Q What were the enormous claws of Therizinosaurus most likely used for?

Although Therizinosaurus belonged to the theropod group, which includes carnivorous dinosaurs, it had a diet that was largely plant-based.
Its enormous forelimb claws may have been used to pull down branches or gather vegetation.
Another theory suggests that the claws served as a means of defense against large carnivorous dinosaurs, but their exact function has not yet been fully understood.
