Hey everybody!
I had an opportunity to visit the Holzmaden area (fantastic museum) and split some rocks at Schieferbruch Kromer in Germany. There were plenty of ammonites and I even managed a few neat belemnite pieces I'm very happy about. But one find has me a bit stumped. It appears to be very thin, and I have the feeling it is some part of an ammonite but I have no clue where it would fit in since it isn't very spirally. The caliper scale for reference is in mm and inches (it's about an inch long). The last 2 photos are at an angle to show some of the relief. If you've got any suggestions, I'd be happy to hear them, thanks!
