WA state shark tooth

[Fossilis Willis]

Hey gang. This is my first looking for an ID, hopefully I'm going about it the right way. I found this gorgeous little tooth a couple weeks ago in big chunk of matrix I brought home from an exposure I believe is miocene Lincoln Creek Formation. It is my first found shark tooth, and I am super excited about it. From what I can tell, shark teeth are fairly uncommon in Washington, and any ideas on species would be much appreciated. Sorry for poor image quality,  photography is on the long list of things I need to improve upon.

Alright, I tried (and tried and tried) to take a clearer photo without a lot of success. This was the best I could come up with. Thanks for having a look.

If this is Miocene, it could be a lower anterior Carcharodon hastalis. I thought the Lincoln Creek Formation was Eocene or Oligocene?

Thanks for the help. It's my understanding that the LCF is late Eocene to early Miocene.

It looks like Hastalis to me as well.

I appreciate the help. Unfortunately teeth are few and far between in these parts so I am quite ignorant when it comes to identification.

For what it's worth, this could pretty easily by an Oligocene Isurus tooth - the taxonomy is a bit muddled but when you get into the Oligocene the oxyrhinchus and "narrow form" hastalis teeth sort of converge into the same morphotype and are difficult to tell apart (if indeed actually separate).

Honestly I'm really into collecting exotic shark teeth, and I've never even heard of a tooth from Washington haha. Congrats on your find!

Thanks. I was in absolute disbelief when I realized what I had found.

I had a feeling identification might get a bit sticky, especially since it's missing a bit of the root. Not to mention the fact that my photography skills leave much to be desired. Thanks for the input!
