A new transitional sauropodomorph dinosaur from the Early Jurassic of South Africa and the evolution of sauropod feeding and quadrupedalism
TLDR
Cursorial ability appears to have been reduced and the weight bearing axis of the pes shifted to a medial, entaxonic position, falsifying the hypothesis that entaxony evolved in sauropods only after an obligate quadrupedal gait had been adopted.
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.
A new trirachodontid cynodont from the lower levels of the Burgersdorp Formation (Lower Triassic) of the Beaufort Group, South Africa and the cladistic relationships of Gondwanan gomphodonts
TLDR
A new trirachodontid cynodont is described from the base of the Burgersdorp Formation (Subzone A fauna of the Cynognathus Assemblage Zone), of the South African Karoo Basin and is characterized by circular to ovoid in outline upper postcanines and the absence of a maxillary platform lateral to the postcanine series.
A new basal sauropod from the pre-Toarcian Jurassic of South Africa: evidence of niche-partitioning at the sauropodomorph–sauropod boundary?
TLDR
Key changes in the dentition, axial skeleton and forelimb of this new species suggest a genuine functional distinction occurring at the sauropodiform-sauropod boundary, which may partially explain the rarity of true sauropods in the basal rocks of the Jurassic.
CYNODONTS FROM THE UPPERMOST BURGERSDORP FORMATION, SOUTH AFRICA, AND THEIR BEARING ON THE BIOSTRATIGRAPHY AND CORRELATION OF THE TRIASSIC CYNOGNATHUS ASSEMBLAGE ZONE
Abstract The Burgersdorp Formation in the Beaufort Group of the South African Karoo Basin records a diverse and rich vertebrate fauna that is referred biostratigraphically to the Cynognathus
Is the vertebrate-defined Permian-Triassic boundary in the Karoo Basin, South Africa, the terrestrial expression of the end-Permian marine event?
The end-Permian extinction records the greatest ecological catastrophe in Earth history. The vertebrate fossil record in the Karoo Basin, South Africa, has been used for more than a century as the
A Cosmogenic view of erosion, relief generation, and the age of faulting in southern Africa
Southernmost Africa, with extensive upland geomorphic surfaces, deep canyons, and numerous faults, has long interested geoscientists. A paucity of dates and low rates of background seismicity make it
First trematosaurid temnospondyl from the Lystrosaurus Assemblage Zone of South Africa and its biostratigraphic implications
A large temnospondyl mandible from the Lystrosaurus Assemblage Zone (Early Triassic) of South Africa is referred to the higher-level taxon Trematosauridae. The mandible is remarkably similar to that
