Researchers have unearthed two dinosaur "mummies" in the badlands of Wyoming, confirming duck-billed dinosaurs had hooves, alongside a string of other discoveries.

The skeletons of a duck-billed dinosaur found more than 100 years ago are so well-preserved that they contain fleshy body parts embedded in thin layers of clay.

Long before horses thundered across the plains, a plant-eating giant with hooves of its own left footprints in the mud. Newly described fossils of Edmontosaurus annectens—a duck-billed dinosaur that roamed North America 66 million years ago—show that this gentle giant had flexible skin crests,

It’s been more than 60 million years since duck-billed dinosaurs roamed around what is now known as western North America. Or, more accurately, since they clomped around. On their hoofs.

Argentinian scientists have found fossilized bones of one of the world's oldest dinosaur species in the Andes Mountains, the CONICET research agency announced on Wednesday.

To gain a better understanding of the creature, a team at the University of Chicago led by anatomist Paul Sereno tracked down the historical locations of previous dinosaur finds in east central Wyoming.

Tributes have been paid to an islander who discovered evidence of dinosaur footprints in the Isle of Skye as a schoolboy. Dugald Ross, who has died at the age of 68 following a period of ill health, made the discovery years before they were officially recognised as fossils in the 1980s.
