The postcranial skeletal anatomy of the therocephalian Regisaurus (Therapsida: Regisauridae) and its utilization for biostratigraphic correlation [PDF]
The postcranial morphology of the therocephalian genus Regisaurus from the Lystrosaurus Assemblage Zone of South Africa is described. The remarkably complete state of preservation of the vertebral column has, for the first time, provided a full ...

A RE-EVALUATION OF THE SYSTEMATICS AND MORPHOLOGY OF CERTAIN ANOMODONT THERAPSIDA [PDF]
The cranial morphology of a number of specimens assigned to the genera Oudenodon, Rhachiocephalus, Aulacephalodon and Pelanomodon was investigated (Keyser, 1969). It was found that the internal morphology and the general structure of the skulls show

The palatal dentition of tetrapods and its functional significance [PDF]
The presence of a palatal dentition is generally considered to be the primitive condition in amniotes, with each major lineage showing a tendency toward reduction. This study highlights the variation in palatal tooth arrangements and reveals clear trends

The quality of the fossil record of anomodonts (Synapsida, Therapsida)
Abstract The quality of the fossil record of anomodont synapsids, one of the major clades of Permian–Triassic terrestrial tetrapods, is assessed. A Character Completeness Metric (CCM2) is calculated for each taxon and consecutive time intervals at a global scale and in the South African Karoo Basin.

A new specimen of Dicynodon traquairi (Newton) (Synapsida: Anomodontia) from the Late Permian (Tartarian) of northern Scotland [PDF]
A recently discovered natural mould of a complete, almost undistorted, skull and lower jaw of a dicynodont (c. 237mmoverall length), in a block of Upper Permian sandstone (= Dicynodon Assemblage Zone: Hopeman Sandstone Formation) from Clashach Quarry ...

Biology, not environment, drives major patterns in maximum tetrapod body size through time [PDF]
Abiotic and biological factors have been hypothesized as controlling maximum body size of tetrapods and other animals through geological time. We analyse the effects of three abiotic factors—oxygen, temperature and land area—on maximum size of Permian ...

Dentition and feeding niche of Endothiodon (Synapsida; Anomodontia). [PDF]
Main articleThe cranial morphology and extensive dentition of the dicynodont therapsid Endothiodon are different from those of any other dicynodont and it clearly had a different feeding niche.

Lycaenops contains one of the most anatomically complete gorgonopsian specimens (AMNH FARB 2240) known and is thought to represent one of the more taxonomically diverse forms, with several species historically attributed to it.

The end-Permian biotic crisis (~252.5 Ma) represents the most severe extinction event in Earth's history. This paper investigates diversity patterns in Anomodontia, an extinct group of therapsid synapsids ('mammal-like reptiles'), through time and in ...

A REVISED CLASSIFICATION OF CYNODONTS (REPTILIA; THERAPSIDA) [PDF]
Cynodonts are very advanced mammal-like reptiles of the Permian-Triassic which are of special interest to evolutionists because they gave rise to the Class Mammalia during Middle or Late Triassic time.
