The Asteroceras naturalistically positioned ammonite prepared and contained in the original limestone partial boulder, once the fine muds of the Jurassic seabed, now transformed into limestone. Discovering an ammonite of this calibre, completeness and size, Asteroceras is a rare event. Add to this the completeness, preservation and quality of the preparation of this uncommon specimen type exhibiting suture patterning, excellent colours of calcite variations which have developed within the cephalopods shell and fossilised over millions of years, providing an interesting insight into the internal morphology of the species Asteroceras. All these factors put this ammonite in a top bracket of discoveries of type.
Revitalising these fascinating, extinct marine animals phragmocone (exoskeleton-shell) and presenting them in a dramatic way, makes them perfect for collectors or interior designers. 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.
