The conclusion reached in this paper is that the cynodonts evolved from a therocephalian ancestor, and that among the known therocephalians, the whaitsiids are the forms closest to cynodont ancestry. Certain superficial specializations of the feeding apparatus, however, debar the known whaitsiids from a position of actual cynodont ancestry. The evidence for this thesis lies in new detailed morphology of certain points of the whaitsiid skull, along with reassessment of much of the established… 
On the homology of the alisphenoid
Mammalian skulls differ from those of recent reptiles in having a temporal fossa with part of its wall formed by an expanded alisphenoid. Much new information has been obtained about the cranium in
Revision of the first therocephalian, Theriognathus Owen (Therapsida: Whaitsiidae), and implications for cranial ontogeny and allometry in nonmammaliaform eutheriodonts
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).
Reassessment of the Morphology and Paleobiology of the Therocephalian Tetracynodon Darti (Therapsida), And The Phylogenetic Relationships of Baurioidea
The brain is strikingly plesiomorphic in many features, but generally shows features that are intermediate between gorgonopsians and cynodonts, thus clarifying this stage of the evolution of the synapsid brain.
Adult morphology of the therocephalian Simorhinella baini from the middle Permian of South Africa and the taxonomy, paleobiogeography, and temporal distribution of the Lycosuchidae
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.
The skeleton of a baurioid therocephalian therapsid from the Lower Triassic (Lystrosaurus Zone) of South Africa
The first full reconstruction of a baurioid (“scaloposaur”) therocephalian is given, showing that these therapsids were very mammal-like in their proportions, with relatively long limbs, attenuated lumbar ribs, and a highly reduced tail.
The Endocranial Cavity of a Nonmammalian Eucynodont, Chiniquodon theotenicus, and Its Implications for the Origin of the Mammalian Brain
ABSTRACT The braincase and endocranial cavity of a specimen of a nonmammalian eucynodont Chiniquodon is described and illustrated, and a tentative reconstruction of the gross anatomy of the brain
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.
The Primitive Cynodont Procynosuchus: Functional Anatomy of the Skull and Relationships
The anatomy of the internal nares indicates that an arrangement of Jacobson’s organ and associated nerves, blood vessels and glands comparable to that of monotremes was present and an attempt is made to interpret its anatomy in functional terms.
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.
New whaitsioids (Therapsida: Therocephalia) from the Teekloof Formation of South Africa and therocephalian diversity during the end-Guadalupian extinction
The oldest Gondwanan whaitsiid Microwhaitsia and additional records from the lower strata of the Teekloof Formation suggest thatWhaitsioids had diversified by the early Wuchiapingian and no later than Pristerognathus Assemblage Zone times, which imply increasing faunal turnover from Guadalupian to Lopingian (late Permian) times.


New Late Permian Therocephalian
The well-preserved, acid-prepared skull of Moschowhaitsia vjuschkovi reveals a number of features unexpected in a theriodont of otherwise generally primitive aspect.
Morphology and systematics of the northern Dvina Cynodonts lReptiliac Therapsidas upper Permianr
The morphological peculiarities of this Northern Dvina cynodont justify its being set apart in a separate family Dviniidae related to the Procynosuchidae — the extremely primitive Cynodonts of South Africa.
Researches on the Structure, Organization, and Classification of the Fossil Reptilia. VI. On the Anomodont Reptilia and Their Allies
The chief contributions to a knowledge of the Anomodont skull have been made by Sir Richard Owen, Professor Huxley, and Professor Cope, who said to show a blending of Chelonian and Lizard structures.
On the Functional Morphology of the Gorgonopsid Skull
It is proposed that the carnivorous therapsids should be classified into two equal ranks, the Gorgonopsia and the Theriodonta and that they were probably derived separately from the sphenacodont pelycosaurs.

This paper uses a functional interpretation of the postcranial anatomy of certain advanced mammal-like reptiles and the phylogenetic implications of monotreme biology to evaluate the question of the kind of biological organization that characterized the transitional forms on or near the reptilemammal boundary.
The interrelations of early mammals
If a mammal is defined as a synapsid with a squamosal—dentary jaw articulation, the Class Mammalia includes six quite discrete groups; the animals comprising each group are clearly related to each other, while their relationship to the members of any of the other groups is quite uncertain.
On the Upper Triassic Mammals
It is claimed that the view that the eozostrodonts are triconodonts and represent the basic mammalian stock from which later triconODonts, the trituberculates, the docodontS and possibly the multituberculate evolved, is well founded.
On the Structure of the Skull in the Mammal-Like Reptiles of the Suborder Therocephalia
The first-known mammal-like reptiles were discovered by Andrew Geddes Bain (1845) in the Karroo Beds of South Africa about a hundred years ago. The large majority of the species he discovered belong
On the scaloposaurid skull of Olivieria parringtoni, Brink with a note on the origin of hair
The writer undertook an examination of the type specimen of Olivieria because it seemed well suited to a study of the sensory nerve supply of the muzzle, and found it to represent the preliminary ecological niche required for ground-living reptiles to emerge in due course as mammals.
On the evolution of the mammalian palate
The current parasphenoidvomer hypothesis is founded mostly on embryology, while the doubts of its validity have arisen from a consideration of recent palaeontological evidence, and the importance of the problem lies in the necessity of finding an explanation which satisfies both lines of evidence.
