Description

Genuine Flabellisphinctes villanyensis Ammonite Fossil

This listing is for a genuine Flabellisphinctes villanyensis ammonite fossil from the Inferior Oolite Group, dating to the Middle Jurassic, Upper Bajocian stage, from Dorset, UK. This fossil is a carefully chosen specimen, and the photo shows the actual ammonite you will receive, making it ideal for collectors who want to view the exact fossil before purchase.

Middle Jurassic Fossil from Dorset

This ammonite comes from the Middle Jurassic, specifically the Upper Bajocian, approximately 168 to 166 million years ago. During this time, much of what is now southern England was covered by warm, shallow marine seas. These Jurassic seas supported a rich variety of marine life, including ammonites, belemnites, bivalves, brachiopods, gastropods, crinoids, echinoids, corals, and marine reptiles.

Dorset is one of the most famous fossil-producing counties in the UK, with a long history of important Jurassic discoveries. While the Dorset coast is especially well known, inland and regional exposures of Jurassic strata also preserve significant fossil material. Fossils from the Inferior Oolite Group are particularly valued because they represent classic Middle Jurassic marine environments and often preserve ammonites that are useful for dating and correlating rock layers.

Inferior Oolite Group Geology

The Inferior Oolite Group is a major Middle Jurassic rock unit in southern England, composed mainly of fossiliferous limestones, marls, sandy limestones, and iron-rich sediments. The name “oolite” refers to small rounded carbonate grains called ooids, which formed in warm, shallow, agitated marine waters. These sediments accumulated on ancient sea floors and later hardened into limestone.

The Inferior Oolite Group is especially important in British palaeontology because of its diverse ammonite faunas. Ammonites from these beds are widely used in biostratigraphy, allowing geologists to divide the Jurassic rock record into precise zones and subzones. A fossil with a named species and clear geological unit is therefore of strong collector and educational interest.

Fossil Type and Species

Flabellisphinctes villanyensis is an extinct ammonite species. Ammonites were marine cephalopods related to modern squid, cuttlefish, octopus, and nautilus. They lived in coiled chambered shells, with the living animal occupying the final body chamber and the earlier chambers helping with buoyancy.

The genus Flabellisphinctes is associated with Jurassic ammonite faunas and is recognised for its coiled shell form and ribbed ornamentation. Depending on preservation, specimens may show fine to strong ribs crossing the whorls, an evolute spiral form, and natural shell features that reflect the animal’s growth. These details make Flabellisphinctes ammonites attractive to collectors and valuable for study.

Scientific and Collector Interest

Ammonites such as Flabellisphinctes are important index fossils because they evolved rapidly and were widely distributed through ancient seas. Their changing shell forms allow palaeontologists and geologists to compare rock layers between different regions. Jurassic ammonites are especially popular with collectors because they combine scientific importance with beautiful natural geometry.

This specimen is a desirable addition to collections focused on British fossils, Dorset fossils, Jurassic ammonites, Inferior Oolite fossils, fossil cephalopods, and named invertebrate species. Its Upper Bajocian age gives it a clear place within the Middle Jurassic fossil record, while its Dorset origin adds strong locality interest.

Display and Educational Use

This Flabellisphinctes villanyensis ammonite fossil would display well in a fossil cabinet, natural history collection, study tray, classroom resource, geology display, or museum-style collection. It is suitable for both new collectors and experienced fossil enthusiasts looking for a well-identified Jurassic ammonite from the UK.

Full sizing can be seen in the photo, so please refer to the image for exact scale and dimensions. As a natural fossil specimen, variations in colour, matrix, surface texture, preservation, and detail are part of its individual character.

Authenticity and Certificate

This fossil is a genuine specimen and includes a Certificate of Authenticity lifetime guarantee generic card. The photograph shows the actual Flabellisphinctes villanyensis ammonite you will receive, allowing you to view the specimen’s condition, shape, detail, and natural preservation before ordering.
