The Geosciences Collection is valuable from a scientific as well as from a historical view and provides research opportunities in a large number of different fields and is also actively researching. Our research is mainly based on material of the collection, including fossils, rocks, minerals as well as shells of modern molluscs. The approach to the individual areas of expertise (geology, palaeontology and zoology) is principally different and thus a broad link within the faculty of Geosciences of the University of Bremen is needed, as well as a lively international research exchange with other museums and universities. A transdisziplinary mode to think and work is essential, since cultural and history of science aspects are included, for example in our provenance research. Additionally, research on preparation and techniques as well as aspects of collection management is covered.

Working Area

A number of cooperation is realised with adjacent disciplines, but our working-group is focussing its own research on the reconstruction of ancient environments and the interaction of organisms with their environment and furthermore with environmental change. Thus our research questions in the field of invertebrate and micropalaeontology is leaded by processes. Among our core area palaeontology Cretaceous biota and ammonoids are particularly in the focus. Another balance point is palaeobiology of diverse groups of organisms (ammonites, foraminifera, bivalves).


Our research needs a number of preparation and processing methods of the fields of geology and palaeontology. The equipment used includes handheld gamma ray devices, a studio for the preparation of fossils and a chemical laboratory to conserve rocks and fossils and to process micropalaeontological samples. We apply various photography techniques for documentation and publication. Additionally, we establish 3D modes by photogrammetry for documentation, and also for topographic analysis of macrofossils and use multivariate statistical analyses for the reconstruction of fossil communities.
