Benjamin Sames

Research Interests/Expertise:

  • Micropaleontology of Mesozoic and Cenozoic Ostracoda (and Charophyta) with focus on Mesozoic non-marine deposits (Upper Jurassic–Lower Cretaceous) of the world
  • Integrated Stratigraphy (incl. biostratigraphy, chemostratigraphy, cyclostratigraphy) with focus on the Cretaceous
  • Fundamentals, principles and methods of the biostratigraphic application of (late) Mesozoic non-marine Ostracoda
  • Paleoclimatology and climate change, ocean-land interactons and its impact on life and the hydrological circle with focus on the Cretaceous
  • Cretaceous greenhouse climate, Mesozoic climate shifts and climate extremes
  • Mesozoic evolution of non-marine/terrestrial habitats
  • Ostracod biostratigraphy, palaeoecology, palaeobiogeography, phylogeny
  • Palaobiology and application of ostracod reproductive and dispersal mechanisms
  • Origin and early evolution of non-marine ostracods
  • Taxonomy and application of Late Jurassic-Cretaceous Charophyta
  • Theoretical, practical and applied taxonomy
