assemblage Zone) of the South
A cladistic analysis of 32 taxa (two gorgonopsians, seven therocephalians and 23 cynodonts) and 96 craniodental characters places P. elegans as sister taxon of Eucynodontia, and indicates paraphyly for Therocephalia, with the whaitsiid Theriognathus identified as sisterTaxon of CynodontIA.
