Mystery Texas Mammal Tooth


Recommended Posts

GPayton

I've had this tooth for about a year now after I found it on the Brazos River near Houston last summer. It's definitely fossilized and has the exact same texture and weight to it that all of the other fossils I've found in roughly the same area do. As far as I can tell the whole tooth is still there, but unfortunately the occlusal surface that makes identification the easiest is almost completely worn down, I'm assuming by the animal's age at the time it died. 

I've tried matching the shape of the top of the tooth with others I've found pictures of, but the issue is the pea-shaped "pinched in the middle" look is very common amongst many mammal species - tapir, deer, sloth, etc. The other thing throwing me off is the single root it appears to possess. 

If someone could help me with identification or point me in the right direction I'd be very grateful!

What is the Length of the chewing surface?

 

To me it looks like pre_Equus horse

The chewing surface is almost exactly 2 centimeters across @Shellseeker. And I definitely agree with the pre-Equus ID, although I'm surprised that it wasn't the first thing that popped into my head considering the small collection of other teeth of the same variety I've found nearby. Hopefully the measurement is enough for you to confirm your suspicions - thanks again for the help!

The 2 in my photo are 22.65 mm and 18.75 mm. As I responded, I wondered if I just had small horses on my mind. i.e Whatever you showed me === small horse. :rolleyes:.

It might be Cormohipparrion, but as you say, too worn to identify.
