Biology of the sauropod dinosaurs: the evolution of gigantism
The herbivorous sauropod dinosaurs of the Jurassic and Cretaceous periods were the largest terrestrial animals ever, surpassing the largest herbivorous mammals by an order of magnitude in body mass.Expand
Osteology and phylogenetic relationships of Tehuelchesaurus benitezii (Dinosauria, Sauropoda) from the Upper Jurassic of Patagonia
The diversification and early evolution of neosauropod dinosaurs is mainly recorded from the Upper Jurassic of North America, Europe, and Africa. Our understanding of this evolutionary stage is farExpand
A tyrannosauroid dinosaur from the Upper Jurassic of Portugal
Fragmentary theropod remains from the Upper Jurassic (Kimmeridgian) of Guimarota, Portugal, represent a new taxon of theropod dinosaurs, Aviatyrannis jurassica gen. et sp. nov. Together withExpand
Dinosaur teeth from the Barremian of Uña, Province of Cuenca, Spain
Abstract The dinosaur fauna from the Barremian locality of Una, east-central Spain, is described on the basis of isolated teeth. Apart from an unidentified sauropod and a probably new basalExpand
Was Dinosaurian Physiology Inherited by Birds? Reconciling Slow Growth in Archaeopteryx
Background Archaeopteryx is the oldest and most primitive known bird (Avialae). It is believed that the growth and energetic physiology of basalmost birds such as Archaeopteryx were inherited inExpand
New specimen of Archaeopteryx provides insights into the evolution of pennaceous feathers
Discoveries of bird-like theropod dinosaurs and basal avialans in recent decades have helped to put the iconic ‘Urvogel’ Archaeopteryx into context and have yielded important new data on the originExpand
A Jurassic mammal from South America
The Jurassic period is an important stage in early mammalian evolution, as it saw the first diversification of this group, leading to the stem lineages of monotremes and modern therian mammals.Expand
First record of the family Dromaeosauridae (Dinosauria: Theropoda) in the Cretaceous of Gondwana (Wadi Milk Formation, northern Sudan)
KurzfassungDie cenomane Wadi Milk Formation des Sudan lieferte eine reiche kontinentale Wirbeltierfauna. Neben Fragmenten von großen Theropoden verweisen disartikulierte Fußphalangen-Elemente und einExpand
