Natural Bivalve Fossils.
They are the ancestors of the current clams and seashells such as coquinas, clams, scallops... They used to live in the waters near the coasts.
Only the valves (shells) fossilize, which constitute the exoskeleton, composed mainly of calcite and aragonite, the latter being the one that gives the current shells an opalescent appearance, although during fossilization it is transformed into calcite.
The fossil includes a label with the name, period and provenance and is attached to a 4 cm square cardboard box.
*The price is per unit (a single cardboard box of the four shown in the photo)
Since the samples are natural, you will receive a piece similar to the one in the photograph. The fossils come in cardboard boxes and are glued to a porex base with hot silicone; these can be removed using ethyl alcohol without damaging the fossil. The size is approximate.
