Stingray teeth

[Nipponites]

Hello,

I have these stingray teeth that I haven't been able to identify.

I only know that they are from Khouribga phosphates (45-70mya).

Any ideas?

 

 

 

Thanks in advance!

Not "stingray" in the way I know them--dasyatid teeth are individual tiny teeth with a pair of roots. These look to be myliobatid (eagle ray) teeth. If they were Miocene-Plio/Pleistocene, I'd call some of these Aetobatus because of the curve that seems to be there.

For that age I'd consider them some form of myliobatid tooth.

Hopefully, someone with more experience in the formation will be along with more authoritative info.

 

 

Cheers.

Thank you very much!

I had no idea about rays, will look at myliobatids from there.
