7.4" Polished Fossil Nautilus (Cymatoceras) and Ammonite - Madagascar
This is a beautiful 7.4" fossil nautilus of the genus Cymatoceras, collected from the Cretaceous age deposits of Madagascar. It is polished to highlight the details. These nautiloids are much rarer than the ammonites so frequently seen.
There is a naturally associated, iridescent ammonite (Gaudryceras sp.) within the rock at the opening of this nautilus, which has been polished to a glossy finish as well. Comes with a large acrylic/metal display stand.

About Nautilus Fossils
autilus is a classic shelled cephalopod with a fossil history spanning more than 500 million years. Fossil nautilus shells are instantly recognizable by their tightly coiled, chambered structure, created as the animal grew and adjusted buoyancy using a central siphuncle. These fossils often preserve beautiful suture patterns, internal chambers, and sometimes even traces of original nacre. Found in marine deposits worldwide and frequently mineralized with calcite or chalcedony, fossil Nautilus specimens provide a striking glimpse into ancient seas and showcase one of the most enduring designs in natural history.
