Spicasaur

Overview
Unlike on Earth, dinosaurs are recent evolutions. The Spicasaur is one of the most recent.

Daily Life
Spicasaurs, though rarely eaten, are not carnivores. They are covered in spikes all over their body. The blade on their tail is their most formidable weapon. Being lithovores, they are not often feared by other creatures, but the smarter ones avoid their spikes.

Adaptations

 * They evolved from a similar dinosaur without any spikes.
