The Cleoniceras ammonite has been prepared and conserved using air driven micro pneumatic tools, removing the surrounding matrix (fossil bedrock), to the centre of the whorls, known as the umbilicus. Thus revealing the fine Cleoniceras scientifically and aesthetically. This ammonite displays an attractive array of vivid colours throughout the nacre of the shell flashing bright blue, glaucous greens with strikingly vivid highlights of scarlet red, all created by the refraction of light.
Rare colours found in specimens are maize yellow, amber, blue, glaucous, cerulean, purple, lavender, scarlet red, coral pink and lavender pink. To find the best Cleoniceras specimen for your collection, friend or loved one, you should start looking at the aesthetics. Make sure it is symmetrical, look for flaws on the shells surface, usually these will develop as chips or even filler, large specimens are prone to these anomalies, sometimes these are badly prepared or of a very low grade. Colouration, is it vibrant, does it reflect in low light. One needs to see consistency when looking to buy online and make sure the photographer has caught true reflections of light using standard white lights. In our photography no flash is used therefore one can gain a true likeness of how the ammonite shell and irridescence displays and will display in your collection.
Ammonites are part of the Ammonitida of marine invertebrates. With large eyes and remarkable vision they could easily hunt prey at 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.
