Pretty sure its a bison (or cow, they can sometimes be hard to tell apart).  Hopefully the degree of mineralization gives you a clue.  There is a book devoted to the topic of comparing Bos to Bison. 

 

A Guide to the Identification of Postcranial Bones of Bos taurus and Bison bison, Darlene McCuaig Balkwill & Stephen L. Cumbaa.  Canadian Museum of Nature, Syllogeus No. 71. Ottawa 1992.

Thanks a ton Mkspsa!  That pretty much confirms my thinking.  It is quite mineralized with only spongy material showing on spots knocked off in river tumbling.  I will check the book you so kindly referenced.  Thanks again!
