Dromaeosaurus was a genus of non-avian theropod dinosaur that belonged to the family Dromaeosauridae (which the name prior to the creature itself). Like most dromaeosaurs, it was fast and agile and had three clawed hand talons, it also had a sickle-like claw that protruded from the second-toe digit which was used to for attacking prey and possibly climbing trees, but unlike most dromaeosaurs that proceed it; it had a more stocky build and a more robust skull along with a small number of teeth (9 being the estimated amount) which were rather large (in most cases as raptors usually slender teeth and have a diverse number).
Dromaeosaurus was discovered in the early 1900's near what is now known as the Dinosaur Park formation, dating back to the Campanian stage of Late Cretaceous period about 75 million years ago. As far as size goes, the Dromaeosaurus was much like the typical dromaeosaur measuring about 2 meters (6ft) in length and standing less than 1 meter (around 3ft) tall. It was one of the last dromaeosaurs to live on Earth before the mass extinction that killed the dinosaurs.
