Discovered in 1867 by Dr. David Dunkle of the Cleveland Museum of Natural History, and whom it was named after, with ‘osteus’ being Greek for ‘bone,’ as it is an armoured fish (the plates surrounding the head)
Lived 358 million years ago during the Devonian “Age of Fishes,” and was the largest predator alive at that time. Grew up to 20 feet in length and weighed more than 1 ton, 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.
