Today we examine the famous bony jawed placoderm fish from the Devonian, Dunkleosteus! We talk about everything from alternate universes, lips, and how you are related to these swimming bear traps! Prepare to learn about the Age of the Fishes and the bizarre fish that inhabited our oceans and could have taken over the Earth! Hope you enjoy!
