Ammonitida - Hoplitidae

Cleoniceras Sutured Ammonite 145mm

£187.00 GBP

A highly sutured and mineral chambered Cleoniceras ammonite measuring 145mm, the saddle having been relieved of Cretaceous period matrix exposing the saddle formation of the ammonite, this has also exposed the suture lines which create the frilly edge around the saddle and mouth aperture, a spectacular hand selected specimen from Madagascar.

These extinct cephalopods part of the ammonoid group and similar to squids, cuttlefish and octopi of today. This particular specimen fossil Cleoniceras exhibits the fine divisions of the cephalopods septa, chamber wall or divisions. Naturally formed here as lighter and darker coloured wavy chamber septa over the honey and treacle colour mineral infill. The sutures are found at the point of divisions of growth, as the ammonite added each new chamber or septa wall a larger suture stage developed. The frilly sutures were the points of attachment of the septa, separating each chamber of the mollusc In the last chamber, the soft body of the mollusc dwelled.

The septa sutures were attached to the inner shell and have left the patterning which is a remarkable event in the natural history of the cephalopod. Once polished the attractive markings become apparent if the fossil has preserved well, many times this is not the case. Beautiful examples are rare, many more ammonites are not so attractively marked.

The sutured chambers are filled with minerals, often quartz, calcites and jaspers which are all semi-precious minerals of the mineral kingdom. The fossilised shell itself has a good three dimensional or inflated shape and is of a good size for the type. A recommended investment ammonite.
