Description
This listing features a RARE 8″ Reineckia anceps Ammonite Fossil from the Middle Callovian Stage of the Jurassic Period, approximately 164–163 million years ago, collected from La Grimaudière, in the Vienne region of France. This impressive fossil is part of the renowned Alice Purnell Collection.
Reineckia anceps is a species of extinct ammonite, a marine mollusc closely related to modern squids, octopuses, and cuttlefish. Distinguished by its broad whorls and ribbed shell structure, Reineckia anceps belonged to a lineage of fast-swimming, predatory cephalopods that once roamed the warm shallow seas of the Jurassic world.
The Callovian Stage (Middle Jurassic) is known for its rich marine biodiversity. During this time, Europe was largely submerged under a shallow epicontinental sea. La Grimaudière, part of France’s fossiliferous belt, yields highly detailed marine invertebrate fossils, including bivalves, brachiopods, and ammonites like Reineckia.
This large 8-inch specimen showcases the ammonite’s characteristic ribbing and preserved coiling. It makes an excellent display fossil for collectors, educational institutions, or natural history enthusiasts. A piece like this is rarely seen on the open market.
