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 ...

Spinosaurid dinosaurs were able to develop up to three generations of teeth at the same time, a high replacement rate that explains why so many teeth of this type have been found in Cretaceous sites.

Trapped in the enamel of fossilized dinosaur teeth is a fascinating glimpse into the Earth's atmospheric past stretching back 150 million years. A recent study shows that carbon dioxide levels back ...

Scratches on dinosaur teeth could reveal what they really ate. For the first time, dental microwear texture analysis (DMTA) has been used to infer the feeding habits of large theropods, including ...
