Description

This listing features a rare and beautifully preserved Stephanoceras humphriesianum Ammonite Fossil, dating back to the Middle Bajocian Stage of the Jurassic Period, approximately 170 million years ago, from the B. Oxford region, United Kingdom. This specimen measures 6 inches in diameter and comes from the prestigious Alice Purnell Collection.

Ammonites are extinct marine molluscs belonging to the subclass Ammonoidea. Recognised for their iconic spiral shells, these creatures thrived in the Earth’s oceans for over 300 million years before going extinct at the end of the Cretaceous period. The genus Stephanoceras is known for its intricate ribbing and robust shell morphology, making it a highly desirable fossil among collectors and researchers alike.

The Bajocian Stage, part of the Middle Jurassic, saw a flourishing of ammonite diversity and abundance. The region of B. Oxford in the UK is renowned for producing fine ammonite specimens preserved in limestone and marl-rich sediments.

This fossil has been meticulously cleaned and prepared to highlight its beautiful external shell features. A true collector’s piece, it captures the grandeur of Jurassic marine life in exceptional detail.
