Therizinosaurus was a giant herbivorous dinosaur that lived during the Late Cretaceous period. It was known for its long, sharp claws, which could grow up to 3 feet in length. Therizinosaurus had a large, bulky body and stood on two legs, reaching heights of up to 10 meters. Despite its intimidating appearance, Therizinosaurus was a peaceful herbivore, using its claws to strip leaves from trees. It is believed that Therizinosaurus may have used its claws for self-defense against predators as well.
