Global record of “ghost” nannofossils reveals plankton resilience to high CO 2 and warming
Predictions of how marine calcifying organisms will respond to climate change rely heavily on the fossil record of nannoplankton. Declines in calcium carbonate (CaCO 3 ) and nannofossil abundance through several past global warming events have been interpreted as biocalcification crises caused by oc...

Predictions of how marine calcifying organisms will respond to climate change rely heavily on the fossil record of nannoplankton.
