Paradoxides pinus is a form of trilobites that thrived all over the world during the middle of the cambrian period as per index fossils. Structurally, they are found to possess semi circular like head with the cheeks curving into structures that resemble spines. Their eyes are sickle shaped for they are believed to have all round vision. The exoskeleton is large and often flattened or oval in shape with greatest width along the re-curved spine.
