Bones

Adam put in our new security screen door Tuesday night. Being that nothing in our house is standard or built porperly, we needed to modify our threshold. Adam removed some concrete from under the metal plate and we found bones embedded in the underside of the concrete! I don't know what kind of bones they are. All I know is it is really weird!! Why would someone put bones under their threshold? I shutter to think if there are more hidden under/in our house. Oh how I wish we had a "normal" house. Bones aside, the door frame is so crooked we had to make a decision. We could install it to match the crooked door or install straight. We opted for straight and now it is really noticeable how messed up the door frame is. I guess levels were scarce when the guy built this house as pretty much nothing is straight in this house. So, what should I do with the bones? They're probably animal or from a steak or something like that but I wonder if I should call someone. I'll save them for now. Here's a pic of our screen door and a pic of the bones:
