Asteroceras Ammonite 81mm


Availability:In stock


British Asteroceras ammonite partial boulder-stone excellently conserved with hours of preparation work which has produced a unique and aesthetically pleasing natural freestanding display specimen of large size for the type. England's lost treasures brought back to life from the world famous Heritage coast of the Jurassic period. Discovered in the Black ven layers. The heritage coast a stretch of over ninety five miles of coastline containing fossil flora and fauna produces few specimens of this calibre. Read the fuller report below...

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 specie Asteroceras. All these factors put this ammonite in a top bracket of discoveries of type.

Revitalising these fascinating, extinct marine animals phragmacones (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 environment of Britain.
