Harry Pristis Posted August 31, 2007 Share Posted August 31, 2007 Darn, Worthy . . . you're killin' me with those unedited pix. I'm using a dial-up connection and it takes waaay too long to open your images. Do you have editing software that came with your camera or with your scanner? Use the image-editing software (or download shareware at http://www.irfanview.com/ ). You don't have to do anything fancy with the software, but the following things will improve anyone's images. LIGHT IT UP. Use as much ambient light as possible. Halogen bulbs are better for photography than tungsten filament bulbs. The new compact flourescent bulbs come in a "daylight" (6500K) version that you can use in any (non-dimming) fixture. BRIGHTEN AND CONTRAST. BRIGHTEN the image until the fossil appears slightly washed, then adjust the CONTRAST until the fossil is bright and sharp and is a good color-match. Practice this until you get a feel for it. CROP, CROP, CROP. Again, use the image-editing software to crop the image to only what is pertinent. Leave only a narrow margin around the fossil. The more of your kitchen counter-top in the image, the smaller the fossil image will be. REDUCE THE FILE SIZE. The images directly from a camera usually are too large for posting directly to a forum. This forum has a limit of 500 KB. You can constrain the proportions of your image to produce exactly 500 KB (I routinely use 450 KB for my images). I'd like to see your images; please help me. -------Harry Pristis 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...

Uncle Siphuncle Posted September 6, 2007 Share Posted September 6, 2007 The basic criterion I use to discriminate bovine from camelid teeth is the presence of an extra enamel cone one one side as shown in your Teeth2 image. This denotes a bovine tooth. Bison or cow I can't tell you for sure. Here in TX if I see that enamel cone and there is some matrix on the specimen or I pull it out of a bank that is obviously original Pleistocene deposit, I call it bison. Antiquus, occidentalis, latifrons or other species determination is something I'll leave to the more astute among us. If I don't see the enamel cone and it is bigger than a deer tooth I call it camelid, but again I can't tell a Paleolama from a Hemiauchenia tooth. As for the front of the dentition camel canines are pretty easy but I can't comment on incisors. Sorry that's about all I'm worth to you. Grüße, Daniel A.

Harry Pristis Posted September 7, 2007 Share Posted September 7, 2007 The details of camel teeth seem to me to be much different from Bovid teeth. Notice in this image of a camel m2-m3 how simple (relatively) the walls of enamel are compared to Bovids (Bison, above). Notice on the camel occusal surfaces (grinding surfaces where the upper and lower teeth meet) how the lacunae (gaps) between the crests (outer, labial cusps) and crescents (inner cusps) resemble simple, straight "smiles" (or "frowns" in this upside-down presentation). The analogous lacunae in the Bison teeth resemble limp dumbells. The isolated pillar of enamel found on adult Bison teeth and generally not found on cow teeth is called, I believe, a "stylid." You can see it as a "donut" of enamel on the occlusal surface to at least one (left) of the Bison teeth in the image. When I see plications (zig-sag folding) of the enamel in an Artiodactyl tooth, and I'm deciding between "camel" or "cow," I go for cow every time. Plications = Bovid. ------Harry Pristis 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...
Uncle Siphuncle Posted September 7, 2007 Share Posted September 7, 2007 Now we are all learning something. To me camel teeth look much more like deer teeth than bison/cow teeth. That being said, is there an easy way to tell an adult deer tooth from a juvie camel/llama? Grüße, Daniel A. Wöhr aus Südtexas "To the motivated go the spoils."

Harry Pristis Posted September 7, 2007 Share Posted September 7, 2007 I don't think that that's a real problem. Deciduous teeth have their own look -- they are not miniatures of the adult teeth. 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...

Guest BOHUNTER Posted August 14, 2010 Share Posted August 14, 2010 (edited) I didnt find this but I wanted it when I saw it for sure! I dont know if its Bison or Camel. Its just the prettiest brilliant yellow and black youve seen. I think it is actually missing a cusp too... darn! Otherwise nice case filler! Florida Fossil.

Harry Pristis Posted August 15, 2010 Share Posted August 15, 2010 The tooth is complete and is from a sub-adult bison. I agree the single, colorful tooth is a bison m3.

PleistoGuy Posted June 10, 2011 Share Posted June 10, 2011 Are these teeth Camel,Cow or Bison????? All of them belongs to Bison... you can diferentiate them from another selenodonts in the unique possesion of a central pillar or stylid between the lobes, in the 'front' part of the tooth...

Shellseeker Posted June 10, 2011 Share Posted June 10, 2011 This is a great identification thread. Thanks to all who contributed and to PleistoGuy for resurrecting it. I sit here matching the M3 Hemiauchenia I found Tuesday to HarryPristis gorgeous pictures. Once again TFF rules.

Shellseeker Posted November 25, 2014 Share Posted November 25, 2014 (edited) Popping this thread open again because I found a very nice m3 lower that is either Bison or Bos. and therein lies the rub. Peace river is a rough and tumble environment that has a tendency to chip and break up teeth. For a tooth found in medium to heavy gravel, this is in great shape. I have always liked this specific thread because it is very informative in differentiating Camel, Bison, and Cow to the extent that they can be differentiated. Plus I love the yellow coloration of the example Bison tooth above. My first reaction was/is Bison because of the stylid, but then I saw the lighter coloration on parts of the enamel easy to see in the last photo. That may imply a more modern origin. I am flip-flopping and wish to see if someone has a more certain view. Thanks for all replies.

Shellseeker Posted November 26, 2014 Share Posted November 26, 2014 Harry, Thanks for the excellent photos. I realize that I was trolling for a response from you and a couple of other TFF recognized experts in this space. In comparing the teeth identified as Bison lower m3s within this thread, I notice a couple of differences between Bison and other teeth. 1st: all the Bison m3s we see have exactly 1 stylid, which is missing from both Camel and Bos and 2nd: Bison teeth are larger than Bos teeth. Are either or both of those factors differentiating between Bison and Bos? The more I look at this tooth that I found yesterday, the more it looks like a fossil than a modern.

Harry Pristis Posted November 26, 2014 Share Posted November 26, 2014 Bison and Bos both have isolated stylids. In Bison, the stylids are robust. In Bos, the stylids are less robust, tending to break away in teeth that have lost the cementum wrapper. In this well-worn Bos m3, the isolated stylid is represented by a remnant loop of enamel on the occlusal surface. 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...
