see below photograph. This one was found in a stream near Boxworth, at a point where the formation changes from Kimmeridge Clay to Ampthill clay but I’m picking over the shingle exposed by the stream.
I tend to find small ammonites fragment, this one is the largest I’ve found here. I’m thinking about sending it to be prepared, not sure if the centre will be intact.
Interesting to know that the initial fragment is from an ammonite, must have been extremely large!
thanks for the responses
