A new way of looking at marine evolution over the past 540 million years has shown that levels of biodiversity in our oceans have remained fairly constant, rather than increasing continuously over the last 200 million years, as scientists previously thought. A team led by researchers from the School of […]

Predator paradise — The giant predatory dinosaur Carcharodontosaurus eyes a group of Elosuchus — crocodile-like hunters — near a carcass. Credit: Artwork by Davide Bonadonna 100 million years ago, ferocious predators, including flying reptiles and crocodile-like hunters, made the Sahara the most dangerous place on Earth. This is according to […]

An international team of evolutionary biologists and paleontologists have reconstructed the evolution […]

Reconstruction of the giant pterosaur Hatzegopteryx launching into the air, just after the forelimbs have left the ground. Credit: Mark Witton Pterosaurs were the largest animals ever to fly. They soared the skies for 160 million years–much longer than any species of modern bird. Despite their aeronautic excellence, these ancient […]

Tiny molar teeth of the parapithecid monkey Ucayalipithecus from the Oligocene of Perú. Credit: Erik Seiffert The discovery helps date the transatlantic migration to about 34 million years ago, around the time a major drop in sea level would have made the ocean voyage shorter. Four fossilized monkey teeth discovered […]

Fossil rudist bivalves (Vaccinites) from the Al-Hajar Mountains, United Arab Emirates. Beer stein-shaped distant relative of modern clams captured snapshots of hot days in the late Cretaceous. Earth turned faster at the end of the time of the dinosaurs than it does today, rotating 372 times a year, compared to […]

A team from the UK and Germany discovered forest soil from the Cretaceous period within 900 km of the […]
