The largest known dinosaurs weighed at least 20 million times as much as the smallest,
indicating exceptional phenotypic divergence. Previous studies have focused on extreme …

Inferring the body mass of fossil taxa, such as non‐avian dinosaurs, provides a powerful tool
for interpreting physiological and ecological properties, as well as the ability to study these …

Animal performance fundamentally influences behaviour, ecology, and evolution. It typically
varies monotonously with size. A notable exception is maximum running speed; the fastest …

Abstract The Late Jurassic Tendaguru Formation of Tanzania, southeastern Africa, records a
rich sauropod fauna, including the diplodocoids Dicraeosaurus and Tornieria, and the …

The first fossil remains of vertebrates, invertebrates, plants and palynomorphs of the
Chorrillo Formation (Austral Basin), about 30km to the SW of the town of El Calafate …

Dinosaurs dominated Mesozoic terrestrial ecosystems globally. However, whereas a pole-to-
pole geographic distribution characterized ornithischians and theropods, sauropods were …

Dinosaurs dominated the terrestrial ecosystems for more than 140 Myr during the Mesozoic
era, and among them were sauropodomorphs, the largest land animals recorded in the …

Early members of the dinosaur–pterosaur clade Ornithodira are very rare in the fossil record,
obscuring our understanding of the origins of this important group. Here, we describe an …

The titanosaurian sauropod dinosaur Mendozasaurus neguyelap is represented by several
partial skeletons from a single locality within the Coniacian (lower Upper Cretaceous) Sierra …

In the last two decades, the number of phylogenetically informative anatomical characters
recognized in the appendicular skeleton of titanosaurian sauropod dinosaurs has increased …
