The oldest unequivocal records of Dinosauria were unearthed from Late Triassic rocks
(approximately 230 Ma) accumulated over extensional rift basins in southwestern Pangea …

Dinosaurs were remarkably successful during the Mesozoic and one subgroup, birds,
remain an important component of modern ecosystems. Although the extinction of non-avian …

Background The axial skeleton of extinct saurischian dinosaurs (ie, theropods,
sauropodomorphs), like living birds, was pneumatized by epithelial outpocketings of the …

Abstract The Early Jurassic Jenkyns Event (∼ 183 Ma) was characterized in terrestrial
environments by global warming, perturbation of the carbon cycle, enhanced weathering …

The complete osteology of the basal sauropod Tazoudasaurus naimi from the late Early
Jurassic Toundoute continental series of Ouarzazate Province, Morocco, is presented. The …

Summary The importance of adaptation [1–4] versus organizational constraints [5–7] in
shaping common macroevolutionary trends remains unclear [8]. The fossil record is key to …

Many hypotheses have been proposed for the rise of dinosaurs, but their early diversification
remains poorly understood. This paper examines the occurrences, species diversity and …

We present a comprehensive description and phylogenetic analysis of the important
transitional sauropodomorph Antetonitrus ingenipes. New information sheds light on the …

Late Jurassic sauropod trackways from the Jura Mountains (NW Switzerland) and the central
High Atlas Mountains (Morocco) are described and compared. Emphasis is put on track …

Background Sauropod dinosaurs were the largest animals ever to walk on land, and, as a
result, the evolution of their remarkable adaptations has been of great interest. The …
