Aloha, here is the best of my collection. Since I moved together with my girlfriend, only the small and nice samples are on display, one showcase out of three. Looking forward to the day when we will have some more space. So it is a crowded mix of fossils, minerals, recent beachfinds and mosty selfmade or altered skeleton models. Sadly, only a small percentage of my fossils is selffound, although nearly all of the beach stuff is. There is the "poultry showcase", dedicated to Birds and pterosaurs (Parrot skull is a replica of course, as is the Pterosaur plate regrettabl
