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.Expand

A new transitional sauropodomorph dinosaur from the Early Jurassic of South Africa and the evolution of sauropod feeding and quadrupedalism
Aardonyx celestae gen. et sp. nov. is described from the upper Elliot Formation (Early Jurassic) of South Africa. It can be diagnosed by autapomorphies of the skull, particularly the jaws, cervicalExpand

The earliest known sauropod dinosaur and the first steps towards sauropod locomotion
A partial dinosaur skeleton from the Upper Triassic (Norian) sediments of South Africa is described and named Antetonitrus ingenipes. It provides the first informative look at a basal sauropod thatExpand

The species taxonomy of the sauropodomorph dinosaurs from the Löwenstein Formation (Norian, Late Triassic) of Germany
The species taxonomy of the sauropodomorph dinosaurs from the Lowenstein Formation of Germany is examined. Previous work has classified these into two taxa: Sellosaurus gracilis from a number ofExpand

A new theropod dinosaur from the Early Jurassic of South Africa and its implications for the early evolution of theropods
INTRODUCTION Prior to Gauthier’s classic (1986) monograph, our understanding of the interrelationships of theropod dinosaurs could be described as murky at best. Most works still adhered to the oldExpand

The Triassic Amphibian Thoosuchus yakovlevi and the Relationships of the Trematosauroidea (Temnospondyli: Stereospondyli)
A skull of the basal trematosauroid temnospondyl Thoosuchus yakovlevi from the Early Triassic of Russia is described. Characters showing phylogenetic affinities with the Trematosauroidea include theExpand

A definite prosauropod dinosaur from the Lower Elliot Formation (Norian: Upper Triassic) of South Africa
A new sauropodomorph dinosaur specimen is described and identified as a prosauropod. It is tentatively placed as the sister taxon of Riojasaurus incertus from Argentina. The systematic position ofExpand

The Early Evolution of Postcranial Skeletal Pneumaticity in Sauropodomorph Dinosaurs
Postcranial skeletal pneumaticity (PSP) is present in a range of basal sauropodomorphs spanning the basal sauropodomorph—sauropod transition. We describe the PSP of five taxa, PlateosaurusExpand

A new basal sauropod from the pre-Toarcian Jurassic of South Africa: evidence of niche-partitioning at the sauropodomorph–sauropod boundary?
The early evolution of sauropod dinosaurs remains poorly understood, with a paucity of unequivocal sauropod taxa known from the first twenty million years of the Jurassic. Recently, the EarlyExpand

Abstract:  Dicynodont therapsids were near-ubiquitous components of Permo-Triassic terrestrial faunas, but the morphology of many of the nominal species remains poorly understood. Here we provide aExpand
