RARE Fossil Ammonite Eopachydiscus isculensis | Campanian Cretaceous | Menabe Madagascar | Certified Genuine Specimen

£48.00

Presenting a RARE Fossil Ammonite, Eopachydiscus isculensis, from the Campanian Stage of the Upper Cretaceous, originating from Menabe, Madagascar. This large and detailed ammonite specimen represents an extinct marine cephalopod that once inhabited the warm epicontinental seas of the southern hemisphere.

This carefully selected piece showcases excellent preservation and classic morphological features typical of the genus. Ideal for serious collectors, researchers, or enthusiasts, this ammonite is both a scientifically significant and visually impressive addition to any fossil collection.

 

Geological & Palaeontological Details:

  • Species: Eopachydiscus isculensis
  • Geological Period: Cretaceous
  • Geological Stage: Campanian (~83.6 to 72.1 million years ago)
  • Locality: Menabe, Madagascar
  • Depositional Environment: Shallow marine carbonate platform, rich in bioclastic and calcareous sedimentation
  • Order: Ammonitida
  • Superfamily: Desmoceratoidea
  • Family: Pachydiscidae
  • Biozone: Commonly correlated with the Globotruncanita elevata and Globotruncana ventricosa biozones in global stratigraphy
  • Identification: The species was first described by Redtenbacher (1873), later revised in Cretaceous faunal studies of the southern Tethys region

 

Morphological Features:

  • Large, thickly discoidal shell with moderately involute coiling
  • Broad rounded whorls with distinct ribbing
  • Smooth ventral keel typical of the genus
  • Calcite-preserved chambers visible in sectioned areas
  • Cream and beige patina with natural mineral infill and weathering textures

 

Notable Information:

  • A classic ammonite taxon from the Campanian, used in biostratigraphy for age-dating marine sedimentary sequences
  • Often found in association with other Pachydiscidae and marine reptiles in Madagascar fossil sites
  • Represents a diverse lineage of pachydiscid ammonites with a near-global distribution during the Late Cretaceous

 

Authenticity & Presentation:

  • 100% genuine fossil specimen, not a replica
  • Supplied with a Certificate of Authenticity
  • Photo is of the actual fossil for sale
  • Scale cube = 1cm for accurate sizing reference

Cretaceous Information

The Cretaceous Period (145–66 million years ago) was the final era of the Mesozoic, marked by the dominance of dinosaurs and the rise of flowering plants. It had a warm, greenhouse climate, with high sea levels that created vast shallow inland seas. Marine life flourished, including mosasaurs, ammonites, and rudist reefs, while the land was ruled by iconic dinosaurs like Tyrannosaurus rex, Triceratops, and Spinosaurus. Mammals and birds diversified, and insects thrived. The period ended with the mass extinction event, likely caused by an asteroid impact, wiping out the dinosaurs and paving the way for the rise of mammals in the Cenozoic.
