Unusual Marine Mammal Tooth

Hello TFF! Just found this unusual looking tooth in VA on the York River, and I’m assuming the Yorktown formation? It’s about an inch in length. My assumption is that it’s some kind of dolphin or porpoise tooth with some extra root or jaw bone attached? Let me know what you think!

Where in VA? Size?  Any idea what formation it is from?

 

 

Cropped and brightened:

Thank you for the crop! It was on the York River. So I’m assuming Yorktown formation? It is about an inch long. I found some sand tigers and bull shark teeth on the same beach.

Looks like it could be a saw shark rostrum tooth.

Ah that’s pretty interesting if that’s the case. It was found along the York River.

This is a dolphin tooth - Ninoziphius platyrostris to be exact. It's one of the few odontocete teeth that can be identified to species. It has a bulbous hollow root and a relatively thick crown, and has been found in the Yorktown Formation at Lee Creek and in Virginia.

Sounds good to me, thank you!
