Skull and Creepy Crwly Collection Featuring a Turtle Shell

In the long long ago valentine97 kindly sent me this turtle shell along with some other items. The shell has been sitting in this case for a few years now. Perhaps 5 years.
Not sure what sort of turtle this is from. Looks like the kind that live in ponds and lakes. The shell is 4" long and let me say what else I can say about it. It has a top and bottom. The turtle can not climb out of the shell. It is combination of the turtle's skeleton and skin I think. Let me look it up. Bones, skins and keratin. Keratin is like fingernail and claw material.
Along with the turtle shell valentine sent me a leg bone. It is 6" long and looks to be from a sheep or a pig. It's a bit thick for a coyote or racoon. Yep pretty sure it is the uppermost rear leg bone. I remembered I was using a computer and had access to the net. Some people don't seem to realize that as they post a single item and are never seen again.
Almost forgot to mention this is my intro to Halloween post.
