The Female Carnotaurus is the secondary antagonist of Dinosaur. She is smaller than her mate and is his minion.
She is a vicious-looking, meat-eating dinosaur with red scales, a large tail, sharp teeth, and short horns. She is smaller and physically weaker than her mate.
She first appears at the middle of the film when she and her mate scare off a pack of Velociraptors from the remains of a Struthiomimus. The pair then go after the herd in which Aladar, his lemur family and dinosaur friends are in by following the tracks left behind.
Later, Bruton and a scout are attacked by the Carnotaurus while searching for water. Bruton escapes to warn Kron, albeit injured, as the scout is killed by them. As soon as Bruton tells Kron, he is left behind to fend for himself, having unintentionally led the predators to the rest of the herd. That night, the Carnotaurs stop for water before noticing new tracks in the distance and resuming their hunt.
Later, as Aladar, his family, friends and Bruton take shelter from a rainstorm in a cave, the Carnotaurs inevitably discover them and attack. Bruton comes to the rescue and sacrifices himself by causing a cave-in, burying the Female Carnotaurus. The Male Carnotaurus survives, however, leaving and roaring in vengeance, before continuing his search for the herd.
