Fighting Dinosaurs
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 (a ceratopsian dinosaur) and Velociraptor mongoliensis (a dromaeosaurid dinosaur) locked in combat between 75 million and 71 million years ago and provides direct evidence of predatory or agonistic behaviour in non-avian dinosaurs.
