"An ancient spiral-shelled squid-like animal related to the modern-day Nautilus."

I had been wanting to find an ammonite (or something similar) ever since I started fossil-hunting. I just collect around my house and since all I usually find is plant material, I didn't expect to find anything marine (let alone an ammonoid). It's a bit rough, but easily my favorite find.
