- Discovery: As its name suggests, Dromaeosaurus was one of the first dromaeosaurid dinosaurs to ever be discovered. It lived during the Late Cretaceous period, and the first specimen was recovered by palaeontologist Barnum Brown, during 1914 from Alberta, Canada. This specimen consisted of a partial skull, two neck bones, one metacarpal and some foot bones. In addition to this original specimen, several other skull fragments, and about thirty isolated teeth are known from subsequent discoveries in Alberta and Montana, Canada.
- Statistics: The lack of a complete specimen has made creating length and weight estimates for Dromaeosaurus very difficult. Based on the length of the skulls found, and comparison with other, better known dromaeosaurids, it is belived Dromaeosaurus would have grown to lengths of around 1.8 metres and weighed only 15kg.
- Description: Despite being the first dromaeosaurid dinosaur to be discovered, very little is known about Dromaeosaurus. Full skeletal reconstructions have only been made possible thanks to knowledge gained from other, more recently discovered, dromaeosaurids. Although Dromaeosaurus still had the sickle-shaped claws on its feet, its skull was larger and much more powerful than those of other dromaeosaurids. In addition, the teeth of Dromaeosaurus appear to be more heavily worn than those of its relatives, suggesting that its jaw was used for crushing and tearing rather than just for slicing through flesh. Recent research has suggested that Dromaeosaurus had a bite nearly three times as powerful as that of Velociraptor, suggesting that it relied more on its jaws for killing its prey, rather than its sickle-claw.
