Answered for now - Fossil found near Carsington Water

Hello,

 

We would like some help identifying this fossil that we found near Carsington Water in Derbyshire.

 

There are two thicker marks in the vertical direction with finer lines radiating outwards which extend aproximately one third of the way around the back of the piece.

It looks to be of plant origin to me but frankley, I have no idea.SDC11832.JPGSDC11831.JPG My daughter thinks it looks like the mid section of an Illaenus TrilobiteSDC11833.JPGSDC11834.JPG Thanks for your help,

    If we are talking Carboniferous, then, whatever it is (trilobite or not), it is not a Illaenus. Only trilobites belonging to Proetida survived into the Carboniferous. If it is a Carboniferous trilobite then the number of thorax-segments indicates that it belongs to Aulacopleuroidea.

     

    You could try to contact Robert Owens of the National Museum Cardiff (see http://www.museumwales.ac.uk/en/189/) who is researching carboniferous trilobites in Britain.

    Hi there,

     

    It doesn't look like a trilobite to me. The pattern doesn't look quite right for it and I think the shape of the block overall and the markings are related, rather than being separate. I think fossil plant sounds more likely to me, but I will try and find out more from the experts when I'm back at the museum in the new year.
