Dromaeosaurus was a small, carnivorous dinosaur that lived during the Late Cretaceous period, around 75 million years ago. It belonged to the family Dromaeosauridae, which includes other well-known dinosaurs like Velociraptor. Dromaeosaurus was characterized by its sharp claws, long tail, and a slender body, making it an agile predator. This dinosaur measured about 6 to 7 feet long and had a distinctive sickle-shaped claw on each foot, which it likely used to catch prey. Fossils of Dromaeosaurus have been found in North America, providing valuable insights into the diversity of theropod dinosaurs during its time.
