Late in the Devonian, some 382 to 358 million years ago, around the same time when the first vertebrates were crawling their way onto land, a massive predator called the ocean it’s home. The size of a modern day Orca, Dunkleosteus was a fish unlike any alive today. It belonged to a group of fish called placoderms, all of which possessed heavily armored bodies, to combat this Dunkleosteus had a brutal adaptation, instead of teeth, the plate like parts of it’s armored skull extended down into cleaver like blades that self-sharpened every time it shut it’s mouth.
