"Dromaeosaurus albertensis" was a small carnivore, the size of a wolf, about 2 m (7 ft) in length and 15 kg (40 lb) in weight. Its mouth was full of sharp teeth, and it had a large "sickle claw" on each foot. It lived during the Upper Cretaceous: some teeth which may belong to it have been found from the latest Cretaceous, 65.5 million years ago.
