Footprints in southern Africa’s Karoo Basin show mammals and dinosaurs navigating a “land of fire,” as researchers describe the volcanic landscape.

Carbon cycle modeling and paleotemperature records argue that an asteroid impact—not volcanic fumes—was the main driver of the dinosaur die-off.

As dinosaurs got smaller, their metabolism increased, paving the way for bird evolution.

These ancient insects ate dinosaur feathers during the Cretaceous period.

The site, Corral Bluffs in Colorado, also reveals how plants evolved and how ecosystems rebounded after the asteroid impact.

The answer has broad implications for paleontology research—and maybe for museum collections, too.

A study fails to detect ancient proteins among the microbes, adding to the debate about whether peptides can survive tens of millions of years underground.

Paleontologists find a fossil of a dinosaur, Ambopteryx longibrachium, with membranous wings, in China.

Fossils of two dinosaur skeletons found in New Mexico are from a species new to science that lived 92 million years ago.
