Relating to the study of pollen and spores, especially in the context of geology and archaeology.
The palynological analysis revealed important information about the ancient environment.
Palynological → It is formed from "palynein" (from Greek, meaning to scatter) and "logia" (from Greek, meaning study). The word refers to the study of pollen and spores, which are scattered by plants.
Think of 'scattering' ('palynein') of pollen and 'study' ('logia') — that's why palynological means the study of pollen.
