Designation

Fossilized shell imprint in matrix

Description

This specimen consists of a sedimentary rock matrix, likely a calcarenite or fossiliferous limestone, containing numerous imprints and fragments of marine organisms. The most prominent feature is a well-defined external mold of a bivalve shell showing distinct, regular radial ribbing characteristic of the Pectinidae family (scallops). The matrix is light beige to grayish-tan in color, with a granular and porous texture containing smaller clasts and micro-fossils. Other smaller, less distinct molds of shells and possibly tiny gastropods are scattered across the surface. The specimen is an irregular fragment, showing no signs of artificial preparation, polishing, or mounting. The preservation is primarily in the form of casts and molds within the consolidated sediment, providing a clear record of the shell's exterior morphology.
