Ammonitida - Hoplitidae

Cleoniceras Ammonites on Bronze 265mm

£992.00 GBP

A fine Cleoniceras pair of ammonites measuring 265mm, this 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.

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 Each open chamber space has been replaced by calcite and Quartz.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.

Genus: Cleoniceras ammonite, family Hoplitidae.
