Kepplerites galilei Ammonite Fossil | Lower Callovian, Jurassic | Cotswolds Water Park, Gloucestershire UK | Alice Purnell Collection

Description

Fossil Type & Species:

This listing features a genuine ammonite fossil of Kepplerites galilei, an important Middle Jurassic ammonite species from the Lower Callovian Stage. This specimen was discovered in the fossil-rich layers of Cotswolds Water Park, Gloucestershire, United Kingdom, and originates from the Alice Purnell Collection, recognised for its high-quality and scientifically valuable British fossils.

Geological Formation & Insight:

Kepplerites galilei is a species within the Kosmoceratidae family, a group of ammonites known for their strong ribbing, involute shells, and importance in biostratigraphy. As a key index fossil for the Lower Callovian, K. galilei helps geologists date marine sediments with high precision.

This fossil is from the Oxford Clay Formation, one of the UK’s most famous Jurassic marine deposits, dating to approximately 166 to 163 million years ago. During this period, much of southern Britain was submerged beneath a warm, shallow epicontinental sea. These calm conditions led to fine clay deposition, which preserved ammonites and other marine life in remarkable detail.

Cotswolds Water Park is a well-known collecting site within this formation, producing numerous beautifully preserved cephalopod fossils, including ammonites with intact ribbing, suture patterns, and shell morphology.
