Researchers measure how long it takes for DNA from bone to degrade, confirming that genetic information from dinosaurs could not last to the present day.

A small but vicious-toothed dinosaur may have dined mostly on plants, challenging the idea that fangs are hallmarks of carnivores.

The leading argument for dinosaurs being cold-blooded is overturned as a nearly identical bone structure is found in mammals.

Researchers discover a 70-million-year-old egg that belonged to a small, bird-like meat-eating dinosaur.

A 130 million-year-old winged dinosaur offers scientist the oldest evidence of iridescent feathers.

Fossilized fleas dating as far back as 165 million years provide clues of early flea evolution.

A 19th century geologist and minister investigates a prehistoric cave full of hyena bones in his native England.

Dinosaur and early bird feathers trapped in amber around 80 million years ago provide unprecedented insight into the evolution of plumage.

After rummaging through thousands of amber inclusions housed at the University of Alberta and the Royal Tyrrell Museum of Paleontology in Canada, researchers discovered 11 amber encased-feather fossils that provide the most detailed picture yet of early feather evolution.

The discovery of a new bird-like fossil challenges longstanding theories about which species of dinosaur gave rise to the avian lineage.

Evidence that large dinosaurs had body temperatures similar to modern-day mammals suggests they were either endothermic or extremely good at conserving body heat.

University College London researcher Mike Taylor recounts the discovery of a new dinosaur with unusually powerful thigh muscles. Read the full story.

A closer look at some dinosaur bones accumulating dust since their 1994 discovery reveals a new, athletic sauropod species.
