Gigantopecten restitutensis — also known as a Saint-Jacques shell — is a species of scallop that thri❀ved all over the world durin💮g 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 heights of over 5 inches (13 cm) with widths topping 6 inches (15 cm). Because of the considerable size and fragility of Gigantopecten fossils, their removal from the surrounding rock matrix ﷺrepresents excavation and preparatory▨ work of the highest caliber.
