Humerus Bone? Please Help Id

[Janeav]

I found this interesting bone fragment in my raised garden bed. I think it must have come in one of the bags of cotton burr compost I applied earlier this Spring. I used 2 different brands of compost -- they came from Georgia, Texas and Oklahoma.

This bone measures 5.5" long, and 2" wide at the joint end.

Proximal end of a large mammal rib. Most likely horse or cow.The head articulates directly between the centra of two adjoining vertebra, and the tubercle to a process which stick out from the side of the vertebra. From the looks of it, possibly one of the 2 or 3 anterior-most ribs. The tubercle is the one which stick out sideways relative to the long axis of the rib.

Rich,

Thank you so much! I wasn't even close with ID.
