Anna Posted February 3, 2012 Share Posted February 3, 2012 John found the first two teeth recently in North Sulphur River (Cretaceous) and has asked me to post them here for id. The larger of the two is definintely mineralized--the encrustations on the lingual surfaces are rock hard. The smaller "half" tooth also does not appear to be recent. The third tooth fragment isn't much to look at, and it may not be identifiable, but I was real shocked to find it--in an area recently excavated here in the Kiamichi formation. (Right across the road from our farm.) I though, if anyone has any ideas, it would be kinda cool to know. Normally we only find Texigryphaea sp. and the occasional ammonite until you get closer to the Goodland Limestone exposures around the lake.

Nandomas Posted February 3, 2012 Share Posted February 3, 2012 1 bovidae? 2 canidae? Anyway, they are from the recent upper sediments and not from Creataceous Erosion... will be my epitaph! http://www.paleonature.org/ https://fossilnews.org/ Link to comment Share on other sites More sharing options...
Indy Posted February 3, 2012 Share Posted February 3, 2012 This one reminds me of a "Bison" tooth Check out this web page: Link Flash from the Past (Show Us Your Fossils)MAPS Fossil Show Link to comment Share on other sites More sharing options...
Anna Posted February 3, 2012 Author Share Posted February 3, 2012 I've been thinking bison on the first one...certainly doesn't match up to the juvenile and adult cow skulls we have here.

Indy Posted February 3, 2012 Share Posted February 3, 2012 Matching loose bison teeth with found jaws...might be interesting, however, it isn't a process for identification See the stylid on the side of the tooth. It appears as a little "donut" of enamel at mid-tooth. This stylid is a feature that is used to distinguish loose bison teeth from cow teeth.

Al Dente Posted February 4, 2012 Share Posted February 4, 2012 See the stylid on the side of the tooth. It appears as a little "donut" of enamel at mid-tooth. This stylid is a feature that is used to distinguish loose bison teeth from cow teeth. Web Page: Link I have heard that both modern cattle and bison had stylids on some lower teeth. Here's link to a photo of a cow jaw: http://www.istockpho...ow-jaw-bone.php and here is a different photo: Link to comment Share on other sites More sharing options...
Harry Pristis Posted February 4, 2012 Share Posted February 4, 2012 'Al Dente' is correct . . . cows often do have stylids on their cheek teeth. It is common to see stylids on the deciduous teeth of cows. But, these cow stylids are usually weak and thin-walled when compared to the robust teeth of bison. In fact, the cow stylids often fall away once the cementum of the tooth is gone. I think the tooth in question here is probably a cow m3 with the weak stylid held in place by the residual cementum. Keep in mind that differentiation of isolated teeth of closely-related species may be more art than science. Compare the tooth with this bison tooth: The canid half-tooth is about the right size for a coyote, but domestic dog (or some other dog) is possible. Compare it with these coyote teeth: The third tooth reminds me of a bison or cow P2. Compare it with the P2 in the image above. These images are in my "Teeth & Jaws" album on TFF for future reference. 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...
mikeymig Posted February 4, 2012 Share Posted February 4, 2012 I agree with Nandomus. The first tooth is from a cow and the other is a canid either a coyote or domestic dog and they are recent. Many times I've wondered how much there is to know. led zeppelin Link to comment Share on other sites More sharing options...
Harry Pristis Posted February 5, 2012 Share Posted February 5, 2012 My response about "weak stylids" was not backed up by anything I presented, so I took some time to photograph some cow teeth in order to illustrate the distinction between cow and bison. 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...

Anna Posted February 6, 2012 Author Share Posted February 6, 2012 These images are in my "Teeth & Jaws" album on TFF for future reference. Thank you so much for taking the time to share this information! Asking questions and reading how the experts weigh in teaches us so much! I'd done a considerable bit of searching on my own trying to come up with an answer, but nothing appeared nearly as clear and concise as what you've presented!
