Dromaeosaurus claw

Dromaeosaurus: distribution

Discovery: in Alberta and midwestern USA.
Other info: The more familiar term for these kinds of dinosaurs is ‘raptors’. The first raptors were discovered in Canada in 1914. Raptors had bigger brains compared to other carnivorous dinosaurs. Fossils found in China show prints of feathers or down which indicate that these dinosaurs may have developed wings.
