pterosaur tooth

[gturner333]

I obtained the following tooth today and was told that it was a pterosaur, possibly an Ornithocheirus sp. It was found in the Britton formation in Mansfield, TX. Could someone confirm or correctly identify this tooth for me?

 

The scale hash marks are 1mm.

 

Thanks for any help.

Ornithocheirus is only known from extremely fragmentary material from the up, and the two worn teeth on it (and the teeth of others related to it) look different from this, I think it’s safe to rule that out. It does look pterosaur to me but I know little about them, only what I have read.

I agree that this looks like Pterosaur. It seems fairly similar to the Siroccopteryx teeth found in the Kem Kem beds.

Let me add that Ornithocheirus cuvieri is synonymous with Pterodactylus cuvieri which has gone through several genus changes and material found in this fauna was called that.  So that is why the Ornithocheirus ID was probably attached to your specimen.   

 

In 2015 with new discoveries a new species was described, Cimoliopterus dunni from the Britton Formation on the north-central Texas, United States.   Both O. cuvieri and P. cuvieri are synonymous with this new species.  There were no teeth recovered with the holotype so we do know what the teeth looked like.  Holotype included an upper and lower jaw.

Thanks for the confirmation. My research had uncovered the Cimoliopterus  in the Britton formation, but i hadn't connected them together.
