Cow Or Bison Tooth

Found this tooth in a dry stream bed in wyoming near sundance and the black hill during a mapping project at field camp.

It has some mass to it, feels unlike a modern tooth

enjoy

my understanding is that the presence of the stylid differentiates bovid from camelid, and that subtleties between stylids in bos from bison can be used to distinguish between the 2, but confidence level for most of us in doing this isnt very high.

Is it not the fact that the stylid is isolated which enables it to be determined as bison? The stylid is a characteristically bovid feature and – if both present and isolated (on cheek teeth) – that distinguishes bison from bos? On old and weathered bison teeth, the attachment of the stylid can be sufficiently weakened that if falls away completely and that’s what creates much of the uncertainty for isolated teeth with no context.

Actually, the character is so variable it can not be reliably used to differentiate Bison from Bos.

that's why i chuck anything that doesn't definitely scream bison to me due to attached matrix, size, color, and/or density...no point in filling my house with cow parts.

Nice find Nathan! For someone who collects invert fossils (primarily) finding a tooth like this (cow or bison) can be thrilling. I'm certain I wouldn't have chucked it back down on the ground. Just like you didn't. ;)

Apologies if that sounded jerky above....at times I run into lots of bone of questionable age and have to make some decisions on the spot.

I too agree! Posted and ID question about a tooth and it turned out to be a pig's tooth. Still cool to me though, as there haven't been any in the area it was found for over 100 years. The archeologist part of me kept it. :)

Heck I wouldn't blame ya. Choosing between lugging a good "known" find home or a "questionable" one... back on the ground goes the questionable find for the next person to scratch their head over! :)

I tend to keep everything I find....much to my wife's dismay. Then when I start running out of space on shelves either inside the man cave or the garage, I start thinning things out into the garden. Sometimes I bring bones home that seem old at first. Then they dry and are obviously not very mineralized. Those end up in the trash. But for some reason I just can't seem to get rid of any teeth, even when I'm sure they're cow. I probably have some weird 'philia' disorder.

I've got a platter full of modern bones that I've not been able to toss too, and I've also got buckets of rocks, broken shells, and tiny unidentifiable fossil scraps. Hard to give any of that material up after spending the calories to pull it out of the ground.
