If you ride Dinosaur any time soon, look for the hidden dino when your vehicle stops at the first Carnotaurus. Look behind and to your left and you can see one of the spare carnotaurus heads sitting amongst the bushes. This is one of the non-animatronic figures that they use to fill in gaps when the other dinos go out for rehab. There are two of these - the one visiible is the head and neck, there is another one that is smaller and is just the head.
