Description

Kosmoceras Ammonite Fossil

This genuine Kosmoceras ammonite fossil is identified with the Oxford Clay, Lower Callovian, Jurassic. It comes from the Cotswold Water Park in Gloucestershire, UK, an area recognised for its fossil-bearing geological material and collector interest. The specimen is offered as a natural fossil for display, study and educational collections.

Identification and Geological Context

Kosmoceras is an extinct genus of ammonite, a group of marine cephalopods that lived in the Jurassic seas. Ammonites are valued by collectors for their scientific importance, distinctive fossilised shell forms and connection to the ancient marine environments of the Mesozoic Era. The supplied identification places this specimen within the Oxford Clay and the Lower Callovian stage of the Jurassic.

The Oxford Clay is a well-known Jurassic geological unit associated with fossil preservation. The Lower Callovian forms part of the Middle Jurassic and is an important interval for ammonite research and biostratigraphic study. Kosmoceras specimens are of particular interest to collectors who enjoy Jurassic ammonites, British fossils and material connected with the geology of England.

Locality

The specimen locality is recorded as the Cotswold Water Park, Gloucestershire, UK. This geographic information makes the fossil especially appealing to collectors building regional British fossil displays or researching Jurassic material from Gloucestershire. Its combination of Kosmoceras identification, Oxford Clay association and Lower Callovian age provides useful context for a curated fossil collection.

Collector and Display Appeal

This fossil is suitable for ammonite collectors, Jurassic geology enthusiasts, classroom and educational displays, museum-style cabinets, and anyone interested in the natural history of the United Kingdom. Kosmoceras fossils can be displayed alongside other ammonites, Jurassic fossils or specimens from the Oxford Clay to create a themed geological collection.

The specimen may also be useful as an accessible introduction to ammonite taxonomy, Jurassic palaeontology and the use of fossils in understanding ancient marine ecosystems. Its named genus and geological context provide meaningful information for cataloguing and display without relying solely on decorative appeal.
