Stegosaurus

The huge Stegosaurus, with its very sharp, spiny plates, is usually a peaceful animal in the valley of Eodon.

Description
If avoided, the Stegosaurus normally shows no interest in fighting. However, should it become angered, it is more than capable of defending itself, shredding opponents with its spiked tail. Even the mighty Tyrannosaurus avoids it when possible. In Eodon, Stegosaurus hide is used in the construction of protective shields. They are widely known as the best primitive armour available (next to the rare and highly-advanced Kotl shields).
