7″ Euaspidoceras freii Fossil Ammonite – Lower Oxfordian Stage, Jurassic – Calvados, France – Alice Purnell Collection

Description

This listing features a stunning 7-inch fossil ammonite of the species Euaspidoceras freii from the Lower Oxfordian stage of the Jurassic period, discovered in the renowned fossil-rich region of Calvados, France. This specimen is part of the distinguished Alice Purnell Collection, known for housing well-documented and scientifically significant fossils.

Euaspidoceras freii is a species within the family Aspidoceratidae, recognised for their large, robust shells and complex suture patterns. These ammonites thrived in warm Jurassic seas approximately 163 to 157 million years ago. The shells are typically ornamented with strong ribs and tubercles, features that served both hydrodynamic and possibly defensive purposes.

As a free-swimming marine cephalopod, Euaspidoceras would have played an important role in the food chain of its time, likely preying on small marine organisms. Its beautifully preserved spiral and detail-rich features make this ammonite a centrepiece specimen for any fossil collection.

Geological Context: The Lower Oxfordian Stage marks the early part of the Late Jurassic and is well represented in northern France. The Calvados region, located in Normandy, is celebrated for its well-exposed marine limestones and marls that yield abundant ammonite fossils. During the Oxfordian, this area was submerged beneath shallow seas ideal for the deposition and preservation of marine life.
