Description

This Xipheroceras Fossil Ammonite Full Calcite is an extraordinary and rare Jurassic specimen, discovered at Stonebarrow Cliff, Charmouth, Lyme Regis, Dorset, UK, part of the world-famous Jurassic Coast. Featuring beautifully preserved ammonite ribbing combined with complete calcite replacement, this fossil is a truly unique find, offering both scientific and aesthetic appeal.

Geology & Formation: Xipheroceras is a genus of ammonites from the Lower Jurassic (Lower Lias) period, dating back approximately 190 million years. Found within the Black Ven Marls, these fossils have undergone remarkable mineralization, with the entire shell being replaced by calcite, preserving its detailed structure in crystal form. This process occurs when mineral-rich waters slowly percolate through sedimentary layers, replacing the original material with calcium carbonate, creating a stunningly detailed fossil with a translucent or golden calcite glow.

Discovery & Collection Information: This specific ammonite was discovered by our own team members, Alister and Alison, on 14 January 2025. It has been carefully cleaned, prepped, and treated by Alison, ensuring the highest quality preservation of both the ammonite structure and the intricate calcite formation. It originates from the Alice Purnell Collection, one of the most prestigious fossil collections globally.
