▪ Abstract Phylogenetic studies and new fossil evidence have yielded fundamental insights
into the pattern and timing of dinosaur evolution and the emergence of functionally modern …

Angiosperms first appeared in northern Gondwana during the Early Cretaceous,
approximately 135 million years ago. Several authors have hypothesised that the origin of …

Although sauropods played a major role in terrestrial ecosystems during much of the
Mesozoic Era, little effort has been directed toward diagnosing Sauropoda and establishing …

Sauropoda is among the most diverse and widespread dinosaurlineages, having attained a
near‐global distribution by the MiddleJurassic that was built on throughout the Cretaceous …

Titanosauriforms represent a diverse and globally distributed clade of neosauropod
dinosaurs, but their inter-relationships remain poorly understood. Here we redescribe …

A data-matrix of 205 osteological characters for 26 sauropod taxa is subjected to cladistic
analysis. Two most parsimonious trees are produced, differing only in the relationships …

Most recent studies of dinosaur phylogeny have concentrated on theropods and
ornithischians. As a result, the evolutionary relationships of sauropod dinosaurs are poorly …

Titanosauriformes was a globally distributed, long-lived clade of dinosaurs that contains
both the largest and smallest known sauropods. These common and diverse …

The Cretaceous terrestrial strata of the Neuquén Basin (northern Patagonia, Argentina) are
described together with their tetrapod records. Six local tetrapod assemblages are identified …
