For sale is an authentic Trimarginites trimarginites ammonite fossil from the Middle Oxfordian stage of the Jurassic Period, discovered in Charente, France. This beautifully preserved specimen displays the distinctive ribbed shell and coiled morphology characteristic of the Trimarginites genus, making it an exceptional addition to any fossil collection.

Geology & Fossil Type:

This ammonite originates from the Middle Oxfordian, a stage within the Upper Jurassic, dating back approximately 160 million years. The Oxfordian period was marked by warm, shallow seas, which provided an ideal environment for ammonites to thrive. Fossils from this period are crucial for biostratigraphic dating, allowing geologists to correlate rock layers worldwide.

Trimarginites trimarginites belonged to the subclass Ammonoidea, an extinct group of marine mollusks closely related to modern squids and octopuses. These ammonites had intricately ribbed shells that provided structural support and protection from predators. Their chambered shells allowed for buoyancy control, enabling them to move efficiently through prehistoric oceans.

Description

Fossil Identification

This listing is for a Trimarginites trimarginites fossil ammonite, identified as Middle Oxfordian, Jurassic. The specimen is associated with Chatente, France, and forms an appealing addition to a fossil collection focused on ammonites, Jurassic palaeontology and scientifically identified marine fossils. The repeated name in the identification reflects the supplied product identification: Trimarginites trimarginites.

Geological Context

The Oxfordian is a Jurassic stage, placing this fossil within the Jurassic geological period. Ammonites are extinct marine cephalopods known from the fossil record and are especially valued by collectors for their importance in reconstructing ancient marine environments and studying changes through geological time. As cephalopods, ammonites are related in a broad zoological sense to modern nautiluses, squids, cuttlefish and octopuses, although ammonites themselves are extinct.

Ammonite fossils are widely collected for their scientific and display appeal. Their shell architecture, coiling, surface details and suture patterns can provide important information for identification and comparison. Trimarginites trimarginites offers a named fossil identification for collectors interested in Jurassic ammonites and the diversity of fossil cephalopods from the Oxfordian interval.

Locality and Collection

The associated locality is Chatente, France. French Jurassic fossils are of strong interest to collectors who enjoy linking a specimen with a named European locality and geological interval. This specimen is from the Alice Purnell Collection, giving it a documented collection context for display, study or inclusion in a specialist fossil cabinet.

Display and Collecting

This Trimarginites trimarginites ammonite is suited to fossil collectors, Jurassic geology enthusiasts, palaeontology students, educators and anyone building a display of identified ammonites. It can be presented as part of a themed collection featuring Jurassic fossils, Oxfordian specimens, French localities or extinct marine life. The identification and geological wording make it suitable for a labelled display alongside reference material covering ammonite evolution, Jurassic seas and fossil classification.

The specimen may also appeal to collectors seeking a distinctive educational object with a direct connection to deep geological time. Ammonites are frequently used in palaeontological study because they are widespread in the fossil record and can help illustrate how fossil groups are named, compared and placed within geological succession.
