The Mesozoic era, meaning “middle life”, is a division of earth’s history spanning from around 252 to 66 million years ago. It is subdivided into the Triassic, Jurassic and Cretaceous periods. The beginning of the Mesozoic is characterised by a long phase of recovery following the end Permian mass extinction. The end of the Mesozoic is marked by the Cretaceous/Paleogene extinction event which wiped out the dinosaurs among other groups.

Episode 60: Determining Diet

Published on March 4th, 2016 | by Joe Keating

Diet is perhaps the most important aspect of ecology. As such, understanding the diet of extinct animals is crucial if we wish to reconstruct the ecosystems of the past. However, determining what was on the menu [&hellip... Read More

Baby Chasmosaurus

Published on January 18th, 2016 | by Liz Martin-Silverstone

Juvenile dinosaurs are less common than adults, and typically not as well preserved due to the fact that their bones are often not fully formed (many of them are still cartilaginous) or fused (sutures are still [&hellip... Read More

Episode 58: Animal biomechanics

Published on January 15th, 2016 | by Liz Martin-Silverstone

One of the most difficult aspects of palaeontology is understanding how extinct animals moved around. It’s one thing to find a fossil and reconstruct it’s morphology, but it’s completely another to put that morphology into action [&hellip... Read More

Episode 55: Pterosaurs

Published on November 15th, 2015 | by Liz Martin-Silverstone

Pterosaurs were the first vertebrates to achieve powered flight, and lived in the skies above the dinosaurs during the Mesozoic. They’re often mistakenly identified as dinosaurs, but are in fact a separate, closely related group. This [&hellip... Read More

Aquatic adaptations in crocodylomorphs

Published on November 9th, 2015 | by Liz Martin-Silverstone

Crocodylomorphs today are not thought to be the most diverse group, consisting of all semi-aquatic forms of alligators, crocodiles, and gharials. However, the fossil record shows us that this group has a very long and diverse evolutionary [&hellip... Read More
