The P ermian and T riassic were key time intervals in the history of life on E arth. Both
periods are marked by a series of biotic crises including the most catastrophic of such …

The Ginglymodi is one of the most common, though poorly understood groups of
neopterygians, which includes gars, macrosemiiforms, and “semionotiforms.” In particular …

Abstract The Australian Mesozoic fish fauna is considered to be depauperate in comparison
with fish faunas in the Northern Hemisphere. However, due to its geographical location as a …

Few studies paid attention to the Permian and Triassic vertebrates from the Iberian
Peninsula and a re-evaluation of these faunas is needed in order to compare them with …

Gondwanan sedimentary deposits preserve a rich archive of Triassic non-marine vertebrate
evolution. This fossil record is integral to understanding early Mesozoic global change …

Neopterygii is a taxonomically diverse group of ray-finned fishes, including Teleostei,
Holostei and their closely related fossil taxa. Here, a new small-sized stem-neopterygian …

Neopterygii is the largest clade of ray-finned fishes, including Teleostei, Holostei, and their
closely related fossil taxa. This clade was first documented in the Early Carboniferous and …

The morphological disparity of species within major clades shows a variety of trajectory
patterns through evolutionary time. However, there is a significant tendency for groups to …

The Jurassic is an important period for understanding the origin of modern fish faunas, since
it saw the first radiation-and in some cases the origin-of most modern groups. In …

We present a multidisciplinary study of the Potrerillos Formation at the Quebrada del
Durazno locality, Cuyana Basin, central-western Argentina, providing novel information on …
