Ptychodus Mammillaris

this compares more favorably to P. latissimus IMO. Much rarer!

You are correct @Jared C

It can be difficult for people to see the differences between species. And, there are some Ptychodus teeth that are somewhat "cross" species (they look like they are half one and half the other). But when you start knowing what to look for, it gets easier to make an educated guess. But as Shawn would always say, it's better to have a dentition or associated teeth. Yet, that is such a rare occurrence.

Beautiful tooth and I think Jared is right on the money with P. latissimus
