Geology and palaeontology of the Rott fossil lagerstätteThe late Oligocene fossil site of Rott near Bonn is one of the famous German oil shale localities. The finely laminated lake sediments produce extraordinarily well-preserved plant, invertebrate and vertebrate fossils. Current research concentrates on microfacies, and Ar-Ar dating.

Vertebrates, biostratigraphy and palaeoecology of the Hambach mineFrom the continental strata exposed at Hambach, the world´s deepest open cast lignite mine, rich vertebrate associations have been excavated during the last years. The sites cover a time span from the middle Miocene to the early Pleistocene and contain mainly isolated bones and teeth of fish, amphibians, reptiles, and mammals. They help to reconstruct the history and palaeoecology of the world´s largest and longest-lasting delta system.

Mammals from the Neuwied basin, the Westerwald, and the Vogelsberg areaIn this project mammalian remains of three volcanic crater deposits are studied: the late Oligocene Enspel lagerstätte, the middle Miocene Homberg locality, and the late Pleistocene Wannen site. Focus of research is on biostratigraphic ages and paleoenvironments.

Incisor enamel microstructure of beaversDuring Tertiary and Pleistocene times, different genera and species of beavers populated the northern hemisphere. Although during the Tertiary and Pleistocene different genera and species of beavers are very common in fluvio-lacustrine sediments, castorid phylogeny is not well understood. The investigation of the incisor enamel microstructure is a powerful tool for reconstructing the evolution of the northern hemisphere´s biggest rodents.
