Meat-eaters like tyrannosaurs and Velociraptors all belong to a group of dinosaurs called theropods. The teeth that they used to rip apart their fleshy prey are complex and vary in size, shape, and in ...

Dinosaur teeth discovered by a now retired quarryman have revealed a community of prehistoric predators that lived around 135 million years ago in an "exciting" discovery. Paleontologists examined ...

This dinosaur’s skull was light as air but its mouth was packed with power—and a unique ability to quickly grow teeth. Here’s how Nigersaurus was built for nonstop grazing. The cast of the skull of ...

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, ...

Dinosaurs may have vanished millions of years ago, but their teeth still carry a message from Earth’s distant past. A team of scientists from the Universities of Göttingen, Mainz, and Bochum has shown ...

Dinosaur teeth found with the help of a retired quarry worker have revealed how the fearsome tyrannosaur once roamed Bexhill-on-Sea. Research led by the University of Southampton found that several ...

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.

A previously unexploited source of information is now throwing new light on the Earth's climate during the age of dinosaurs. Fossilized dinosaur teeth show that concentrations of carbon dioxide in the ...

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 ...

Sauropod tooth scratches reveal that some dinosaurs migrated seasonally, others ate a wide variety of plants, and climate strongly shaped their diets. Tanzania’s sand-blasted vegetation left ...
