Centrosaurus (Planet of Dinosaurs)

This Centrosaurus is one of the inhabitants on an unspecified planet.

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.
