My husband and I are building our first home and much to our surprise, we found several bones in our backyard. I'm praying it's from an animal... All of the bones are exactly 1/4" thick and appear to be cut cleanly by a machine of some sort. I placed a US quarter for scale. Please help identify!
These are the bodies of vertebrae which, as you say, have been cleanly cut by a machine. The animal they came from was young as indicated by the inverted V shaped line on photo 3, this is a growth plate which disappears in adult animals. The shape of the bone in photo 1 and 3 indicates that they are from the lumbar (lower back) region of the spine. The size is consistent with sheep. Putting it all together they are the remains of three double loin chops.
