1 m thick and the ectexine was thicker than the endexine
Endexine was reticulated, and ectexine was intectate.
According to Saenz de Rivas (1976), exine is composed by endexine, which is an internal reticulated layer, and by an external gemmate layer called ectexine that shows a striate without tectum.

The exine has a very thin endexine layer, and a fibrilar intine with numerous invaginations coated by the plasmalemma can be observed.
The endexine is the inner part of the exine, is located above the foot layer and has a different electron density than the foot layer.
