Carnotaurus

Carnotaurus, called Carnotaurs, was a species of predatory dinosaur that lived in the late Cretaceous period 75 million years ago. They appear as the primary antagonists in the 2000 Disney CG film Dinosaur. The male carnotaur is one of the two main antagonists (the other being Kron) while the female is the secondary antagonist.

Physical Description
The Carnotaurs are vicious-looking, meat-eating dinosaurs with red scales, large tails, sharp teeth, and short horns. The larger Carnotaur is obviously male, while the smaller Carnotaur is female.

Personality
Not necessarily evil, they are predators who need food and water. This is the main reason for the confrontation in the film; they have no real malicious intent. They just care about feeding themselves and go to the midals and just show respect for themselves and no one else, but they are, smart as they follow the clan to find water. The two in the movie might be a mated pair, as they have a very strong bond and the surviving one shows a powerful grudge against Aladar, trying to drag him over a cliff even when it was obvious the Carnotaur would die, after the other one was crushed by rocks Aladar's friends caused to fall on it.

Even so, they are infamously vicious, dangerous, and feared, described as a "mouthful of teeth with a bad attitude" by Eema.

Dinosaur
A Carnotaurus first appears in the very beginning of the film where a young Parasaurolophus chases a flying lizard into the jungle. It then looks up to where the reptile is, but before it can get close, saliva falls on the branch which caused the young dinosaur to look up where the Carnotaur eventually awakens. The young parasaurolophus starts running out of the jungle which causes attention to many of the herbivorous dinosaurs. As it starts running, the Carnotaur soon bursts out of the trees and starts chasing all the dinosaurs, and eventually kills a Pachyrhinosaurus.

At the middle of the film, two Carnotaurus, the larger one presumbly the same one from the beginning of the movie, scare off a pack of Velociraptors. The pair then go after the herd in which Aladar and his lemur family and dinosaur friends are in by following the tracks left behind.

A little later, Bruton and a scout are attacked by the Carnotaurus. Bruton escapes to warn Kron, albeit being injured, as the scout is killed by them. As soon as Bruton tells Kron, he is left behind to fend for himself.

Later as Aladar, his family and friends, and Bruton take shelter from a rainstorm in a cave, the Carnotaurs attack. Bruton comes to the rescue and sacrifices himself by causing a cave-in, killing the smaller Carnotaur, but the larger one survives, leaves and roars, apparently in rage at the loss of its companion.

After Aladar and company find the Nesting Grounds, Aladar rushes back to warn Kron's herd about the rock pile blocking the main entrance. On the way there, he see a dead dinosaur (Stygimoloch) and soon flees when he hears the Carnotaur coming and eating the Stygimoloch.

Aladar then warns Kron and the herd about the approaching Carnotaur, but Kron doesn't listen to him as he thinks he's leading it right to the herd. After his battle with Kron, Aladar assumes the herd's leadership, then the Carnotaur arrives and the herd panics. Aladar states that they should stand together, or the Carnotaur would pick them off, in which they do and the Carnotaur backs off. Then, the Carnotaur sees Kron and runs after him with Neera and Aladar not far behind. After Kron climbs the rocks and finds a cliff, the Carnotaur corners him. Kron fights back, but the Carnotaur bites him in the back and tosses him against a rock. As it is about to finish him off, Neera comes and shoves the Carnotaur in an attempt to save her brother, but is easily overwhelmed. Then when the Carnotaur was about to kill Neera, Aladar arrives, and manages to push the Carnotaur to the edge of the cliff and the Carnotaur's weight causes the cliff ledge to crumble. As the cliff starts to crack, the Carnotaur grabs Aladar and tries to pull him down with it, but fails and the Carnotaur falls off the cliff to its death.

DINOSAUR
In the ride DINOSAUR at Disney's Animal Kingdom, a Carnotaurus is encountered four times. The first time is when the Time Rover's computer locks onto a large dinosaur, although it's not the Iguanodon, the dinosaur meant to be captured. It roars at the riders, but they safely get away.

In the second encounter, lightning flashes to reveal the Carnotaurus. As it runs towards the guests, the Time Rover flees. After turning left and right many times, the Carnotaurus is encountered again, rearing to its full height and roaring loudly. Luckily, the riders in the Time Rover escape.

The last encounter is just seconds before the killer asteroid hits the Earth. The Carnotaurs lunges at the guests just as they make it through to the present day.

In Real Life
Carnotaurus is known by a single but well-preserved skeleton, it is one of the best-known theropods in the Southern Hemisphere Carnotaurus was part of the group of theropods (meaning "Beast Feet") known as the Abelisauridae (meaning "Abel's lizards") and its sub-group/family Carnotaurinae. One similar Carnotaurinae relative was the Aucasaurus although more derived in some ways, such as its extremely reduced arms and almost total lack of fingers. According to the classification of Carnotaurinae there are 10 members (With the Sub-family Carnotaurinae, Brachyrosta and Tribe Carnotaurini combined).

Trivia

 * In Dinosaur, Carnotaurus was shown to be much bigger than it was in real life. The film shows it to be at least as big, if not bigger, than Tyrannosaurus Rex. In actuality, Carnotaurus was smaller; about 10 feet tall and 26 feet long (while Tyrannosaurus was 16 feet tall and 40 feet in length), thus making it smaller than Iguanodon, the main dinosaur of the movie.
 * According to the behind-the-scenes features on the DVD, the Carnotaurus is at least 18 feet tall in the movie.
 * During the production of DINOSAUR, original plans called for Tyrannosaurus Rex, but Disney decided to incorporate the less popular Carnotaurus instead, resembling the devilish appearance as the main antagonist.
 * Many fans and viewers often mistake the Carnotaurus portrayed in the film as T-Rex due to their large size. They even nearly resemble a devil-like T-Rex in appearance.
