Here, the authors elucidate the evolutionary origins of coccolithophores, identifying impressions of their calcium carbonate skeletons in ~241- million-year-old rocks. Their presence in the Triassic, alongside unrelated calcifying organisms, suggests a diversification of marine calcifying organisms after the end-Permian mass extinction.
