Dromaeosaurus (/ ˌ d r oʊ m i ə ˈ s ɔːr ə s,-m i. oʊ-/; [3] lit. ' running lizard ' ) is a genus of dromaeosaurid theropod dinosaur that lived during the Late Cretaceous period (middle late Campanian and Maastrichtian ), sometime between 80 and 69 million years ago, in Alberta , Canada and the western United States.
The same study also indicated that dromaeosaurids such as Dromaeosaurus and Saurornitholestes (two dromaeosaurids analyzed in the study) likely included bone in their diet and were better adapted to handle struggling prey while troodontids, equipped with weaker jaws, preyed on softer animals and prey items such as invertebrates and carrion.

Dromaeosauroides differs from Dromaeosaurus in that the cutting edge at the front side is further from the middle of the tooth. Although the tooth is larger and the denticles similar, each denticle was smaller than those of Dromaeosaurus, which had only 13–20 denticles per 5 millimetres (0.20 in), instead of Dromaeosauroides' 30.

Utahraptor is the largest known genus in the family and belongs to the same clade of other notable dinosaurs such as Velociraptor, Deinonychus, or Dromaeosaurus. It is classified in the subfamily Dromaeosaurinae , which is found in the clade Eudromaeosauria .
Although the right shape for Dromaeosaurus tooth serrations, the preserved marks are too coarse to have been left by that genus. [18] Although a specific identification cannot be made, the most likely perpetrator would be a juvenile individual of one of the Dinosaur Park Formation's tyrannosaurids, like Gorgosaurus, Daspletosaurus, or ...
