Fossil ID: Bison or Cow?

[Praefectus]

Hello. Is this tooth a cow or a bison tooth? Let me know if you need any more pictures. Thanks.

Take a shot directly down on the chewing surface.

Not sure you can tell by only the teeth.

Cow I think. I don't see any stylid to indicate its being from a bison.

I was under the impression, at least from collecting teeth in Florida, bison AND bovine had stylids. And camels/llamas did not. Am I confused???

I agree. This one appears to have a stylid anyway.

There are a few discussions on here, but this is the one I seem to choose first.

bison/cow

I guess it is more complicated than I thought, but I still say this looks more like cow.

That post kept referring on and on to link after link which eventually got me to this :

 

"The presence of this isolated stylid distinguishes bison and
cow molars from camel teeth. The overall larger size of the teeth and the more
robust enamel, including that of the stylid, are features that are used to
distinguish loose bison teeth from cow teeth."

Praefectus,

You seem to be showing a tooth in excess of 2 inches (51 mm) . Bison teeth are more robust and larger than the equivalent tooth in a cow.

What is the chewing surface length of your tooth?

[Praefectus]

Is the chewing surface length the measurement across the top? 

 

It is 1.75 inches (4.4 cm).
