Therizinosaurus was a large, feathered theropod from the Late Cretaceous, famous for its meter-long claws and unusual plant-eating diet, which has made it a favourite in dinosaur documentaries, games and fan edits. Roar clips like this one circulate as standalone sound effects for creators who need a creature voice that is not a generic T. rex or lion roar. They are commonly dropped into Jurassic-inspired videos, survival games, animations and meme edits, where a distinctive prehistoric bellow helps a fictional beast feel original rather than recycled.
