These images, taken at the light and scanning electrone microscopes (SEM) at the Microscopy Unit at Uppsala University, provide an insight into the microscopic world of ancient fossilized plant macrofossils and pollen and demonstrate the unique structures and textures of these ancient specimens.

The first images are light and SEM micrographs of plant macrofossils extracted from sediments of Hässeldala which are 11-14 thousand years old. These are followed by SEM photos of Pinus, Picea and Abies pollen from a few thousand years ago, which were obtianed from the Lago Piccolo di Avigliana core in the Italian Alps and from lakes in Norway and Sweden. Finally, the last micrograph is a light microscope photo of Picea pollen in sediments from lakes.
