• A study 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
  • The study suggests that planktons were severely affected by climate change and ocean acidification
