Fig. 2: Contessa Road climate proxy and geochemical records.
From: Dry hydroclimates in the late Palaeocene-early Eocene hothouse world
a Stable carbon isotope (δ13C)19, b Ca and CaCO319, c Fe, d bulk-rock hard isothermal remanent magnetisation (HIRM-BR), and e bulk-rock saturation remanent magnetisation (Mrs-BR) records from Contessa Road (this study). δ13C and CaCO3 are presented in terms of mean (black) ± 2 standard errors (2SE) (shaded grey bands). 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. The arrow in (a) indicates the long-term δ13C decrease. Lithology is indicated at the bottom of the figure with reddish (pink) and whitish limestones (grey) and marls (red). Source data are provided as a Source Data file.
