Description

Fossilized Saint-Jacques Shell Plaque

Gigantopecten restitutensis

Early Miocene, Burdigalian (approx. 20-16 million years ago)

Lacoste Quarry, Vaucluse, France


17 x 16 x 7 inches (43.1 x 40.6 x 17.8 cm). 84 pounds (38.1 kg).


The shells in this specimen's decorative cluster display are well preserved and intact, most with both halves articulated. The shells are exposed on a square, trimmed matrix.

Gigantopecten restitutensis — also known as Saint-Jacques shells — were a species of giant scallop that thrived all over the world during the Early Miocene, from approximately 20 million to 16 million years ago.


Like today's extant scallops, Gigantopecten restitutensis was a saltwater mollusk that lived on the sea floor, filtering and eating plankton. These bivalves had relatively large shells, growing to lengths of over five inches (13 cm) and widths topping six inches (15 cm). Because of the considerable size and fragility of Gigantopecten fossils, their removal from the surrounding rock matrix represents excavation and preparatory work of the highest caliber.
