HOLCOPHYLLOCERAS SP. FOSSIL AMMONITE – OXFORDIAN, JURASSIC – MADAGASCARABOUT THE FOSSIL:This exceptionally preserved Holcophylloceras sp. ammonite fossil originates
from the Oxfordian stage of the Late Jurassic (~163-157 million years ago) and was discovered in Madagascar. Holcophylloceras is a genus of phylloceratid ammonites, characterized by their highly involute, smooth shells with intricate, lobed suture patterns. Unlike heavily ribbed ammonites, phylloceratids have a more streamlined shell, suggesting they may have been strong swimmers in deeper marine environments.During the Late Jurassic, ammonites like Holcophylloceras sp. thrived in warm, shallow to deep marine ecosystems, playing a crucial role in ancient oceanic food chains. The Oxfordian deposits of Madagascar are recognized for their rich ammonite-bearing formations, providing paleontologists and collectors with insights into the diverse cephalopod fauna of the Jurassic seas.GEOLOGY & FORMATION:
• Geological Age: Oxfordian, Late Jurassic (~163-157 million years ago)
• Formation: Marine sedimentary deposits
