From the album: Holzmaden
A kinda interesting combination out of an ammonite, a belemnite and a partial Ichtyosaur rib. It wasn't very difficult to prep but all in all it took about 3 hours. The belemnite is about 10 cm long and the partial rib is about 11 cm long. I found this one last year in the quarry Kromer near Holzmaden.
