   • 1971 September, Calcutta Review, page 52:

     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.

   • 2017 January 4, Susannah Lydon, “Bring me sunshine in your spores”, in The Guardian‎:

     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.
