Shark Or Fish Teeth?

Recommended Posts

They appear to be the cutting (incisor) teeth from a pycnodont-like fish called Hadrodus. Not 100% sure, but that's the conclusion thus far.

Thanks Roz for giving me contact info for Mike.

You are welcome, Lyla.. If it is Hadrodus, I am thinking a new one then.

At what point does it become pretty sure that it's a new one and things

can proceed from there? Does anyone know? I am not sure how

that would work in this case..

Welcome to the forum!

That's a good question- Mike is out of Kansas and was comparing to finds from Kansas. I'm in an area where there's not a lot of studying going on other than size comparison (correct me if I'm wrong folks). Dallas has their museums, but I'm not sure they would have studies from my area. Kansas has some of the same formations etc. so it's comparable.

I'd doubt Hadrodus because, as I understand it, Hadrodus is known from its brachial rather than oral teeth and the ones in question are definitely oral. Since Hadrodus is a pycnodont and the posted teeth also seem to be, the oral teeth would likely look pretty similar - it's just that I don't think Hadrodus oral teeth have definitely been described.

Try contacting Jürgen Kriwet (Vienna, Austria) - he's a pycnodont expert: http://www.fish-rese...t_Lab/Home.html

Also, try Kenshu Shimada (Chicago, IL) - he has worked on fossil sharks of the Mancos Shale and has written up pycnodont teeth like these: http://csh.depaul.ed...es/shimada.aspx

Carl:

Thanks for the info- I have emailed them both to see if they may have any ideas.

Well I'm still trying to figure out what these teeth belong to. The gentleman from Austria doesn't think they are pycnodont teeth either and does not have a clue to date. I have not heard back from the gentleman from IL. Anyone else have any suggestions as to who I might contact?

You might look for Jean-Pierre Biddle, a French paleontologist with an interest in Albian-age fossils.

I can't find any contact info on Jean-Pierre Biddle.

Jean-Pierre had his own forum on which he put his works, but it is not on-line any more for several years. I met him once at least 5 years ago, and I don't know what he became since.

What an amazing find! Please keep posting as you learn more. I have never seen anything like it.

Well so far everyone I have contacted has no clue (or has not responded). Anyone else have any contacts?

Lyla,

Have you tried John G. Maiseyat the AMNH?

I believe Roz and Bobwill had luck contacting him.

Hope this is helpful.

I just realized that your teeth look kind of like the Pharyngeal teeth I have from a grass carp. I don't know how long pharyngeal teeth have been around, but I think most of the minnow family have them.

(By "your teeth" I mean the teeth you found :P )

Hey I have some of those too :)post-4072-0-51102500-1345594359_thumb.jpg

Kind of similar but not so similar if that makes sense as there's really no ridges on the ones I found. John Maisey didn't have a clue. I will try to contact Dr. Schultze.

I have some, also. Gave them to my son, though.

That seemed plausible to me, too. It actually crossed my mind before, but I wasn't confident enough to post it.

Dr. Schultze didn't know either and he shared with another who didn't have a clue. They suggested perhaps Multituberculates but didn't like the layout of the teeth.

Does anyone have contact for Ann Weil in Oklahoma? I found her contact info...

I would have to strongly disagree with multituberculate.

I agree...Ann said they were not. She again mentioned pycnodont. I have sent the pictures to a ton of individuals. Pycnodont is the one that people keep mentioning.

If no one knows what it is, it must be a rudist!
