This is a kinda funny combination out of a fish bone and a very rare pterosaur bone. The fish bone is the bigger one (5 cm long) and is lying on the top of the pterosaur bone. The piece comes from the quarry Kromer near Holzmaden (Lower Jurassic).
As these are marine deposits you can imagine how rare the pterosaur bone is
Some very bad detailed pictures: (sorry for the bad quality but my camera is not good enough)
