Their limbs were very robust and the arms were stout. They were a reddish-brown color. Binocular vision allows animals to see three-dimensional objects more clearly, even when the objects are motionless or camouflaged. Feathers are rarely preserved in the fossil record, so they haven't been found on a T. rex specimen. What are the advantages of craft scissors? WebAnswer (1 of 5): "Don't move!
