The phylogeny of the ‘higher’ temnospondyls (Vertebrata: Choanata) and its implications for the monophyly and origins of the Stereospondyli
TLDR
It is suggested that the radiation of the diverse stereospondyl clades, the Capitosauria and Trematosauria, began in the Late Permian of Gondwana, in a «safe haven» that was less severely affected by the LatePermian extinction event.
A new species of the primitive dinosaur Thecodontosaurus (Saurischia: Sauropodomorpha) and its implications for the systematics of early dinosaurs

Synopsis Juvenile sauropodomorph specimens from a Late Triassic/Early Jurassic fissure fill in Pant‐y‐ffynnon Quarry, South Wales are redescribed and named as a new species, Thecodontosaurus caducus.
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.
The species taxonomy of the sauropodomorph dinosaurs from the Löwenstein Formation (Norian, Late Triassic) of Germany

  • Environmental Science
  • 1 March 2003
TLDR
It was found that two discrete taxa comprise the current hypodigm of Sellosaurus, the more common form of which is a plesiomorphic form for which the correct name is Efraasia minor comb and is placed in this genus as Plateosaurus gracilis.

TLDR
A partial dinosaur skeleton from the Upper Triassic (Norian) sediments of South Africa is described and named Antetonitrus ingenipes, which is the oldest known definitive sauropod.
Solving a dinosaurian puzzle: the identity of Aliwalia rex Galton

  • 1 January 2007
TLDR
Eucnemesaurus fortis Van Hoepen 1920 from the Late Triassic of South Africa is demonstrated to be the senior synonym of the puzzling dinosaur taxon Aliwalia rex Galton 1985 and it supports the paraphyletic nature of the traditional ‘prosauropod’ assemblage.
A new theropod dinosaur from the Early Jurassic of South Africa and its implications for the early evolution of theropods
TLDR
It is now the majority view amongst theropod systematists that Ceratosauria contains Ceratosaurus spp.
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.
The complete anatomy and phylogenetic relationships of Antetonitrus ingenipes (Sauropodiformes, Dinosauria): implications for the origins of Sauropoda
