lol. i guess you guys don't watch discovery much, but yes the Dunkleosteus pic was from a show about dinosaurs talking about what it would be like for a man in the ocean back then or something like that.
I showed the pic cause i always thought since i was a kid that the Dunleosteus was the scariest thing ever to exist, even if it wasnt the most dangerous thing to ever live. I'm always amazed at how such creatures ever existed, i bet a guy with a gun even would not live 5 minutes anywhere back then
