Description
Neophylloceras (Neophylloceras) ononense Fossil Ammonite – Hauterivian, Cretaceous – Madagascar
About the Fossil:
This exceptionally preserved Neophylloceras (Neophylloceras) ononense ammonite fossil originates from the Hauterivian stage of the Early Cretaceous (~133-129 million years ago) and was discovered in Madagascar. Neophylloceras is a genus of phylloceratid ammonites, known for their smooth, involute shells with intricate, highly lobed suture patterns. Unlike ribbed ammonites, phylloceratids have a more streamlined shell, suggesting they were active swimmers in deeper marine environments.
During the Early Cretaceous, ammonites like Neophylloceras ononense inhabited warm, tropical seas, where they played a vital role in the marine ecosystem. Their highly complex suture patterns and distinctive morphology make them particularly fascinating for both collectors and researchers. The Hauterivian-aged deposits of Madagascar are renowned for producing beautifully preserved ammonite specimens, providing crucial insights into ancient cephalopod evolution.
