Often when fossil hunting on Charmouth beach you come across ammonites which have been damaged by exposure to the elements for too long. The aim is to save them before this happens, otherwise their 195 million year journey is forgotten and they are turned to dust.
However, very occasionally, the beach does help a little. Making pieces like this possible. Another day or two in the active beach system and the sand and waves would have destroyed it.
One side of this Xipheroceras ammonite was eroded but the other side was safely still encased in it's limestone matrix. I removed this by using iron powder air abrasive.
When a light is shone behind it, it's beautiful red and orange tones shine though, coloured by the calcite and minerals that have replaced the ammonite over time :)
If you stay watching for long enough you will see a sped up video of the abrasive preparation of this piece.
