Horse molar

Yesterday,  not finding much beyond small teeth (Lemon, Dusky, Tiger) .... and in the last sieve before I pack up this tooth , just barely erupted... Those are some "really" small measurements of the length and width...

Tooth is a left M3. The wear and damage does not allow me to see if it has an isolated or connected protocone. Shape of fossettes suggests Neohipparion eurystyle but that is a possibility, not a firm ID.

Sent an email to Richard Hulbert.  He responded quickly. 

I am pleased that there is enough for a tentative identification. Adding @fossillarry for possible comments.

If N. eurystyle,  It would only be the 2nd tooth of this type I have found at the site. Most teeth are N. aztecus,  with a single N. westoni.

Trying to confirm this find as a Neohipparion eurystyle left M3 is not simple..  Here is an example of Neohipparion eurystyle left vp_uf-tro01608occ.thumb.jpg.02140b1bac35cc12f90e99a07026013a.jpgM3 from the UF Paleontology Database:

 

Followed by one of @Harry Pristis  excellent pictures of Neohipparion eurystyle M3

This last photo leads me to believe my find has been squeezed/ crushed under tremendous pressure. That pressure has slid the protocone (which should be centered) to the right.  Curious.  Does any one understand the process that could exert such pressure.    Thanks for looking.  Jack

This does not look like tremendous pressure was applied, the protocone in Harrys pic is off centre to the left, yours is off centre to the right so opposite side of the jaw.

These teeth are not plastic (sensu lato) -- no sliding protocones.

 

Jack, can you highlight the enamel pattern on the occlusal surface, and re-photograph it.  You might rub the high points with a number 2 or 3 pencil lead to make the enamel more discernible.

Thanks for the replies.  I was reaching for any explanation for the small size (17.5 x 13) and damage.  As with most of these small teeth, they look almost pristine coming out of the water.

 

Interesting technique on the pencil.  Fortunately, I could find a set of drawing pencils in my wife's art supplies. Hard to get into the valleys..
