Description
Holcophylloceras (Holcophylloceras) mediterraneum Fossil Ammonite – Aalenian, Jurassic – France
About the Fossil:
This beautifully preserved Holcophylloceras (Holcophylloceras) mediterraneum ammonite fossil originates from the Aalenian stage of the Middle Jurassic (~174-170 million years ago) and was discovered in France. Holcophylloceras is a genus of phylloceratid ammonites, distinguished by their highly involute, smooth shells with complex, intricate suture patterns. Unlike ribbed ammonites, phylloceratids have streamlined shells, suggesting they were strong swimmers, possibly inhabiting deeper marine environments.
During the Middle Jurassic, ammonites like Holcophylloceras mediterraneum thrived in warm, shallow to deep marine ecosystems, playing a crucial role in the ancient oceanic food chain. The Aalenian deposits of France are well-known for producing well-preserved ammonite fossils, helping researchers and collectors understand the diversity of Jurassic cephalopods.
