Preserved in their final pose, these fossils are the ancestors of today's modern (edible) scallop. Both paleontologically and visually intriguing specimens, they are characterized by their distinctive fan shaped shells, composed of two valves that are hinged together. The intricate pattern of ridges and grooves of the shells’ morphology has provided scientific insight into these fossilized scallops' growth and development, whilst the unique and visually striking design of pectens have long been admired by for their beauty, employed as iconographic symbols of femininity in painting and sculpture, and displayed as decorative and design objects. The present Lot is remarkable for its structural design, the scallops' surrounding host rock has been carved away to reveal their detail.
