About Dromaeosaurus
Dromaeosaurus (; lit. 'running lizard') is a genus of dromaeosaurid theropod dinosaur that lived during the Late Cretaceous period (middle to late Campanian and Maastrichtian), sometime between 80 and 69 million years ago, in the Canadian province of Alberta and the western United States. The type species is Dromaeosaurus albertensis, which was described by William Diller Matthew and Barnum Brown in 1922. Its fossils were unearthed in the Hell Creek Formation, Horseshoe Canyon Formation and Dinosaur Park Formation. Teeth attributed to this genus have been found in the Prince Creek Formation. Dromaeosaurus is the type genus of both Dromaeosauridae and Dromaeosaurinae, which include many genera with similar characteristics to Dromaeosaurus such as possibly its closest relative Dakotaraptor. Dromaeosaurus was heavily built, more so than other dromaeosaurids that are similar in size, like Velociraptor.
