A Monster Tooth From the Paleozoic

Excellent Ben never heard of this shark before.

[@elasmocast]

I’m glad you enjoyed the video! It’s a lot less-well known than many other sharks and shark relatives, likely due to scarcity of their fossils.

"7:30" peripristis. I've got a couple specimens from that species they are tiny compared to that one but I know I do because I've had a vertebrate paleontologist look at one and he ID it as peripristis semicircularis that's crazy. found in Texas

Very nice! Yeah, Peripristis get dwarfed by the size of Megactenopetalus. Peripristis teeth can be hard to come by, especially in good condition as the teeth are so thin and fragile.

Megalodon is over rated anyway

As much as I love megalodon, I do think that there are many more interesting extinct chondrichthyans!
