Ice age tibia?

[Jwlipps]

I found this tibia(my girlfriend is an emergency vet and  identified it as such, with a small amount of research I confirmed) half buried in the sand on a private beach adjacent to dash point in Washington on the shore of the southern end of Puget sound. My apologies I could not find a ruler with metric measurements. My main question is it seems small to be from a large mammal, but it does appear to be in great shape, so perhaps from a young animal. I’m I correct in assuming it’s an ice age mammal. I know there are tons of glacial deposits.

Corroded and missing its epiphysis, compare with cow:

Yes this tibia look bovid like to me.  Maybe some species of auroch or bison.

Cool! That’s kind of what I was leaning toward. Thanks!

I think it's too small for bison.  Compare with these:
