The early dinosaurs were faster and more dynamic than their competitors, according to a study led by University of Bristol researcher Amy Shipley.

Crocodylians are surviving members of a 230-million-year lineage called crocodylomorphs, a group that includes living crocodylians (i.e. crocodiles, alligators and gharials) and their many extinct relatives.

Paleontologists in the United States have described a new genus and species of extinct crocodile relative based on a partially articulated skeleton found in the Middle Triassic Fossil Hill Member of the Favret Formation in Nevada.

Saurosuchus galilei is a large loricatan pseudosuchian archosaur that lived in South America 230 million years ago (Late Triassic epoch).

A new genus and species of large-bodied aetosaur that lived some 218 million years ago has been described from a significant portion of carapace found in Texas, the United States.

Volcanic winters impacted the late Triassic biodiversity, but prototypical feathers insulated dinosaurs from the cold.

Dinosaurs came to flourish during the Jurassic period after a volcanic eruption roughly 201 millions years ago wiped out many marine and land animals, leaving them able to evolve and grow. Now, further details about this eruption and the mass extinction have been revealed. A group of researchers demonstrated how low temperature magma slowly heated sedimentary rocks, causing high sulfur dioxide and low carbon…

Learn why a comprehensive comparison of crocodile skulls, teeth, and jaws hints that generalists, not specialists are best built for longevity.

Dinosaurs may have ruled Earth for over 160 million years because the way they walked gave them a big advantage during the drying climate of the Triassic.

The apex predators that roamed the earth 230 million years ago had a much weaker bite than previously thought, and likely couldn't crunch through bone to consume the entirety of their kills.

Their eating habits may have kept them from suffering the same fate as the dinosaurs.

Dinosaurs get all the glory. But aetosaurs, a heavily armored cousin of modern crocodiles, ruled the world before dinosaurs did. These tanks of the Triassic came in a variety of shapes and sizes before going extinct around 200 million years ago. Today, their fossils are found on every continent except Antarctica and Australia.
