文摘

•: Sr, C, O isotopic data of well-preserved Campanian chalk from eastern Poland is shown.
•: Early-diagenetic calcite cementation did not alter the bulk isotopic composition.
•: δ¹³C and paleotemperature drop during the Campanian.
•: Belemnites were probably nectobenthic organisms.
•: Vital effects of up to 2‰ were recorded in δ¹³C and δ¹⁸O of benthic foraminifera.
