The aim of this session is to bring together palaeobiologists, geochemists and modelers from different disciplines to promote a better understanding of the role and evolution of terrestrial ecosystems, their impact on the atmosphere, lithosphere and climate and vice versa (for example biogeochemical and hydrological cycles, continental weathering). We encourage workers from all disciplines analyzing the terrestrial (in)vertebrate and plant fossil record by means of palaeobiological or geochemical methods to present their results from the deep time (pre-quaternary) geological history, particularly covering periods of major environmental changes and biotic turnovers (mass extinctions).
