Carnotaurus is the only known carnivorous bipedal animal with a pair of horns on the frontal bone. [45] The use of these horns is not entirely clear. Several interpretations have revolved around use in fighting conspecifics or in killing prey, though a use in display for courtship or recognition of members of the same species is possible as well.

Carnotaurus - Natural History Museum
