Description

This listing features an authentic Gravesia fossil ammonite from the Upper Tithonian stage, dating to the transition between the Late Jurassic and Early Cretaceous, approximately 150–145 million years ago. This specimen was discovered in Lorraine, France, a region celebrated for its fossil-rich sedimentary formations. It comes from the Alice Purnell Collection, which is known for its high-quality, well-documented fossil specimens.

Gravesia is a genus of extinct ammonite molluscs known for their elegant, compressed shells and fine ribbing. These cephalopods thrived in shallow marine environments, and their evolutionary lineage makes them important biostratigraphic markers, especially around the Jurassic-Cretaceous boundary. The specimen here offers a fine example of Gravesia shell morphology and preservation.

Geological Context: The Upper Tithonian Stage is the final stage of the Jurassic, closely approaching the Jurassic-Cretaceous boundary. The Lorraine region, located in northeastern France, was covered by warm epicontinental seas during this time, allowing for the exceptional preservation of marine fauna. Ammonites like Gravesia are used by geologists and palaeontologists to help date and correlate rock layers across Europe.
