The evolution of sauropod feeding mechanisms
Introduction Sauropods were gigantic, long-necked, herbivorous dinosaurs, which dominated many Jurassic and Cretaceous terrestrial faunas. First appearing in the fossil record during the EarlyExpand

A phylogenetic analysis of basal sauropodomorph relationships: Implications for the origin of sauropod dinosaurs2
New discoveries, revision of existing taxa and the application of cladistic analysis have all shed light on the relationships of basal sauropodomorphs. Nevertheless, the interrelationships proposedExpand

A new hypothesis of dinosaur relationships and early dinosaur evolution
For 130 years, dinosaurs have been divided into two distinct clades—Ornithischia and Saurischia. Here we present a hypothesis for the phylogenetic relationships of the major dinosaurian groups thatExpand

Homeotic effects, somitogenesis and the evolution of vertebral numbers in recent and fossil amniotes
The development of distinct regions in the amniote vertebral column results from somite formation and Hox gene expression, with the adult morphology displaying remarkable variation among lineages.Expand

Estimating the effects of sampling biases on pterosaur diversity patterns: implications for hypotheses of bird/pterosaur competitive replacement
Abstract Pterosaurs were the first flying vertebrates and formed important components of terrestrial and marginal marine ecosystems during the Mesozoic. They became extinct during the latestExpand
