If dinosaurs couldn't pronate their hands, then does the idea of Theriznosaurs being Mesozoic giant ground sloths fall apart? I think it would be hard to pull down a branch if you couldn't hook your claws around a branch

They could probably do so from the side; pronation isn't a requirement for such an activity
