I still continue to find this particular type of fossil. But can't quite seem to take a description of the find beyond (probable fish element).
Found from the Peterborough Member (Callovian, Middle Jurassic) of the Oxford Clay. more commonly known as the Lower Oxford Clay.
Also just to say other identical finds to this one seem to have the same appearance, shape, size and colouration. And are quite sporadic when found.
All suggestions welcome.
Scale bar is in millimetres.
