A one of kind and beautifully prepared Asteroceras ammonite presented on our in-house custom-built bronze stand designed for easy removal for study and transportation.

Found and prepared from within the original matrix or British limestone bedrock boulder from the once fine mud beds of the Jurassic seabed, now transformed into a piece of historical art.

Discovering an ammonite of this calibre, completeness, size and of this particular specimen Asteroceras is an extremely rare event with the preservation allowing for the preparation of this quality for this uncommon specimen, a truly important museum-quality specimen.

With vivid suture patterning, excellent colours and calcite variations that have developed within the cephalopods internal structure over millions of years, helping to provide insight into the internal morphology of this Asteroceras putting this piece in the top 5% of best British Asteroceras discoveries too date.

Ammonites are becoming increasingly more difficult to gain, particularly the best of the best, from the fossiliferous coasts of the United Kingdom. Our shores may crumble inexorably towards the sea, creating landfalls and new opportunities for collecting, however, these types of rarity and quality remain in short supply. Laborious collecting and preparation techniques make the extraction arduous and time-consuming, an all too common fact of fossil collection today in an ever-developing and changing the environment of Britain.
