Regrettably and due to missing, proper storage and exposition facilities, the fossil collection of CID Institute Museum has been mixed up several times during the past decades, with the consequence, that the original finding site is not more exactly registered for all specimens or some site-related collections contain objects that seem to belong to other search locations.
This is specially the case for the following presented specimen collection. Their procedence could be from Southern France (Ardeche-Gardon Region, Luberon, Languedoc-Roussillon), Spain (Costa Brava Tarragona Region, Andalucia Malaga Region, Galicia Ponteverdra Region), Colombia or Nicaragua.
The objects contain fossil marine shells similar to recent Crepidula (Common Slipper Snail MOLLUSCA : GASTROPODA : CALYPTRAEIDAE) or fossil Gryphaea (Devils Toenails) species. The fossils let visually dinstinguish the mineralized calcareous housing shell and the body cavity filled with a petrified (fossilized) sediment ("stone-kernel").
