An attractive Ammonite on bronze, extracted from the High Atlas where it was unearthed from the Cretaceous fossil layers, conserved and prepared with many hours of processing to reach this final exhibit stage. The custom bronze mount designed and produced in England is crucial for each fine creation. Revitalising these fascinating, extinct marine molluscs. Presenting them in this dramatic way.

The skill of our technicians is obvious to see in the illustrations and we feel this creates a strong interior decoration, something we have been striving for since first discovering these large cephalopods in the mountains of Africa over 25 years ago. Our ammonites on bases have been placed in fine establishments around the United Kingdom and further afield. The elements of natural limestone fossils and bronze metals work well together and compliment each other, the ancient revitalised on the new clean lines of the base create a very pleasing statement.

The natural history of ammonites is fascinating. Recently ammonites have been pictured using the European Synchrotron Radiation Facility (ESRF) in Grenoble by a team of French and American researchers. They have found ammonite teeth, radula around the tongue of the cephalopod. This adds to the theories of how the ammonites lived, what they ate, leading to where they ate. Plankton have been found using the x-ray. The theory is that ammonites were pelagic nektonic marine animals and that if there food was mainly plankton this explains why the became extinct towards the end of the cretaceous period.

Near the KT boundary, the mass extinction event of the Cretaceous which put pay to the dinosaurs around 65 to 64 m.y.a. the environment of the oceans seemed to be changing, the oxygen levels could have been changing, climate shifts and cooler and warmer periods affected the planktonic habitant, reducing plankton and thus effected the ammonites sending them into a decline also.

Ammonites are becoming increasingly more difficult to cull from the Atlas Mountain fossil beds in the region due to recent dam placement flooded vast areas over the fossil layers. Making collecting more difficult for the indigenous fossil hunters. Necessitating hunting and extracting fossil layers higher into the mountain range. This means more laborious methods and techniques which make the extraction a very slow process, eventually these beds will expire, all too common for fossil hunters with ever changing and developing environments.
