Stegosaurus (Planet of Dinosaurs)

This Stegosaurus is one of the inhabitants on an unspecified planet from the Planet of Dinosaurs Universe. Only one was shown, it being killed by a Tyrannosaurus.

Description
While it physically resembles an earth Stegosaurus, its tail is notably a lot more loose and fluent in movement, and its sails are also not as rigid, and can bend surprisingly easily.
