New research in a North American “mummy zone” in eastern Wyoming reveals how giant duck-billed dinosaurs were preserved in striking detail.

A paleontologist explains the latest science about Troodon formosus, and whether it was really the smartest dinosaur.

Wyoming’s “dinosaur mummies,” once thought to preserve fossilized flesh, are actually detailed clay molds formed by microbes as the creatures decayed

Edmontosaurus, which munched plants with its broad and flat snout that vaguely resembled a duckbill, roamed western North America in the Cretaceous Period.

A pair of Edmontosaurus specimens found in a Wyoming dig help researchers to understand the process that led them to be mummified.

Paleontologists may have discovered when plant-eating dinosaurs evolved their long necks after a new species of sauropodomorph was found in Argentina.

It was in egg-cellent condition. Argentine paleontologists found a real diamond in the rough after happening across a perfectly preserved 70-million-year-old dinosaur egg during an excavation.

Argentinian researchers have described a Carnian theropod with features previously thought to belong only to much later neotheropods, indicating greater early dinosaur diversity than expected as well as a possible climate-related ebb and return of dinosaur abundance in northwestern Argentina.
