I want to show you some molluscas from the "Arietenkalk" formation. (Jurassic)
I found them on a this location: http://english.fossiel.net/sites/fossil_site.php?plaats=392
Shadefully there werent any good construction sites, so i cant find big ammonites (i dont have the tools either).
Because of that i concentrated to find some nice bivalves ....
I think i found three species, but i am not sure with the ID.
First 2 molluscas, maybe Plagiostoma:
5 cm long and a bit damaged:
4 cm long:
