An old Potomac find

[automech]

I recently posted in the Fossil trip section about an outing last June. And the strange/new finds made me think of a tooth I found well over 12 years ago in the predawn morning of a cold December day. The temperature was in the low 30’s F. The only light I had was a headlamp.  I found it sitting on the rocks at the break of the surf . My biggest MD tooth to date.

As you can see, it’s pretty beat up. But, if anyone can take a guess that would be great.

It's pretty worn...I can't tell if it has a bourlette or not.

I’m thinking I see the remains of a bourlette. But the rest of the shape doesn’t fit so I could easily be seeing things

@Randyw, same here.

So what would you guess this is .... a mako?

I'm not comfortable making a guess, but someone else may be.
