It doesn't appear to but cut in half, looks to be fractured in half? I gotta say that sure looks like an egg and yolk. The oblongness (that can't be a word) of it resembles an egg, doesn't it?
I have seen and found very similar objects in fields that used to have horses and other large domestic animals grazing there. They actually are a calcium build up that happens in the gut of the horse or cow...I even work at a zoo and have seen similar round calcuim balls come out of Zebras some almost as large as soft balls but usually tennis ball sized. They are layer after layer of calcium and other minerals this could explain the ball in the center could have been a diet change that made the smaller ball a bit different then the layers that built up around it before it was crapped out.
next time i get kidney stones ill think about those poor zebras
