Proceratosaurus

Proceratosaurus was a carnivorous theropod dinosaur native to Middle Jurassic Europe. Its name means "horned lizard" and refers to the horn on its nose. However, it is not related to Ceratosaurus, but to a close relative of Ornitholestes. It was a much more graceful and delicate animal. 

Proceratosaurus was a small predatory theropod dinosaur of the same size as Deinonychus. It had a slender body and a characteristic crest on its snout. It lived alongside other theropods, including Megalosaurus. 

It was known from a single fossil skull of a subadult individual. The skull had internal air spaces and D-shaped front teeth typical of all tyrannosaurs. It lived in what is now England, Europe, during the Middle Jurassic.

Proceratosaurus was a friendly dinosaur that needed to be kept in small groups. They hunted hadrosaurs and other tame herbivores and fought with other small carnivores. It was a bipedal animal with a long, sharp tail, strong arms with three fingers on each hand, and long legs with three toes on each foot.

Proceratosaurus had a sharp serrated tooth that could crunch through bone. It reached 3 meters long and weighed between 28 and 36 kilograms, which made it small compared to the T. rex.
