Carnotaurus

Carnotaurus is very well known for it's two large horns sticking out of the top of it's head. They belong in a group called Abelisaurs (Abel's Lizard) Carnotaurus means Meat Eating Bull in Greek. These guys have very VERY tiny arms smaller than that of Tyrannosaurus and they certainly did not move at all which they would be considered useless. On each arm contains 4 different finger such as a Claw, Clawed finger, finger and a Nub. Their use for their horns are mostly for display and to scare off rivals. Carnotaurus are smaller than Tyrannosaurus so they aren't as terrifying as you think. Carnotaurus is closely related to Rugops, Majungasaurus and many other Abelisaurs.
