The Utahraptors are large dinosaurs, much larger than the Deinonychus and the Velociraptors. While they have many similarities with the other two dinosaurs, they are completely different from their savage actions, that they had caused to other dinosaurs. They appear as the main antagonists in The Land Before Time installments, Invasion of the Tinysauruses and The Wisdom of Friends. They also appear in the events of Heroes vs. Villains, as part of Ogthar's dinosaur army.
