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.

A robot model of a winged but flightless dinosaur suggests the dinosaur may have flapped its wings while moving on the ground.

Fossils reveal the quick death of plants and animals from a massive surge of water after the impact 66 million years ago, which is thought to have spelled the demise of dinosaurs.

The world’s largest T. rex found to date likely weighed nearly 20,000 pounds during its life.

Galagadon’s tiny teeth look like the spaceships in its namesake video game from the early 1980s.

Charles R. Knight’s illustrations shaped the public’s view of prehistoric life.

See an update from Chicago's Field Museum about the works of Charles R. Knight and other paleoartists who pioneered the depiction of ancient life.

A controversy over pterosaurs’ plumage has taken off, with a new discovery pushing feather origins back 80 million years into the early Triassic.

While shifts in behavior could help wildlife and people coexist, they might also affect the animals’ survival.

Nutrient-rich water helped marine organisms reinhabit Chicxulub crater relatively quickly after the mass-extinction event.

A mass extinction event from an asteroid hitting Earth wiped out forests and, concurrently, tree-dwelling birds.
