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.

Scratches on dinosaur teeth could reveal what they really ate. Dental microwear texture analysis (DMTA) has now been used to infer the feeding habits of large theropods, including Allosaurus and T.

A collection of dinosaur teeth hailing back to the Cretaceous and Jurassic periods has given scientists a new window into the world's prehistoric climate. By studying an isotope of oxygen in the ...
