diginupbones Posted June 21, 2019 Share Posted June 21, 2019 This one looks different from the rest of my collection. I’m hoping it’s something unusual like the last one you identified for me. Thanks TOPBOTTOMSIDE Link to comment Share on other sites More sharing options...
garyc Posted June 21, 2019 Share Posted June 21, 2019 Looks like a horse tooth from a very old animal. 1 Link to comment Share on other sites More sharing options...
Harry Pristis Posted June 21, 2019 Share Posted June 21, 2019 It may be a horse tooth, but I'm not sure without seeing the occlusal surface. Diginupbones is confused about "top" and "bottom." The occlusal surface (the top) is covered with matrix, it appears. The roots (the bottom) are sheared away, leaving openings to the pulp cavity. If the matrix covering the occlusal surface is cemented sand, give it a bath in vinegar to weaken the calcite (probable) binder. Then brush or pick away the remaining debris. The vinegar is unlikely to hurt the tooth itself. 2 http://pristis.wix.com/the-demijohn-page What seest thou else In the dark backward and abysm of time? ---Shakespeare, The Tempest Link to comment Share on other sites More sharing options...
diginupbones Posted June 21, 2019 Author Share Posted June 21, 2019 Will do! I will post up some fresh pics a little later. Thanks Link to comment Share on other sites More sharing options...
diginupbones Posted June 21, 2019 Author Share Posted June 21, 2019 Thanks for the top and bottom lesson and the tip on the vinegar! I’m learning something new with every post. Here’s a nice clear pic. 3 Link to comment Share on other sites More sharing options...
Harry Pristis Posted June 21, 2019 Share Posted June 21, 2019 It's a horse alright, but not equus. It is a tridactyl (3-toed) horse. 5 http://pristis.wix.com/the-demijohn-page What seest thou else In the dark backward and abysm of time? ---Shakespeare, The Tempest Link to comment Share on other sites More sharing options...
diginupbones Posted June 21, 2019 Author Share Posted June 21, 2019 You just made my day! I’ve been reading up on the evolution of horses in Nebraska and the three toed horse really fascinated me. I had no idea I would ever find a tooth from one! Thanks! You guys are awesome 1 Link to comment Share on other sites More sharing options...
garyc Posted June 23, 2019 Share Posted June 23, 2019 Wow! That cleaned up nicely. I think @Shellseeker is getting pretty good at three toed horse id’s. Let’s see if he’ll take a stab at this one. Link to comment Share on other sites More sharing options...

My expertise is mostly Florida focused but many of these horses spread across the US, especially Nebraska. @diginupbonesYour tooth is longer at 30mm than I find normal in Florida (usually closer to 20-24 mm). If your tooth was found in Florida, it would be called Cormohipparion!!! Good google search for Cormohipparion and Nebraska. You might find this TFF thread interesting : Look for Cormohipparion Plicatile at the end.

fossillarry Posted June 28, 2019 Share Posted June 28, 2019 Deciduous (baby) horse tooth. could be Nannippus aztecus or Cormohipparion emslei based on size. Link to comment Share on other sites More sharing options...

Larry, I had discounted N aztecus as an option based on size. I have 3-4 upper aztecus teeth that have lengths in the range of 15- 20 mm. http://www.thefossilforum.com/index.php?/gallery/image/46496-n_aztecus_p34jpg/ @diginupbones tooth seems to measure at 30 mm. C emsiei is definitely a leading contender.
