Large Cut & Polished Ammonite Pair | 19 × 15.5cm | Lower Cretaceous | Madagascar

115 Million Years of Natural Architecture

Ammonites were cephalopod molluscs — relatives of today's nautilus and squid — that dominated the world's oceans for over 300 million years before their extinction at the end of the Cretaceous period. Named after the ram-horned Egyptian god Ammon, whose coiled horns their shells resemble, they ranged in size from a few millimetres to over two metres in diameter. This matched pair, sourced from Madagascar and dating to the Lower Cretaceous approximately 115 million years ago, has been cut and polished to reveal the extraordinary internal geometry that made ammonites one of nature's most studied and celebrated fossils.

Cut, Polished & Ready to Display

Sliced precisely through the centre, each half of this pair exposes the intricate septa and suture lines that divided the shell into a series of gas-filled chambers — the buoyancy system that allowed the animal to control its depth in the water column. The iridescent mineralisation characteristic of Madagascan ammonites gives the polished faces a shifting, jewel-like quality in natural light. Supplied with display stands, the pair can be presented together as a matched set or displayed separately.
