The group has involved specialists in morphology and anatomy and experts in botanical research as electron microscopy, pollen studies, chromosomes, chemistry, and DNA analysis.

It is well known for its pollen studies.

Hall, V.A. and Bunting, L. (2000) Tephra-dated pollen studies of medieval landscapes in the north of Ireland.

The pollen studies are supported by both the fish and plant megafossils that are found in the formation, both of which support an Oligocene age.

Even though many spruces currently grow in that vicinity, recent pollen studies show that spruce forests came surprisingly late to that stretch of land.

This Turkish site is of Miocene age and is well known for its pollen studies.

Erdtman systematically studied pollen morphology and developed the method of acetolysis in pollen studies.

Other recently reported pollen studies in the Massif Central of France, combined with an analysis of the mineral content of lake deposits there, have likewise suggested rapid climatic fluctuations in the Eemian.

The demise of tree species is clear in pollen studies, and there is a lot of evidence for greatly accelerated soil erosion, including increased sediment deposition in deltas with lots of soil-derived organic debris.
