An exceptionally well-preserved specimen of the bauriid therocephalian Microgomphodon oligocynus from the Burgersdorp Formation (Early-Middle Triassic, Cynognathus Assemblage Zone) of the South African Karoo is described. In addition, a taxonomic revision of bauriid therocephalians from southern Africa, based on firsthand examination of almost all know specimens, is presented. Microgomphodon oligocynus and Bauria cynops are recognized as the only valid species of southern African bauriids… 
Adult morphology of the therocephalian Simorhinella baini from the middle Permian of South Africa and the taxonomy, paleobiogeography, and temporal distribution of the Lycosuchidae
TLDR
The skull and partial skeleton of a large therocephalian from the uppermost Tapinocephalus Assemblage Zone of South Africa is described and forms the basis for a taxonomic re-evaluation of the Lycosuchidae as well as of the geographic and stratigraphic range of the family.
Revision of the first therocephalian, Theriognathus Owen (Therapsida: Whaitsiidae), and implications for cranial ontogeny and allometry in nonmammaliaform eutheriodonts
TLDR
The results suggest that the single species, Theriognathus microps, represented one of the most abundant Late Permian therocephalians in southern Africa and is consequently a potentially useful biostratigraphic marker for the upper Cistecephalus-lower Dicynodon Assemblage Zone transition (i.e., late Wuchiapingian).
A New Large Gomphodont from the Triassic of South Africa and Its Implications for Gondwanan Biostratigraphy
ABSTRACT A partial skull (BP/1/7976) of a very large cynodont from the Middle Triassic Cynognathus Assemblage Zone (Cricodon-Ufudocyclops subzone) of South Africa is described. The specimen
A Re-Description of ‘Mycterosaurus’ smithae, an Early Permian Eothyridid, and Its Impact on the Phylogeny of Pelycosaurian-Grade Synapsids
TLDR
An expanded version of a recently published phylogenetic analysis of pelycosaurian-grade synapsids positions Vaughnictis as the sister taxon of Eothyris within the clade Eothirididae, and confirms the recently-disputed position of caseasaurs as the most basal synapsid.
New information on the postcranial skeleton of Massetognathus ochagaviae Barberena, 1981 (Eucynodontia, Traversodontidae), from the Middle Triassic of Southern Brazil
Abstract New postcranial remains of Massetognathus ochagaviae are described based on a new specimen collected at the Dinodontosaurus Assemblage Zone from the Middle Triassic of Southern Brazil.
Cranial anatomy of the gorgonopsian Cynariops robustus based on CT-reconstruction
TLDR
Inclusion of Cynariops in a phylogenetic analysis of Gorgonopsia recovers it within a large clade of African taxa, more closely related to Lycaenops and rubidgeines than Eriphostoma or Gorg onops.
Taxonomy of the proterosuchid archosauriforms (Diapsida: Archosauromorpha) from the earliest Triassic of South Africa, and implications for the early archosauriform radiation
TLDR
It is concluded that the holotype of Proterosuchus fergusi is undiagnostic, and a neotype is proposed for the species, suggesting a greater species richness of earliest Triassic archosauriforms than previously appreciated.
A New Eutherocephalian (Therapsida, Therocephalia) from the Upper Permian Madumabisa Mudstone Formation (Luangwa Basin) of Zambia
TLDR
The new therocephalian therapsid Ichibengops munyamadziensis adds to a list of sister-group pairs of Wuchiapingian tetrapods in southern Gondwana and Laurasia, indicating that effective, though largely unknown, dispersal routes persisted in Pangea at least through early late Permian times.
On the Validity and Phylogenetic Position of Eubrachiosaurus browni, a Kannemeyeriiform Dicynodont (Anomodontia) from Triassic North America
TLDR
Inclusion of Eubrachiosaurus in a revised phylogenetic analysis of anomodont therapsids indicates that it is a stahleckeriid closely related to the South American genera Ischigualastia and Jachaleria, which alters perception of Late Triassic dicynodont diversity in the northern hemisphere.
Cranial osteology of Arctognathus curvimola, a short‐snouted gorgonopsian from the Late Permian of South Africa
TLDR
The South African gorgonopsian species Arctognathus curvimola is redescribed based on a well-preserved skull and Autapomorphies identified for A. curvimola include a characteristic curvature to the alveolar margin of the snout, extremely reduced lacrimal, lengthy upper postcanine tooth row and a unique vomerine morphology.

GOMPHODONT CYNODONTS OF THE CHAÑARES FORMATION: THE ANALYSIS OF AN ONTOGENETIC SEQUENCE
TLDR
Consideration of qualitative characters together with the allometric results lead to the conclusion that all forms belong to a single species in a growth series, and Massetognathus pascuali is recognized as the only valid entity.

The cranial anatomy of Kombuisia frerensis Hotton (Synapsida, Dicynodontia) and a new phylogeny of anomodont therapsids
TLDR
The general topology of this phylogeny supports the main aspects of recent hypotheses of anomodont relationships, and not only resolves critical nodes at the base of the Dicynodontia that were previously obscured by polytomies, but also introduces new hypotheses of relationships.
Cranial Anatomy of Ennatosaurus tecton (Synapsida: Caseidae) from the Middle Permian of Russia and the Evolutionary Relationships of Caseidae
TLDR
Phylogenetic analysis of Caseidae yields a single most parsimonious tree and its topology reveals that the pattern of dental complexity in terms of the number of apical cuspules is homoplasious, cautioning against its use as a unidirectional phylogenetic character.

We report on a partial varanopid skull and mandible from the Pristerognathus Assemblage Zone of the Beaufort Group, in the South African Karoo Basin, which is probably latest Middle Permian
Anatomy and Phylogenetic Relationships of Boreogomphodon jeffersoni (Cynodontia: Gomphodontia) from the Upper Triassic of Virginia
TLDR
Phylogenetic analysis suggests the existence of a clade comprising Boreogomphodon plus two other taxa in the Northern Hemisphere that is the sister group to most other known Middle and Late Triassic traversodonts from Gondwana.
