How Did Dinosaurs Deliver Bone-Crushing Bites? By Keeping a Stiff Lower Jaw.

A new study, ‘150 million years of sustained increase in pterosaur flight efficiency’, published in the journal Nature has shown that pterosaurs – a group of creatures that became Earth’s first flying vertebrates – evolved to improve their flight performance over their 150 million-year existence, before going extinct at the same time as dinosaurs 66 million years ago.

It’s not often a new mass extinction is identified; after all, such events were so devastating they really stand out in the fossil record. In a new paper, published today in Science Advances, an international team has identified a major extinction of life 233 million years ago that triggered the dinosaur takeover of the world. The crisis has been called the Carnian Pluvial Episode.
