Help with Tooth ID

[PODIGGER]

Found this small tooth last week while hunting the Peace River.  Almost missed it in the sieve and initially thought it was just a chip of something.  On getting it home and giving a closer look I became convinced it is a tooth.  Maybe an incisor.  After a lot of searching on line the closest I could come up with is horse incisor.  Only I think it is way too small for that.  The chewing surface appears more jagged and uneven then I would expect from a herbivore.  The groove along the length of the tooth and its curvature are similar to what I have found on horse incisors.

 

Measurements - Inches = 3/4"L x 3/8"W x 1/4"H

                            CM =.      20mm L x 10mm W x 6mm H

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

@Shellseeker, Jack - I would appreciate your input knowing how much time and effort you put into finding the small 3-toed horse fossils.

 

Thanks,

Jim,

I have looked at many angles... and yet I am not seeing enough detail. Interested in this photo...

Is the outside enamel ??  What is the inner core ? I need to increase magnification 5x.... more pixels in the photos...

 

At first I thought Mammoth root,  it can have grooves like that.... and a couple of layers with hollow core...

But then what looks to be enamel at the broken end...

So , I grabbed these photos from last year... Yes, I would agree that Equals incisors  can have a groove...

Jack,

Thanks for the response.  I do believe it is enamel on the outside.  I have several small Mammoth roots, a couple that Dr Hulbert Id'd for me.  The exterior of all those have the roughness you find on the exterior of the plates.  Your second photo makes me lean even more toward incisor. This specimen looks like enamel and has a very smooth finish.  I'll try and get some improved photos.  The brown on the exterior of this one is staining.  

 

Is the size just really too small for any horse?

@Shellseeker 

A couple of more photos.  Brightened and zoomed to 5x.  I also included a known mammoth root for contrast.  Smallest one I have and one that was confirmed by Dr Hulbert.

I do have a couple of 3toed incisors,  I think more worn than yours,  but both are approximately the same size.

 

Having tried to add these,  I realize that you have very detailed photos of small items

It's definitely not a mammoth tooth root. I wonder if it's a juvenille equus incisor root? my 3-toed incisor is quite similar to yours, @Shellseeker, but less worn. Looks quite different from the one that @PODIGGER has, though.

Thanks Jack and Meganeura.  Maybe we can get @Harry Pristis to offer his opinion?

I think it's a fragment of a horse incisor, species indeterminate.

Thanks to Harry and all those who responded.
