Amazing huge specimen, Xenophora infundibulum gastropod. This impressive specimen of Xenophora infundibulum, dating back to the Pliocene epoch, stands out for both its remarkable size and its unusual behavior. Belonging to a group of marine snails known as carrier shells, Xenophora species are renowned for their habit of attaching foreign objects — such as small shells, pebbles, and coral fragments — to the outer surface of their own shells as they grow. In this giant 10-centimeter specimen, traces of this behavior can still be seen. The attached materials served various purposes: camouflage, stabilization on soft sea floors, or perhaps even as a form of protection. This habit makes every Xenophora shell a unique mosaic — a collaboration between the organism and its environment. Rare in this size and condition, the fossil preserves not only the physical structure of the shell, but also the story of an animal that actively shaped its own appearance in response to the world around it — a truly remarkable example of prehistoric adaptation and individuality. Coming from an old collection, the site was closed 20 years ago.
