Brontosaurus (Planet of Dinosaurs)

This Brontosaurus is one of the inhabitants from an unspecified planet. Very little is known of the creature, as it only has been encountered once in recorded study.

Physical Appearance
While mirroring the Earth Brontosaurus, this creature is more akin to the older depictions of Earth dinosaurs: a very large animal with gray, elephantine skin, and dragging its long tail on the ground.

Behavior
The Brontosaurus is a peaceful grazer, as it seemingly doesn't acknowledge smaller creatures such as Humans.
