This fierce pack hunter was found in what is now the central U.S. in Wyoming during the Cretaceous period toward the end of the age of dinosaurs.
It was a large raptor about 5-6 feet tall and 8 feet long. This carnivore hunted in small packs and probably killed and ate much larger dinosaurs.
The “sickle” claws on its back feet were effective killing tools used to hunt prey.
