Michael,

Thanks for the images. I just wondered if you could kindly clarify what we are looking at here. Are the lighter brown smudges extruded stomach contents, or the animal itself? I must admit that I am somewhat confused by the images.

It seems to me that a definitive ammonite fossil displaying soft-bodied preservation at the head is pretty much a holy grail amongst invertebrate palaeontologists. Finally defining the structure of the animal would answer so many questions (though doubtless would raise many more!).

Please help!
