Pelekodites spatians Ammonite Fossil France Jurassic Upper Bajocian COA Mougon Deux-Sèvres Marine Specimen

Description

Genuine Pelekodites spatians Ammonite Fossil

This listing is for a genuine Pelekodites spatians ammonite fossil from Mougon, Deux-Sèvres, Nouvelle-Aquitaine, France. Dating from the Upper Bajocian Stage of the Middle Jurassic, this specimen represents a classic European Jurassic marine cephalopod from the warm shallow seas that once covered western France.

Pelekodites spatians is a collectible ammonite species with strong appeal for fossil collectors, natural history enthusiasts, educational displays, and anyone interested in Middle Jurassic palaeontology. Its named species, French locality, Upper Bajocian age, and attractive ammonite form make it a desirable fossil for a carefully labelled collection. This fossil is a carefully chosen piece, and the photograph shows the actual specimen you will receive. Full sizing can be seen in the photo.

Geology, Age and French Locality

This ammonite comes from Mougon, in the department of Deux-Sèvres, within the Nouvelle-Aquitaine region of western France. This area is known for Jurassic marine sedimentary deposits, including limestones, marls, and fossil-bearing beds formed in ancient shelf-sea environments. During the Middle Jurassic, this part of France lay beneath warm marine waters connected to wider European seas.

The fossil is Upper Bajocian in age, placing it within the later part of the Bajocian Stage of the Middle Jurassic, approximately 169 to 168 million years old. The Bajocian was an important interval in ammonite evolution, when many ammonite groups diversified rapidly across the shallow seas of Europe. Because ammonites evolved quickly and were widely distributed, they are highly useful for dating and correlating Jurassic rock layers.

The fossil-bearing deposits of Deux-Sèvres record a marine environment rich in shelled invertebrates and other sea life. Sediments accumulated on the sea floor over millions of years, preserving the remains of ammonites, belemnites, bivalves, brachiopods, gastropods, echinoids, and other marine organisms.

Fossil Type and Species Details

Pelekodites spatians was an ammonite, an extinct marine mollusc belonging to the cephalopod group. Ammonites are related to modern squid, cuttlefish, octopus, and nautilus, although ammonites themselves became extinct at the end of the Cretaceous Period. Like other ammonites, Pelekodites possessed a coiled external shell divided internally into chambers. The living animal occupied the final body chamber, while the earlier chambers helped regulate buoyancy as it moved through the water.

Pelekodites is part of the diverse ammonite fauna associated with Middle Jurassic European marine deposits. Specimens of this type typically display a planispiral coiled shell, visible whorl development, and ornamentation that may include ribbing or growth features depending on preservation. These shell characteristics are important in ammonite identification and make named specimens particularly interesting for collectors.

Scientific classification places ammonites within Phylum Mollusca, Class Cephalopoda, Subclass Ammonoidea, and Order Ammonitida. Pelekodites is generally associated with the Oppeliidae ammonite lineage, a group known for often compressed, refined shell forms and important Middle Jurassic representatives.

Ancient Jurassic Marine Environment

During the Upper Bajocian, the region now known as Nouvelle-Aquitaine was covered by warm, shallow marine waters. These seas formed part of a broad European shelf environment where carbonate-rich sediments, shelly seabeds, and marine muds accumulated. The conditions were ideal for ammonites and many other marine invertebrates, creating fossil-rich deposits that are still studied and collected today.

Pelekodites spatians would have lived in this ancient sea as part of a complex Jurassic ecosystem. Its chambered shell helped it control buoyancy, allowing it to move through the water column while feeding, avoiding predators, and occupying a specialised marine niche. The same waters would have supported belemnites, bivalves, brachiopods, gastropods, echinoids, crustaceans, fish, and marine reptiles.

Ammonites are among the most iconic fossils of the Jurassic Period because of their distinctive spiral shells and their importance in geological dating. A specimen from Mougon, Deux-Sèvres offers both visual appeal and strong geological provenance, linking the fossil directly to the marine history of western France.

Collectible French Jurassic Ammonite

This Pelekodites spatians ammonite fossil is an excellent addition to a fossil collection, educational display, natural history cabinet, or geology-themed gift selection. Its Upper Bajocian age, Mougon locality, French origin, and named species identification make it especially suitable for collectors of European ammonites, Jurassic fossils, and scientifically labelled specimens.

This fossil is a genuine specimen and includes a Certificate of Authenticity lifetime guarantee generic card. The photograph shows the actual fossil you will receive, making this a carefully selected and accurately represented collector’s piece from the Middle Jurassic marine deposits of Mougon, Deux-Sèvres, Nouvelle-Aquitaine, France.
