It's not my tooth, pinky swear!

My friend found this tooth in Lake Wedington in northwest Arkansas.

She's asked biologists, veterinarians, doctors, geologists, gas station clerks and everyone else she's met for the last 20 years but so far no one has known.

Do you have any idea what animal this tooth might have come from and - especially - the animal's history? Why is it so obscure? Why did it (or its tooth) turn up where it did?

Best answer: Not a local, not a proper biologist, just an ecologist with little actual experience (and bugger-all in vertebrates), but: looks herbivorous, looks fishy, found this page when I googled 'herbivorous fish dentition', which has this image that looks remarkably similar.

So … Grass Carp or similar?

Best answer: Nthing that is a herbivore tooth and I am SO excited I know this!!!

I know for a FACT because I am a long time member that you can email the Natural History Museum of LA with pics (especially a pic with a penny for scale) to get a definitive answer. It may be a fossil, or more recent. Memail if you want help because I have friends that work there and may be able to expedite your inquiry. In general, you can email members@NHM.org to get an answer. I don't think they'll care you are not a member, but I'll submit the pic and follow up in person there's an issue.

They are super science hereos and are happy to dig in (pun intended) but I'm available if you need a go between. Cheers!

I'm not an osteologist, just an archaeologist, but my hunch is fishy too.

Have you tried a Natural History Museum? Twitter has a lot of museums and curators, if you're on there, try tagging a few with the pictures.

There's also many beachcombing and beach finds groups on Facebook, which often have a few experts around who help with IDs.

Best answer: Yep, pharyngeal teeth of a grass carp.

"comb-like throat-teeth" in their genus name is pure nightmare fuel.

Response by poster: Thanks for knowing this! She actually asked on r*ddit and got the answer after a few days. I bet her that AskMe could answer faster. 26 minutes FTW!!! ❤️
