Ammonitida - Hoplitidae

Opal Cleoniceras Ammonite 76mm

£98.00 GBP

an exotic opalescent Cleoniceras ammonite discovered in the tropical island in Mahajanga jungle lying off the coast Madagascar and this is where some of the finest and colourful specimens are discovered in the world today. Richly detailed minerals like quartz develop in the earth's sedimentary layers creating unique depositions that help the spectacular mineralisation seen here, some pieces outcrop on the surface and many have to be mined

The Ammonite, similar tot he modern squid had large eyes and remarkable vision, they could easily hunt prey at a depth where little or no light penetrates the deeper ocean. The Cephalopod would attain its prey using long tentacles. Prey such as other crustaceans and fish, much like the modern-day Nautilus Pompilius which can be found in the Pacific and Indian oceans.

A few years ago off the Great Barrier Reef at depths between 200 to 400 meters, sightings of the Nautilus Pompilius were made, showing the pressures these Cephalopods can attain. The Ammonites extinction is dated around 74 million years, pre the great mass extinction of around 65 million years. Ammonites are important index fossils, it is often possible to link the sediment layer in which they are found to specific geological time periods. The largest ammonite to date is around 2.5 meters in diameter from Germany.
