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.

It also demonstrated that pollen prepared using standard palynological methods still retained a good UAC signal, meaning that thousands of previously studied pollen preparations, stored in museums and institutions worldwide, may be repurposed to tell us more about sunshine in the past.
