• A study has found new global records of abundant ghost fossils from three Jurassic and Cretaceous warming events (94, 120 and 183 million years ago)

  • The fossils are microscopic imprints, or “ghosts”, of single-celled plankton, called coccolithophores, that lived in the seas millions of years ago.

  • Study suggests plankton have been badly affected by climate change and ocean acidification
