Here's a bone that's incredibly common, but hardly anyone has them, and even I had to look up the proper name for it. I have hundred of skulls in my room, so in theory I should have two of these for every skull, but I think this is the first pair of them I have. And like most animal bones, you will have two of these in your own body !
So this bone is flat, a bit like a bird scapula (shoulderblade). The ones I found are about 8cm long, and at one end look slightly like a rib, with a Y-shaped split. At the other end it is wider and curver, very slightly like a bird humerus, but much flatter. But this one isn't from a bird, but a large mammal. But before I tell you what it is, I'll tell you about how it was found.
