These ammonites are preserved in nodules from the ‘Green Ammonite Beds’, which sounds fantastic. But a word of warning: they are extremely difficult to clean or prepare! A specimen like this could take several hours of highly skilled time to expose. Most ammonites from this bed are preserved as body chambers – the long, last outer whorl of the shell with the hollow section having been crushed.
