    I think the stratigraphic range is wrong for this species you have assign it to NJ3 zoned, based on Bown & Cooper 1998. However in that publication it range is give as NJ2a subzone restricted significantly older

    Thanks Kevin - you are of course quite right and I have now corrected this. Please do keep pointing out errors!
