Maxillae and a lacrimal (the main tooth-bearing bones of the upper jaw, and the bone that forms the anterior margin of the eye socket, respectively) recovered from the Bayan Mandahu Formation in 1999 by the Sino-Belgian Dinosaur Expeditions were found to pertain to Velociraptor, but not to the type species V. mongoliensis.
The Fighting Dinosaurs is a fossil specimen which was found in the Late Cretaceous Djadokhta Formation of Mongolia in 1971. It preserves a Protoceratops andrewsi and Velociraptor mongoliensis trapped in combat about 74 million years ago [1] and provides direct evidence of predatory behavior in non-avian dinosaurs. The specimen has caused much ...

A Velociraptor mongoliensis skull bears two parallel rows of small punctures matching the spacing of teeth in Velociraptor, so the injury was probably received in combat with another V. mongoliensis. Because there was no sign of healing, the researchers who first reported the injury concluded it killed the afflicted animal. [41]
Since dinosaur teeth are often found with well-preserved enamel, Reisz concluded that dinosaurs likely had a protective set of lips to hydrate the gums. Reisz also examined the gums, teeth and ...
Dinosaur teeth have been studied since 1822 when Mary Ann Mantell (1795-1869) and her husband Dr Gideon Algernon Mantell (1790-1852) discovered an Iguanodon tooth in ...
