Palaeosaurus (?) diagnosticusHuene from the Stubensandstone (Upper Triassic, Norian) of Nordwürttemberg, Germany is made the type species of a new genus of prosauropod dinosaurEfraasia, which is referred to the family Anchisauridae. The anatomy ofEfraasia diagnostica is conservative and it was an ideal ancestor for the later and more specializedAnchisaurus polyzelus of North America. The slenderness of the manus and pes ofEfraasia andAnchisaurus is matched amongst prosauropods only by the feet… 

The anatomy and phylogenetic position of the Triassic dinosaur Staurikosaurus pricei Colbert, 1970

The phylogenetic position of S. pricei is constrained by that of its sister taxon H. ischigualastensis, which is known from much more complete material, and the absence of some characters observed in the clades Theropoda and Sauropodomorpha suggests that S.pricei is not a member of Eusaurischia.

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.

ANATOMY AND SYSTEMATICS OF THE PROSAUROPOD DINOSAUR THECODONTOSAURUS ANTIQUUS FROM THE UPPER TRIASSIC OF SOUTHWEST ENGLAND

Abstract Re-examination of the surviving specimens of Thecodontosaurus antiquus indicates that this plesiomorphic sauropodomorph can be diagnosed on the basis of elongate basipterygoid processes, a

OnStaurikosaums pricei, an early saurischian dinosaur from the Triassic of Brazil, with notes on the Herrerasauridae and Poposauridae

The anatomy of the saurischian dinosaurStaurikosaums pricei Colbert from the Santa Maria Formation (Middle or Upper Triassic) of Rio do Sul, Brazil is redescribed.Staurikosaurus has 9 (or possibly

Anatomy of a basal sauropodomorph dinosaur from the Early Jurassic Hanson Formation of Antarctica

The anatomy of a basal sauropodomorph (Dinosauria: Saurischia) from the Early Jurassic Hanson Formation of Antarctica is described in detail and preliminary phylogenetic analyses suggest a close relationship between the new Antarctic taxon and Lufengosaurus.

New information on the systematics and postcranial skeleton of Herrerasaurus ischigualastensis (Ther

New evidence supports this group as saurischian dinosaurs: the posterior process of the jugal is forked, a hyposphene-hypantrum articulation is present in dorsal vertebrae, the distal shaft of the ischium is rod-like, and six other saurishian synapomorphies are present.

Redescription of a Nearly Complete Skull of Plateosaurus (Dinosauria: Sauropodomorpha) from the Late Triassic of Trossingen (Germany)

This study supports referral of AMNH FARB 6810 to P. erlenbergiensis on the basis of the following characters: occipital condyle above level of parasphenoid; basisphenoid with transverse, subvertical lamina extending between basipterygoid processes; and peglike process projecting medially from the middle of the palatine.

New material and revision of Melanorosaurus thabanensis, a basal sauropodomorph from the Upper Triassic of Lesotho

The holotype femur of Melanorosaurus thabanensis is redescribed from the Elliot Formation of Lesotho, as well as associated remains, and the first phylogenetic analysis including both this specimen and Melanosaurus is conducted, leading to the conclusion that the femur described in the original publication can no longer be referred to Melanoriansaurus.

A Basal Sauropodomorph (Dinosauria: Saurischia) from the Ischigualasto Formation (Triassic, Carnian) and the Early Evolution of Sauropodomorpha

The presence of Panphagia at the base of the early Carnian Ischigualasto Formation suggests an earlier origin of Sauropodomorpha during the Middle Triassic, and is regarded as the most basal sauropodomorph.

The cotylosaurs included the ancestors of the sauropsids and the theropsids—the captorhinomorphs belonging to the latter group, and the position of the millerosaurs is critical, and in the interests of neutrality they are included in the documentation as submitted.

On the origin of the sauropods and the classification of the Saurischia

Re-examination of melanorosaurid material in South Africa shows that none is properly associated and that the proportions cannot be determined, and concepts of sauropodomorph phylogeny are incompatible with the stratigraphical position of the Melanorosauridae below the Thecodontosauridae (in South Africa).

The cheeks of ornithischian dinosaurs

The evolution of self-sharpening cheek teeth and of cheeks enabled ornithischians to eat much more resistant plant material and resulted in ornithishians replacing prosauropods as the ‘small to medium sized’ terrestrial herbivores (up to 10 m).

Classification and Evolution of Ornithopod Dinosaurs

The premaxillary teeth as a diagnostic feature, cheeks, cheek teeth and locomotor capabilities, and the current classification of the family Hypsilophodontidae are disagreed with.
