Carnotaurus
Carnotaurinae is a subfamily of Abelisaurid theropod dinosaurs that usually have 1 horn on each side of their head, and very short arms, along with small snouts with a mouth that contains teeth.
Description[]
Carnotaurines may have hunted in packs, and their horns and crests potentially were used as weapons or in courtship. Their arms weren’t that useful but may have been used for mating purposes.
