Rzger:

Kindly provide scale and indicate associated reworked palynoformphs including the actual age of the younger horizon.

Dear Kak Rezgar,

It is almost impossible to decide, at least you have to know from where you got the sample, what type of rocks??

Dear Syed and Varoujan,

The scale is x100 and it is from Northern Iraq and I think it is from Carboniferous ? horizons.

Regards,

Dear Rzger,

I think it is spore named  insculptospora maxima sp.nov

Please have a look to the following article: 

Climate-controlled palynofacies and miospore stratigraphy of the Jauf Formation, Lower Devonian, northern Saudi Arabia

Abdalla:

Specimen documented by Rzger does not match the species: Insculptospora maxima . Have a look at the documented form in this link:

Dear Rzger,

I am pretty sure it is not Insculptospora maxima. Looks like a long-ranging retusoid form. What is the amb size and the ornamentation type?

Regards,

Pierre
