Noripterus?

[FF7_Yuffie]

Any pterosaur experts able to ID an old Mongolian tooth? I've been looking into it and believe it could be Noripterus, going by the description of Noripterus been cone-shaped teeth and, the fish-based diet of Noripterus also fits conical teeth.

 

It's an old collection tooth and seller doesn't have the formation, unfortunately, other than it being early cretaceous. I believe it might be from Tsagaantsav Formation which is one of the few formations I could find which fits the early Cretaceous age and has pterosaur remains found. 

 

Now, I personally haven't seen any teeth which resemble this one. The closest is Lyme Regis ichthyosaur, but I don't think Ichthyosaur has been found in Mongolia, I don't think it's a marine formation and there are no striations on the tooth. The base doesn't have a great photo, but it is oval in shape--matching the one pic I could find of Noripterus jaw.

 

I haven't heard anything back from a couple I've emailed it too, except for one paleontologist who didn't recognise it.

 

It's a very small tooth. 12mm in length.

 

If someone is able to take a look, that would be great.

Thanks @Fossildude19

I got this ID'd. The paleontologist who wrote a couple of papers on Mongolian pterosaurs had a look at it for me.
 

Definitely not a pterosaur. More than likely a fish, with a slight possibility of it being an unusual crocodile---but he's saying fish is the most likely. 

 

Figured I'd post the update incase someone else ever looks at this, or something similar gets posted.
