What type of bone is this?

Found this bone at the river. Wondering what type of animal it was from?

You have a bovid (cow, bison) metacarpal.

Thanks Harry for your intellect!!! Is there any way to determine an approximate age?

No, not really. You can put some 'not earlier than' dates to it. Cow, say 500 years. Bison, say no earlier than the Yarmouthian Interglacial Period.
