Prof. Dr. Jens Lehmann is responsible for the scientific handling of the research collection and for research about a wide choice of specimens and various geological time slices. Thus, a comprehensive networking with scientist from Germany and abroad is a matter of course. The transfer of scientific knowledge into the public is intimately connected, as demonstrated by numerous exhibition projects, including other European countries, and almost 100 public talks for the public. Interested layman might consult Prof. Lehmann to know more about their finds, in case they want to donate specimens to the collection and a far as for assistance for own scientific work. The Geosciences Collection is an active partner in the dialogue between research and society, “Citizen Science” is applied in all individual aspects. This commitment is also the reason for the cooperation with the Quelle & Meyer publishing house and in particular with “Fossilien. Journal für Erdgeschichte” – a journal for which he is an advisory scientist. The research focus of Prof. Lehmann is the reconstruction of the palaeoenvironment, diversity of organisms and ammonoids. These topics are addressed with special focus on the Mesozoic. He is also self dependent in acquiring third-party funds and is coordinating several scientific projects.

New publication by Jens Lehmann in October 2023: Special issue of the journal “FOSSILIEN”

Collecting fossils from erratic boulders derived by the glacial drift is the most family-friendly way to experience Earth history. Especially at the coasts, children can also find loose fossils in a relaxed way and almost everywhere, including the classics “devil’s fingers” and sea urchins in flintstone preservation. In addition, boulder fossils offer a unique chance to find evidence of almost the entire history of life since the Cambrian, as the ice-age glaciers sent us a colourful variety of different fossils from Scandinavia. This special issue covers the entire range of possible discoveries, from “once i a century finds” like the ancient, mysterious stump-footed Xenusion to Germany’s second-oldest bird fossil and the common sea urchin. Particularly beautiful specimens are illustrated; several views of the same piece make this special issue with its generous graphic design an aesthetic pleasure as well. about 80 p., throughout colour ill., 21 x 28 cm. Available since October 2023 at Humanitas.
