Centrosaurus (Planet of Dinosaurs)

This Centrosaurus is one of the inhabitants on an unspecified planet from the Planet of Dinosaurs Universe. The creature only makes one appearance throughout the film, and is responsible for one notable death.

Description
Physically, the Centrosaurus is a large creature, resembling a ceratopsian to a large extent. Its mouth though is larger, and longer than a standard ceratopsian of Earth, with a singular large horn, a set of horns growing from its frill, and its skin is strong enough to withstand laser beam shots. Their horn is strong and durable enough to spear a human being completely without effort.

While normally docile, they can be easily agitated and highly aggressive.
