Micropalaeontology and ocean evolution

The breakup of Pangea gave birth to new oceans. We trace their history by analysing the sediments composed of planktonic micro-organisms. We build biochronological time scales based on the appearance and extinction of radiolarian and foraminifer species. These time scales allow us to date the opening and closing of ancient oceans and the formation of mountain ranges.
