Geologist Scott McKenzie has been collecting and assembling parts of the shark-eating Dunkleosteus for several years.

Swimming in the oceans 370-360 million years ago, Dunkleosteus was a powerful predator. With two blades instead of teeth, it consumed anything and everything from sharks to fish and even its own kind.

There have been recreations of its head, nearly five feet long, but McKenzie hopes to eventually recover the whole body.
