The Exogyra is an extinct genus of oysters, they are known as foam oysters or honeycomb oysters.
This bivalve, with a closed shell, has an oval left valve, ornamented by scales and ribs, with this valve they were fixed to the surface substrate, while its right valve was smaller and flattened and served as a cover.
Individuals of the genus Exogyra lived on hard substrata in warm seas (mainly in Europe) at shallow depths.
The fossil includes a label with the name, period and provenance and is attached to a 4 cm square cardboard box.

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.
