Data for: Offsets in the early Danian recovery phase in carbon isotopes: evidence from the biometrics and phylogeny of the Cruciplacolithus lineage

Appendices 1 and 2 are biometric parameters (length, width, area, ellipticity) for early Danian coccoliths of Cruciplacolithus at the sections of Bidart and Elles. Appendix 3 is a Matlab script designed to draw density plots of such data. Appendix 4 is an example of how to organize the data for use in the script.
