Paleontologists started clearing sediment in a quiet stretch of Torotoro National Park and kept spotting track after track. The ground held footprints from creatures that moved through an ancient shoreline long before humans appeared.

The Pulaosaurus qinglong, a small herbivorous dinosaur from about 163 million years ago, was found with not only a surprisingly preserved voice box but also seeds and small stones in its stomach. This revelation offers new clues about how early dinosaurs communicated and fed—and what they might have sounded like.

Paleontologists have discovered and documented 16,600 footprints left by theropods, the dinosaur group that includes the Tyrannosaurus rex.

Few moments in paleontology are as exciting as the discovery of dinosaur eggs. These fragile and ancient specimens offer a rare and intimate glimpse into the lives of creatures that haven’t roamed the Earth for millions of years.

The Denver Museum of Nature & Science already houses a vast trove of dinosaur bones, but it recently received an unexpected addition to the collection. The latest fossil didn’t come from a generous benefactor or anonymous donor–it came from beneath the ...

"A bit like dinosaurs on Earth — they were enormous and primitive. And they had short lives, living for just a quarter of a million years."

This time reality really surpasses fantasy," said Cristiano Dal Sasso, a paleontologist at Milan’s Natural History Museum, who received the first call from wildlife photographer Elio Della Ferrera after making the discovery.
