T-Rex

It's a long-accepted fact that T-Rex the dinosaur couldn't see you if you didn't move. However, that left the question of how you could possibly hope to remain unnoticed given you would be screaming your lungs out! Research published recently in New Scientist suggests this may not have been a problem ... T-Rex may have been hard of hearing and (bonus) not able to hear high-pitched sounds. But we know T-Rex wasn't the dinosaur with the worst hearing - that would have been Stegosaurus - with its horns (as in hearing - boom tish!) (It's at times like this that I'm really sorry I can't draw. I would have loved to have an image of a T-Rex with a hearing horn held up to its ear with those "ridiculously short arms" [thanks Rowan], here!)
