Utahraptor is a genus of dromaeosaur dinosaur. They are the biggest raptors yet discovered. Utahraptors grew up to 26 feet long and 6.6 feet tall. They could weigh up to one ton. Utahraptors, like other dromaeosaurs, hunted in packs. Utahraptor probably could have killed any prey it desired, except heavily-armoured prey like Clubtails or very large prey especially, though if necessary the Utahraptor would attack giant Longnecks.

Utahraptor in The Land Before Time

Utahraptors have appeared in the Land Before Time franchise, but are most often mistaken for Velociraptors, which have only appeared in The Land Before Time III: The Time of the Great Giving as of date. They also are incorrectly portrayed as having two claws, instead of three they closely resemble the Deinonychus which appeared in The Land Before Time VII: The Stone of Cold Fire. They stood about 9.8 feet tall and measured 7 meters long. Two Utahraptors have appeared in The Land Before Time XI: Invasion of the Tinysauruses. They chase the Tinysauruses through a cavern. Then the Tinysauruses hide in a rock pile and lose the raptors, which were heading for the Great Valley. When they reach the valley, they are first encountered by Littlefoot's friends, who are looking for him as they are apologizing for being mean to him. The Utahraptors attack them and Littlefoot. As one goes after Cera, Tria saves her. Then Ducky got chase by the purple one and got hit by a swunged branch by Littlefoot behind the tree. The blue Utahraptor chases Spike & Petrie and first got pecked in the face and tickled by Lizzle & Skitter. The purple Utahraptor chases the others and confronted by his ability to strike by Tria plus Topsy who showed up with bravery and courage and it got thrown off into the air. The blue one continues biting on LIzzle & Skitter but accidentally bit on the tail instead. Then the Tinysauruses jump on them, but are then thrown off. Daddy Topps confronts the Utahraptors, and then every member in the Great Valley comes and chases them away. Utahraptor was later seen in The Land Before Time XIII: The Wisdom of Friends were a entire pack was being chased by an Albertosaurus. The Utahraptor later became one of the main antagonists in the TV Series as subordinates of a Tyrannosaurus named Red Claw.
