Learn how fossils from Arizona’s Petrified Forest National Park revealed that a Late Triassic crocodile relative may have started life on four legs before walking on two as an adult.

The biggest mass extinction of all time happened 251 million years ago, at the Permian-Triassic boundary. Virtually all of life was wiped out, but the pattern of how life was killed off on land has ...

Teaching faculty in the University of Wisconsin Integrative Biology Department Scott Hartman spoke on how thermal modeling is an effective tool for predicting the End-Triassic Extinction period Sept.

In a review, published today in the journal Frontiers in Earth Science, scientists reveal that predators became meaner and prey animals adapted rapidly to find new ways to survive. On land, the ...

A Triassic herbivore, known for its supposed similarities to a modern-day ostrich, has been revealed to have entirely different approach to feeding from previously thought. A Triassic herbivore, known ...
