恐竜説明：

Dromaeosaurus has been described as 'the original raptor'. It was first discovered in the dinosaur‑rich Judith River deposits of Alberta in Canada, but further material has since been unearthed in Montana in the USA. Dromaeosaurus was a small, very agile meat eater. However, it had quite a large brain‑case and big eyes. The mouth was armed with numerous razor‑sharp teeth that were serrated along the edges.

Although a lightweight, Dromaeosaurus was quite well built, with long arms and fingers that ended in vicious, curved claws. The hind limbs were also quite long, with a well‑developed, dagger‑like claw on the second toe of each foot. It is unlikely that this little dinosaur would attack animals much larger than itself, but if it hunted in packs then the results would be quite devastating. The dromaeosaurs were noted for their long, stiff tails. Together with good sight and a relatively high intelligence, they were effectively the wild dogs or wolves of the Age of Dinosaurs.
