This planet once played host to a massive dinosaur that packed more than 500 teeth into its jaws. That might sound like a terrifying prospect at first, but the creature in question wasn't a vicious ...

Fossilized dinosaur teeth can reveal a lot more than just how these creatures ate and who they were related to – they can also tell us what the air was like in prehistoric times. As it turns out, ...

AUSTIN (KXAN) — Ancient titans once roamed the Earth, consuming plants and animals in order to survive. A new study from the University of Texas is helping paint a picture of ancient life by looking ...

What did long-necked dinosaurs eat—and where did they roam to satisfy their hunger? A team of researchers has reconstructed the feeding behavior of sauropods using cutting-edge dental wear analysis.

Some dinosaurs were fussy eaters. Certain herbivorous dinosaurs preferred specific parts of plants, challenging long-standing assumptions about their diets, a study of fossilized dino teeth shows. The ...

A previously untapped source of data sheds new light on the climate of the early Earth: fossilized dinosaur teeth show that the atmosphere during the Mesozoic era, between 252 and 66 million years ago ...
