Abteilung Geobiologie
Welcome to the Department of Geobiology!
Geological and biological processes are often directly related, and have greatly influenced the biodiversity and shape of our planet. The Geobiology Group studies the evolution of organisms and the interactions between the biosphere and the geosphere, in the present and throughout Earth's history since life originated at least 3.5 billion years ago. In addition to multicellular animals and plants, which are in the focus of classical paleontology, we are also interested in microorganisms that once made our planet habitable to animals and higher plants, and which have dominated the biosphere for over 80% of Earth's history. We want to know what these microorganisms are, understand their metabolic and survival strategies, and gain insight into how they have had, and continue to make, a lasting impact on Earth’s element cycles. Geobiology is a highly interdisciplinary science. Our research employs state-of-the-art methods ranging from paleontology, geochemistry, microbiology, zoology, botany, and molecular genetics. Geobiological research generates knowledge that can address real world problems, for example the extraction and recycling of industrial raw materials and the rehabilitation of contaminated ecosystems. Geobiology also provides important fundamental knowledge for managing ecosystems, responding and adapting to the challenges of today’s global climate change, and also to understanding how extra-terrestrial geological and potential biological systems may have evolved.

New pieces of the puzzle discovered to reconstruct earliest life
Congratulations to Manuel Reinhardt, part of the Geobiology Team, with new findings about a 3.4 - billion-year-old ecosystem.

The researchers analysed well-preserved particles of carbonaceous matter – the altered remains of living organisms – and the corresponding rock layers from samples of the Barberton greenstone belt, a mountain range in South Africa whose rocks are among the oldest on the Earth's surface. The scientists combined macro and micro analyses to clearly identify original biological traces and distinguish them from later contamination. They identified geochemical "fingerprints" of various microorganisms, including those that must have used sunlight for energy, metabolised sulphate and probably also produced methane.

Congratulations to Eric Runge for receiving the renowned Paul-Ramdohr Award on September in Vienna for his presentation at GeoMinKöln 2022. Eric compared the characteristics of synthetic and biogenic Fe-minerals with minerals in modern and ancient hydrothermal sulfide deposits. This will improve the understanding of the formation and preservation of biosignatures in hydrothermal environments and thus contribute to the reconstruction of microbial life.
