Dear Abelardo,
Many thanks for your time and interest.
Best wishes,

It is some time since I have looked at Devonian material. Is it a kind of Nikitinsporites? Or must that have small bifurcate tips to the spines? If you cannot get an answer online you should write a short question to the C.I.M.P. Newsletter and that way you will get all Palaeozoic palynologists to see you specimen.

Dear Duncan,
Many thanks for your interest. Nikitisporites is kind of Megaspoers, I think. This specimen is in range of miospores on the basis of measurements. I sent this photo to many Palaeozoic palynologist, but finally I drew a blank at all of them. Your suggestion is a new chance to determine it!
