a PC1arid-PC2arid plot and PC1arid scores. The early Eocene low magnetisation zone (EELMZ) was excluded because of its anomalous magnetic mineral assemblage (see Supplementary information). b Contessa Road stable carbon isotope (δ13C) record presented in terms of mean (black) ± 2 standard errors (SE) (grey shaded bands)19. Hyperthermals (Palaeocene-Eocene Thermal Maximum (PETM), Eocene Thermal Maximum (ETM) 2 and ETM 3), smaller carbon cycle perturbations, the early Eocene terrigenous zone (EETZ), and the early Eocene low magnetisation zone (EELMZ) are indicated with orange, purple, green and yellow bands, respectively.
