FOUND: petrified leg bone. Buffalo?

[Youngbuck]

My dad found this in a stream while fishing. It is obviously petrified because it feels like a big rock. Any idea how old or from what?

Here's a paper that tells how to distinguish between bison and domestic cow bones:

A guide to the identification of post-cranial bones of Bos taurus and Bison bison
by Marlene McCuaig Balkwill and Stephen L. Cumbaa, 1992
Canadian Museum of Nature, Syllogeus, no. 71.

It is available from the Canadian Museum of Nature (web site: www.nature.ca).

Good luck

Has anyone figured out how old this bone is or what it is from?
