The electronic registration of the fossil plant collections is a major current project in the department. The goal is to provide an efficient way of searching for specimens and working on particular groups of plants or fossil sites.

The work with the so-called "Polarfloren", described by Oswald Heer, Alfred G. Nathorst, and others, is in progress. Information on the fossil site, age, organ of the plant, state of preservation and taxonomic position of each specimen is given. So far, the registration of the Spitsbergen material, comprising about 4500 specimens and ranging in age from Paleocene to the Early Oligocene is completed.

A second large collection is from Scania in southern Sweden. The Rhaetian and Liassic strata (210-180 million years old) contain a large variety of fossil plants and are of paramount importance for understanding possible environmental and floristic changes at the Triassic/Jurassic boundary. The collection contains abouts 25 000 specimens, among them almost 100 type specimens, which have been subject of numerous taxonomic publications and revisions.
