Kepplerites sp. Ammonite Fossil | Lower Callovian, Jurassic | Wiltshire UK | Alice Purnell Collection | Genuine with Certificate

Description

Fossil Type & Species:

This listing features a genuine ammonite fossil of Kepplerites sp., a representative of the Kosmoceratidae family, collected from the Lower Callovian Stage of the Jurassic Period. This well-preserved fossil was discovered in Wiltshire, United Kingdom, and is part of the respected Alice Purnell Collection, known for quality, authenticity, and scientific value.

Geological Formation & Insight:

Kepplerites is a genus of moderately evolute, strongly ribbed ammonites belonging to the Kosmoceratidae, a key group of Jurassic cephalopods. These ammonites are important for biostratigraphic correlation, especially within the Lower Callovian, and are often used by geologists to date layers of marine sediment.

This specimen comes from the Oxford Clay Formation, a rich Middle Jurassic marine deposit that spans much of southern England. The Lower Callovian strata date to approximately 166 to 163 million years ago and represent an ancient epicontinental sea environment — calm, shallow waters ideal for marine life such as ammonites, belemnites, marine reptiles, and bivalves.

The clay-rich sediments of the Oxford Clay preserved marine fossils in fine detail, often including shell ornamentation, suture lines, and original coiling patterns.
