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.

Scientists have uncovered fleshed-out imprints of a pair of hoofed dinosaurs in Wyoming. Hardened clay formed around the two young Edmontosaurs, preserving their skin contours and providing experts with unprecedented insight how they looked.

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.

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

Scientists have long debated whether dinosaurs were in decline before an asteroid smacked the Earth 66 million years ago, causing mass extinction.

Imaging technology has revolutionized paleontology, allowing scientists to study fossils that are buried deep in the rock or too small to handle. Two recent studies I was involved with show some of the technology's potential,
