Isotope geochemical data (δ13C, δ18O and δ11B), mean shell sizes (log2 mm) of brachiopod and bivalve assemblages5, standardized species richness (Shareholder Quorum Subsampling [SQS] diversity) and abundance (absolute number) of specimens in samples (standardized by sample weight) of the Barranco de la Cañada succession. Selected biodiversity metrics are based on the taxonomic composition of faunal samples54.
