Pontosphaera multipora

I have seen a top for this species reported at around the base of NN 16. Is this based on the range of some sort of variant?

good question

good question - the name P. multipora seems to be used very broadly and I can well imagine thatthre are different forms with restricted ranges. In terms of taxonomy since Kamptner's type was from the Late Miocene there is no guarantee that the modern species is the same thing
