A systematic revision and phylogenetic analysis of Triassic mastodonsauroids (Temnospondyli: Stereospondyli)
TLDR
The Mastodonsauroidea must have a ghost lineage extending back to at least the Late Permian, when the common ancestor of the MastodONsauridae and the Trematosauroid ancestors diverged from rhinesuchid ancestors.
Earliest evidence of cynodont burrowing
TLDR
A 251 million year old partial burrow cast containing an articulated skeleton of the mammal–like carnivore Thrinaxodon liorhinus is the oldest evidence for burrowing by a cynodont synapsid, and indicates that burrow–making was broadly distributed in basal synapsids and has a long history in non–mammalian synapid evolution.
Parotosuchus (Amphibia, Temnospondyli) from the Cynognathus Assemblage Zone (Early Triassic) of South Africa: cranial morphology and relationships
A partial ‘capitosaurid’ amphibian skull from the lowest subzone of the Cynognathus Assemblage Zone of South Africa is referred to Parotosuchus haughtoni, a species previously known only from a
The Triassic Amphibian Thoosuchus yakovlevi and the Relationships of the Trematosauroidea (Temnospondyli: Stereospondyli)
TLDR
A preliminary phylogenetic analysis of trematosauroid relationships confirms that Benthosuchus is a basal treMatosaurian rather than a basal mastodonsauroid, and that ThoosuchUS is the sister group to all other trematOSauroids.
Reassessment of the Morphology and Paleobiology of the Therocephalian Tetracynodon Darti (Therapsida), And The Phylogenetic Relationships of Baurioidea
TLDR
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.
THE VERTEBRATE FAUNA OF THE UPPER PERMIAN OF NIGER. IV. NIGERPETON RICQLESI (TEMNOSPONDYLI: COCHLEOSAURIDAE), AND THE EDOPOID COLONIZATION OF GONDWANA
TLDR
The discovery of Nigerpeton strengthens support for the hypothesis that West Africa hosted an endemic fauna at the close of the Paleozoic Era and proposes that Late Carboniferous and Permian edopoids were geographically widespread and that they twice crossed the Central Pangean mountain chain (between Laurussia and Gondwana) during their evolution.

A NEW BRACHYOPID TEMNOSPONDYL FROM THE CYNOGNATHUS ASSEMBLAGE ZONE, UPPER BEAUFORT GROUP, SOUTH AFRICA
Abstract A new brachyopid temnospondyl is described from the Early to Middle Triassic Cynognathus Assemblage Zone of the upper Beaufort Group, Karoo Basin of South Africa. Vanastega plurimidens, gen.
Permian tetrapods from the Sahara show climate-controlled endemism in Pangaea
TLDR
The results show that long-standing theories of Late Permian faunal homogeneity are probably oversimplified as the result of uneven latitudinal sampling, and suggest that faunas from the poorly sampled xeric belt that straddled the Equator during thePermian period differed markedly from well-sampled fauna that dominated tropical-to-temperate zones to the north and south.
