Fossil Tooth and 3 bone fragments

[DesertSparky]

Hello,

I recently found a fossil tooth and 3 bone fragments that fit together.  These were found about 8-10 miles from Fossil Lake, OR.  This area is the richest fossil location for Holocene fossils short of La Brea tar pits.  There have been horses, camels, bison, rhinos, giant sloth, and giant beaver among some of  the fossils animals found there.  I suspect the tooth may be a bison tooth, but I am no expert and that is why I would like to get more information on it.  The tooth is approximately 5.5 cm X 2.5 cm (2.25 in. x 1 in.).  The bone fragments fitted together are about the same.  A broken humerus was found in the same location.  Unfortunately, I don't currently have it and do not have a picture of it to provide. 

 

Any information that anyone can provide is appreciated.

Since both pieces are heavily fragmented, i'm in doubt an ID beyond "Tooth" and "Fragment of a bone" is possible.

The tooth is from a mammal, like horse or something like that.

Thank you.  The bone fragments I didn't hold out any hope of IDing, but the tooth I was hoping.  When I get the opportunity, I will get pictures of a broken humerus found at the same location although I am not sure when that will be.  I appreciate the info.
