Here, we describe the dicynodont Lisowicia bojani, from the Late Triassic of Poland, a gigantic synapsid with seemingly upright subcursorial limbs that reached an estimated length of more than 4.5 ...

Fossil skull of the extinct cynodont therapsid Cynognathus crateronotus. Cynognathus was a powerful predator that was close to being a mammal, but not quite. It has been found in several parts of ...

Infographic showcasing the differences in jaw functional anatomy and body size and the potential ecological inferences found in the study of more mammal-like behaviours among ancient predatory ...

Researchers compared modern and ancient animals to explore how mammalian vertebrae have evolved into sophisticated physical structures that can carry out multiple functions. The comparison between ...

Mammals are familiar beasts. From a squirrel on a power line to a blue whale swimming through the sea, we share the world with more than 6,000 mammal species of all shapes and sizes. While we can ...

At least 180 million years ago, when dinosaurs roamed the Earth, reptiles with mammal-like features existed near Lake Powell. In March 2023, paleontologists discovered bonebeds in the Navajo Sandstone ...

Over 300 million years ago, our ancestors diverged from the ancestors of reptiles and began the evolutionary journey towards becoming mammals. What were these earliest ancestors like? For one, they ...

A mathematical model of the mechanical arrangement of the lower jaw and the external adductor muscle is constructed which shows that it is unlikely that a coronoid process was initially developed by ...

The evolutionary success of the first large predators on land was driven by their need to improve as killers, researchers suggest. The evolutionary success of the first large predators on land was ...
