Short summary
Our culture experiments on modern Coccolithophores find that physiology regulates shifts in the geometry of their carbonate shells (coccospheres) between growth phases. This provides a tool to access growth information in modern and past populations. Directly comparing modern species with fossil coccospheres derives a new proxy for investigating the physiology that underpins phytoplankton responses to environmental change through geological time.
