Cretaceous Ammonite Pair Fossils from Madagascar Genuine Display Specimens with COA

Authentic Cretaceous Ammonite Pair – Madagascar

This listing features a genuine matched pair of ammonite fossils from the Cretaceous Period, collected in Madagascar, one of the world’s most important sources of beautifully preserved ammonites. The pair has been carefully selected for balance, visual harmony, and preservation quality, making it ideal for display. The photographs show the exact specimens you will receive, and full sizing details are provided in the listing images. As with all our fossils, these ammonites are 100% genuine and supplied with a Certificate of Authenticity.

Geological Age and Setting – The Cretaceous Seas

The Cretaceous Period, spanning approximately 145 to 66 million years ago, represents the final chapter of the Age of Dinosaurs and a time when ammonites reached extraordinary diversity and abundance in the world’s oceans. Madagascar lay within warm, shallow marine environments, where nutrient-rich waters supported thriving populations of cephalopods.

Sediments deposited during the Cretaceous in this region were ideal for fossil preservation. Rapid burial in fine marine sediments protected ammonite shells from erosion and scavenging, allowing their coiled forms to be preserved in remarkable detail. Fossils from Madagascar are especially prized for their three-dimensional preservation and strong natural definition.

Fossil Type – Ammonites (Paired Specimens)

Ammonites were extinct marine cephalopods closely related to modern squid and cuttlefish. They possessed coiled shells divided into internal chambers, which aided buoyancy and allowed them to inhabit a wide range of marine depths. Their rapid evolutionary rates and widespread distribution make ammonites some of the most important index fossils in geology.

This paired ammonite set highlights classic ammonite characteristics, which may include:

• Well-defined spiral coiling, creating a visually striking symmetry

• Clear ribbing or shell ornamentation, depending on species

• Distinct whorl structure, visible across both specimens

• Natural shell texture and mineralisation, reflecting long-term fossilisation

Paired ammonites are particularly desirable for collectors, as they offer enhanced display possibilities and visual balance, whether framed, mounted, or displayed together in a cabinet.

Madagascar – A World-Class Ammonite Locality

Madagascar is internationally recognised for producing some of the finest Cretaceous ammonites available on the market today. The island’s sedimentary basins have yielded countless museum-grade specimens, many preserved with exceptional clarity and natural colouration.

Ammonites from Madagascar are collected globally for private collections, educational use, and museum displays. Their preservation quality and aesthetic appeal make them especially popular among both seasoned collectors and those new to fossil collecting.

Scientific and Display Significance

Ammonite pairs such as this one are valued for both their scientific relevance and decorative appeal. They provide tangible insight into ancient marine ecosystems while also serving as elegant natural art pieces formed by deep time. This pair is suitable for:

• Fossil and natural history collections

• Educational and teaching displays

• Interior décor with geological interest

• Gifts for fossil and palaeontology enthusiasts

Their durability and visual symmetry make them enduring additions to any collection.
