Hi Juan,

I think it's calcified fern spore. Fern spores from sediments and strata are usually yellow-brownish-dark, depending the degree of thermal modification. You may google "trilete spore" images and find a bunch very similar to yours.

Hi Juan.
Yes the shape (and even the size) reminds me at pollen.
Is it possible recristallization process on pollen?
Find you several of them with the same structures?
