DATA-SPECIFIC INFORMATION FOR: Supplementary Data 1. Number of variables: 14 2. Number of cases/rows: 49 3. Variable List: Name: Species name, Mantle length (mm): reported mantle lengths of squid and cuttlefish (mm), Type of biogenic carbonate: the biogenic carbonate used for isotope analyses, d18O range (ä): a range of stable oxygen isotope values in biogenic carbonates (per mille), d18O mean (ä): a mean of stable oxygen isotope values in biogenic carbonates (per mille), d13C range (ä): a range of stable carbon isotope values in biogenic carbonates (per mille), d13C mean (ä): a mean of stable carbon isotope values in biogenic carbonates (per mille), Temperature (¡C): experienced temperatures of cephalopod species that were either reported in the literature or estimated from d18O mean values. Cresp: predicted proportion of carbon in the biogenic carbonate derived from metabolic sources. Reference: carbonate isotope values: the reference of stable carbon isotope values in biogenic carbonates. d13CDIC: stable carbon isotope values of dissolved inorganic carbon in seawater (per mille) that is used to calculate Cresp values. Reference: d13CDIC: the reference of stable carbon isotope values of dissolved inorganic carbon in seawater. d13Cdiet: stable carbon isotope values of diet (per mille) that is used to calculate Cresp values. Reference: d13Cdiet: the reference of stable carbon isotope values of diet. 4. References of all used data in the dataset.
