Check out Bizarre Beasts!    • The Bizarre Beast with Clear Blood  

At more than 2 meters long, Aegirocassis was not only the biggest radiodont ever, but it also may have been the biggest animal in the Early Ordovician. This bizarre marine giant may have only been possible, thanks to a major revolution among some of the tiniest organisms in the world.

Thanks to Franz Anthony (http://franzanth.com) and Ceri Thomas (https://nixillustration.com/) for their excellent radiodont illustrations featured in this episode!

And special thanks to Peter Van Roy for providing us with those excellent Aegirocassis fossils!
