This beautifully preserved specimen displays the distinctive ribbed shell and coiled morphology characteristic of the Idoceras genus, making it a valuable addition to any fossil collection.

Geology & Fossil Type:

This ammonite comes from the Middle Oxfordian, a stage of the Upper Jurassic, dating back approximately 160 million years. The Oxfordian period was marked by widespread shallow seas, where ammonites thrived. These fossils play a crucial role in biostratigraphy, helping geologists date and correlate Jurassic rock layers.

Idoceras belonged to the subclass Ammonoidea, an extinct group of marine mollusks closely related to modern squids and octopuses. Ammonites were free-swimming marine creatures that used their chambered shells for buoyancy control, allowing them to move efficiently through prehistoric seas. The ribbed shell of Idoceras helped protect it from predators and provided structural support for deep-sea navigation.

Description

Fossil Identification

This listing presents an IDOCERAS fossil ammonite identified as Middle Oxfordian, Jurassic, with the specimen location given as Chatente, France. Ammonites are extinct marine cephalopods recognised for their coiled shell form and are valued by collectors for their distinctive fossilised structure, scientific interest and connection to Earth’s deep geological history.

The name IDOCERAS is an important feature of this specimen’s identification. The supplied data identifies it specifically as an IDOCERAS fossil ammonite rather than simply a generic ammonite, making it a useful addition for collectors who focus on named fossil groups, Jurassic material or ammonite diversity.

Geological Interest

The Middle Oxfordian belongs to the Jurassic Period. Oxfordian ammonites are of particular interest in palaeontology because ammonite fossils can assist with studying changes in marine environments and comparing rocks and fossil assemblages through geological time. Their tightly coiled shells, chambered construction and visible surface details make ammonites especially appealing for display, educational collections and fossil study.

This specimen is listed from Chatente, France, giving it a defined French collecting location within the supplied product information. The identification and geological designation provide useful context for collectors interested in Jurassic fossils and the ammonite record.

Collection Details

The fossil is from the Alice Purnell Collection. It is suited to a personal fossil cabinet, natural history display, educational setting or collection centred on Jurassic palaeontology. Its named identification and geological placement make it suitable for comparison with other ammonites and fossils from the Jurassic Period.

The specimen can be viewed in the listing photographs, which show the item offered for purchase. The photograph shows the actual specimen you will receive.

Authenticity and Certificate

This Fossil is a genuine specimen and Includes a Certificate of Authenticity lifetime guarantee generic card.

The included certificate wording provides supporting documentation for the specimen as a genuine fossil. Collectors may retain the certificate with the specimen as part of their collection records, particularly when cataloguing identified fossils by geological period, location and collection history.

Display and Collector Appeal

An IDOCERAS ammonite offers a combination of scientific naming, Jurassic geological interest and classic fossil appeal. Ammonites are recognisable display pieces because their shell structure creates a strong natural focal point, while their identification makes them more informative than an unnamed decorative fossil. This piece may appeal to ammonite collectors, Jurassic fossil enthusiasts, students of palaeontology, museum-style display makers and anyone interested in the history of marine life.
