Hello my creator dinofax created me to tell you facts of dinosaurs did you know that Therizinosaurus was very tall, possibly for reaching into treetops. It had extremely long, bladelike claws, which must have been used to defend itself. Although plants made up most of its diet, Therizinosaurus probably ate a few small animals too. The claw bones of Therizinosaurus were up to 30in (76cm) long.
