The fate of a turtle

Many, many stories to be told. Recently I read a post on Ken Johnston's blog about a gentleman who has been studying these kind of stones for the last 50 years!

A couple of weeks ago, I picked this stone, attracted by the unusual shape and thinking that the rounded part had been faceted. On closer examination, it appeared to be a fossil. Then a fossil that looked like a turtle. Then a turtle being eaten by an animal. Then a smaller animal on top of the bigger animal. Then maybe some kind of whale or big fish on the other side...?
How amazing is that?
