6 months ago, hunting with a partner who found this tooth that I initially identified as Rhino. See those crossing lines in the thin enamel of the 1st two photos. I had seen that in other Rhino tooth enamel found in this location. Before asking TFF for an Id on any fossil, I search TFF for similar fossils and found a thread where @Harry Pristis identified a very similar tooth as Cow or Bison. I never put this one up for identification on TFF. Today, I was commenting on this FossilID thread posted by @Done Drillin http://www.thefossilforum.com/index.php?/topic/124645-peace-river-id-help/&tab=comments#comment-1358464 and noted that Harry Identified a very similar tooth once again as Cow or Bison.. The last find appears to be a bovid p3 . . . the enamel striations suggest bison. I have studied the enamel and see the striations on the outside of the enamel of Done Drillin's tooth, and not on the domestic cow example above. Here is an example of lines in the enamel ... So, now I am wondering on the identification of this tooth. I have thought for 6 months that it is a Bison premolar. Do Bison and Rhino have similar lines within the enamel of their teeth? and are those lines missing in modern cow?

Weather was cold and windy yesterday, but sunny and calmer down in southeast Texas. Sandy gravel matrix. I always hate to get my hopes up too early in the game, but I think I may have found my first 3 toed horse tooth. I looked at Hulbert's Fossil Vertebrates of Florida book. Photograph D on pg. 292 is a right m1 or m2 from nannippus aztecus. It appears pretty similar, but I'm not sure about size. Nannippus Aztecus would have been in Texas from late Miocene to Pliocene, so region would fit. And I think @garyc has found a nannippus on the Brazos before in this general region. My husband and I weren't able to take very good pictures of measurements of the occlusal surface without sacrificing accuracy. Gave up on trying to photograph it with the ruler and got better results. MSCH, from root to parastyle: 36mm APL, length of crown enamel: 18 mm TRW, width of crown from mesostyle to posterior protocone: 16mm. @Shellseeker @Harry Pristis @garyc

Hey everyone! So I have this tooth laying around for a while, not exactly knowing what it is. Have been struggling a lot with determinating it, so I hope someone can help me out It's from miocene/pliocene layers and its length is about half an inch. This is the tooth in question (I'm sorry for the bad quality, had a hard time photographing it ): I saw this picture: Source: http://www.fossilguy.com/gallery/vert/fish-shark/hemipristis/hemipristis.htm Could this be a match?
