358 million years ago, a shallow sea teeming with marine life covered Northeast Ohio. Dunkleosteus terrelli, the largest predator and one of the fiercest creatures alive in the Devonian “Age of Fishes,” ruled the subtropical waters. Up to 20 feet in length and weighing more than 1 ton, this arthrodire fish was capable of chopping prehistoric sharks into chum! Dunkleosteus had a massive skull made of thick, bony plates, and 2 sets of fang-like protrusions near the front of powerful, self-sharpening jawbones.

On November 18, 2020, the Ohio General Assembly passed a bill declaring Dunkleosteus terrelli the state fossil fish.
