Striated both lingually and labially!

[readinghiker]

Hello all.  Back again with another unknown species from the Cabezon Coniacian fauna.  You people were a great help in identifying the 

Cretoxyrhina  tooth that I posted a couple of days ago, hopefully, you can help with this.  By far, the most common striated tooth found

in this fauna is Scapanorhynchus, of which I have literally thousands of teeth.  There are a few that are looking like Leptostyrax that we are

researching.  And then there is this one.  Not only does it have striations on the lingual face, as one would imagine, but it also has striations on

the labial face.  Any ideas?  After you reply, I can post another picture, since I can only upload one at a time!

 

Thanks!

Randy

I'm not sure what this tooth is but clearer photos would help someone who does know, you can either change image size to add more than 1 or you could just reply right away you don't need to wait for someone else to respond
