Ammonitida - Cleoniceras Ammonite

Cleoniceras Ammonite Pair on Bronze 198mm

£1,192.00 GBP

A fine ammonoid cephalopod phragmacone (shell), the exoskeleton fossilised as the soft tissues were broken down by bacteria, the empty chambers of the remaining phragmacone, possibly already having traces of gaseous sediments which under the advantageous environment of pressure and temperature create through a process of per-mineralisation, where mineral-rich water forces through the tissue of the phragmacone depositing mineral elements to aid the growth of marvellous coloured quartz crystal we see unearthed today.

A Cleoniceras ammonite precisely cut into two halves forming a matched pairing, these polished to a high standard, revealing the fascinating interior of shell growth, the chambers which over millennia have filled with naturally forming minerals of quartz, calcites and limestone fossil sediment from the seabed of the Cretaceous era. The colours to this fossil shell are particularly attractive, the last three chambers contain the sea bed sediment now metamorphosed into limestone. The remaining chambers of quartz spiralling and diminishing in size reflecting the growth of the ammonite from the smallest central chamber.

Ammonites are part of the Ammonitida of marine invertebrates. These were fascinating creatures dwelling in shallow to mid-depth oceans and believed to be aggressive creatures as squids of today. With large eyes and remarkable vision, they hunted their prey at depths where little or no light penetrates the deep oceans. The Cephalopod using its long tentacles would locate prey much like extant squids and nautili Pompilius which can be found in the Pacific today.

An excellent conserved fossil ammonite, cut into two halves, exhibiting both sections polished perfectly flat and revealing the wonders of per-mineralisation which has taken place over millions of years. Each open chamber space has been replaced by calcite and Quartz. This is created by a hydro-thermal activity, this is usually associated with volcanism.
