Marine reptiles and mammals are phylogenetically so distant from each other that their
marine adaptations are rarely compared directly. We reviewed ecophysiological features in …

The colonisation of freshwater and marine ecosystems by land vertebrates has repeatedly
occurred in amphibians, reptiles, birds and mammals over the course of 300 million years …

Finely preserved fossil assemblages (lagerstätten) provide crucial insights into evolutionary
innovations in deep time. We report an exceptionally preserved Early Triassic fossil …

INTRODUCTION The iterative evolution of secondarily marine tetrapods since the Paleozoic
offers the promise of better understanding how the anatomy and ecology of animals change …

Secondary aquatic adaptations evolved independently more than 30 times from terrestrial
vertebrate ancestors,. For decades, non-avian dinosaurs were believed to be an exception …

The timing of the end-Permian mass extinction and subsequent prolonged recovery during
the Early Triassic Epoch can be established from astronomically controlled climate cycles …

Despite their profound adaptations to the aquatic realm and their apparent success
throughout the Triassic and the Jurassic, ichthyosaurs became extinct roughly 30 million …

One of the key faunal transitions in Earth history occurred after the Permo-Triassic mass
extinction (ca 252.2 Ma), when the previously obscure archosauromorphs (which include …

The Triassic has long been recognized as a time during which marine and terrestrial
ecosystems modernized dramatically, and it seems to have been a two-step process. First …

BACKGROUND More than 30 different lineages of amphibians, reptiles, birds, and
mammals have independently invaded oceans ecosystems. Prominent examples include …
