Jawbone Of An Asterisk

It’s getting to the point now where nothing I find in the backyard phases me. While transferring to the greenwaste bin all the old rotting kindling that’s been sitting in the backyard wheelbarrow for years now, I look and there on the ground is a partial jawbone (including a few weirdly shaped teeth) about three inches long of some unknown critter. Squirrel? Opossum? Raccoon? Cat? Alligator? IRS agent? Whatever it is I picked it up and dropped it in my pocket and went right back to work.
