Kepplerites Ammonite Fossil from Kellaways Beds Callovian Jurassic Latton Quarry Cotswold Water Park Swindon UK


£ 14.40

GEOLOGICAL CONTEXT AND PROVENANCE

This specimen is a genuine Kepplerites ammonite fossil from the Kellaways Beds
of the Callovian Stage, Middle Jurassic (approximately 166 – 163 million years ago). It originates from Latton Quarry, Cotswold Water Park, Swindon, UK, a well-known fossil locality that has produced an abundance of exceptionally preserved Jurassic ammonites. These deposits represent shallow marine environments of the epicontinental seas that once covered large parts of southern Britain during the Middle Jurassic.

The Callovian is internationally recognised for its ammonite diversity and biostratigraphic precision. Kepplerites is one of the key genera used to define Callovian ammonite zones, making this specimen important both scientifically and for collectors.

FOSSIL TYPE AND SPECIES INFORMATION

The genus Kepplerites belongs to the Order Ammonitida, Superfamily Stephanoceratoidea, and Family Stephanoceratidae. Ammonites of this group are noted for their complex suture lines and strong ribbing, features which help palaeontologists establish fine-scale biostratigraphic zones within Jurassic sediments. Kepplerites is a significant marker genus for the lower Callovian ammonite biozones, specifically the Kepplerites keppleri Zone, making this fossil an index species of international importance.

MORPHOLOGICAL FEATURES

This specimen exhibits the classic traits of the genus:


• Strongly Ribbed Shell – Prominent, radiating ribs run across the flanks, enhancing the overall texture.
• Tubercles and Ornamentation – Some ribs bear small nodules or tubercles, a feature distinctive of many Kepplerites species.
• Planispiral Coiling – The tightly coiled whorls form a compact spiral typical of Jurassic ammonites.
• Suture Pattern – Although subtle on the surface, Kepplerites are known for their complex suture lines, which reflect evolutionary advancements within the Ammonitida.

These features make the fossil both scientifically valuable and visually appealing, adding to its desirability for collectors.

DEPOSITIONAL ENVIRONMENT

The Kellaways Beds are composed of sandy and clay-rich sediments deposited in a shallow marine setting during the Callovian. The environment supported abundant ammonites, bivalves, and marine reptiles, with conditions favourable for fossilisation. The fine-grained sediments preserved ammonites like Kepplerites with exceptional detail, allowing both their ornamental and structural features to survive through geological time.

SCIENTIFIC AND COLLECTOR SIGNIFICANCE

Owning a Kepplerites ammonite from Latton Quarry is of great significance for both collectors and researchers:


• Index Fossil Status – Kepplerites is critical in defining the lower Callovian biozones.
• Aesthetic Appeal – Its striking ribbing and form make it an excellent display specimen.
• Provenance – Fossils from Latton Quarry are highly regarded due to their excellent preservation and scientific value.
