Utahraptor is a large dinosaur that lived during the early Cretaceous period, around 126 million years ago. It was a member of the dromaeosaurid family, which includes other well-known dinosaurs like Velociraptor. Utahraptor was characterized by its long, curved claws and a large, sickle-shaped claw on each foot, which it likely used for hunting. This dinosaur could grow up to 23 feet long and weighed around 500 pounds. Fossils of Utahraptor were discovered in Utah, USA, and it is considered one of the largest raptors known. Its size and features suggest it was a formidable predator in its ecosystem.
