Diplocaulus is from the same family as Diploceraspis, apparently both of got extinct millions of years ago, I don't know where the pic was taken or what's the deal with it...I just wanna share...I am from a giving nature...()
I think this one is known as Hammerhead Salamander, but it looks practically the same as the "Diplos" I found on wiki... feel free to research as much as you want, I am tired right now...gotta go...
