Fighting Dinosaurs

Common card · No. 248318

The Fighting Dinosaurs is a fossil specimen 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. The specimen has caused much debate as to how both animals came to be preserved together with relative completeness. Several hypotheses have been proposed, including a drowning scenario, and burial by either dune collapse or sandstorm.
