The “mesozoic cow” was a dinosaur with hundreds of ever-replacing teeth. Here’s how its uniquely adapted skull allowed it to graze like cattle on low vegetation.

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.

A newly identified tiny dinosaur, Foskeia pelendonum, is shaking up long-held ideas about how plant-eating dinosaurs evolved. Though fully grown adults were remarkably small and lightweight, their ...

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 ...

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 ...

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

New fossil find reveals a miniature dinosaur species once mistaken for a juvenile, offering fresh clues about early ...

A small but fierce jawbone sits in Argentina’s natural science museum in Buenos Aires. Six inches long and studded with backward-curving fangs that would have hooked into flesh to rip it open, the ...

The speed at which spinosaurid dinosaur teeth were replaced accounts for their overabundance in Cretaceous sites This has been confirmed by a study in which researchers from the UPV/EHU are taking ...

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 ...
