Dunkleosteus terrelli

One of the first jawed animals on the planet, this prehistoric armored fish attacked its prey with bone-crunching ferocity. Muscle Man: This fish's body was bulky and extremely muscular. It needed the muscle power to propel itself through the water when it attacked prey. Bone Head: Dunkleosteus' skull was made of several pieces of thick bone, giving it an armored plating that no other creature could break through.

Thick and fang-like in the front, they could easily chop a large victim in half. In back the "teeth" were wide and a little smoother, like molars, and used for grinding food."Protective Eyewear: To keep them safe, dunkleosteus' eyes were set inside four pieces of thick bone that formed a circular shield."
