Paleobotany

Research interests

Approach: Fossil plants as living organisms in deep time — morphology, anatomy, biological affinity, ecology, fossilization

  • Mesozoic paleobotany
  • The conifer Araucaria, past and present
  • Conifer seed cone architecture
  • Jurassic and Tertiary woods
  • Eocene Nypa mangroves
  • Tertiary fruits and seeds of the Lower Rhine Embayment, Germany
  • Fossil water lilies
  • Actuopaleobotany of recent carpological deposits
  • Fossilization of plants, especially wood silicification and the preservation of leaf compressions
  • Where molecular biology meets paleobotany: the earliest stages of preservation in leaves
