Definition of "palynological"

Palynological fossils comprising algal and fungal bodies, bryophytic and pteridophytic spores, gymnospermic and angiospermic pollen grains and a host of other organisms are more reliable and precise in determining age and reconstructing palaeoenvironment for the abundance almost in all the varied conditions of deposition.
