Ceratosaurus ("horned lizard") was a large predatory theropod dinosaur from the Late Jurassic Period, found in the Morrison Formation of North America, and Portugal. Its name comes from the blade-like horn on its snout.

Ceratosaurus first made its appearance in "Bloodiest Battle", alongside other Jurassic dinosaurs, and later in "Hunter Becomes Hunted". It also had a cameo appearance in "Cannibal Dinosaur" and "Biggest Killers" episodes, because it was the ancestor of Majungasaurus and its cousins and was mentioned as such.

In "Bloodiest Battle", a lone Ceratosaurus was hunting for food. It comes across a female Stegosaurus with a juvenile stuck in the mud. The dino begin to eat the juvenile Stegosaurus alive until a gang of three Allosaurus arrived at the scene to eat the Stegosaurus. The Ceratosaurus fought back against two of the Allosaurus for its prey but was killed by being launched into the air and breaking its spine by the third Allosaurus.

In "Hunter Becomes Hunted", two mated Ceratosaurus were hunting in the territory of an Allosaurus. As they were hunting, the bigger predator ambushed the female, crushing her spine and windpipe in its jaws. The male fights back at the Allosaurus by slashing at its face with his sharp claws and biting its back. The Allosaurus snatches the Ceratosaurus and breaks his back by slamming him into a tree.

DescriptionEdit

Ceratosaurus stood 13 feet (4 meters) tall, measured 20 feet (6 meters) long, and weighed 1.5 to 2 tons. It had a distinctive horn (actually an expanded nasal crest) on its snout and two smaller ones on its brow--its name means horned lizard--and a row of bony plates down the middle of its back. Another horned meat-eating dinosaur was Carnotaurus sastrei, a relative of Majungasaurus and probably the most famous of the abelisaurid family and a possible descendant of Ceratosaurus.

Fighting styleEdit

Being about half the size of its contemporary rival Allosaurus, Ceratosaurus was still a fierce meat-eating hunter. Its four-fingered hands (primitive for theropods) ended in sharp claws and it killed its prey with large blade-like teeth. However, it was an ambush predator and wasn't normally a dinosaur that would engage in a fight. Despite this, Ceratosaurus would fight another dinosaur depending on circumstances.

DietEdit

Ceratosaurus may have hunted in groups and evidence suggests that it competed with Allosaurus for prey, including herbivores such as iguanodonts, stegosaurs and even the giant sauropods. Ceratosaurus, however, was more primitive in size, intelligent, and hunting habits compared to most predatory dinosaurs of its time and place and more often hunted in pairs rather than in whole packs.
