Found by myself in Northwest Missouri
I live in Nodaway County, in Maryville. Its been driving me crazy trying identify it. Byron Noel Miller was my local expert but he passed away. Will be anxiously waiting for a reply
The photos are too blurry to make any positive identification, but it might be a bone. I suggest you contact the Missouri Department of Conservation office in St. Joseph, MO at 816-271-3100 or email NWRegion@mdc.mo.gov for further assistance.
