	abstract = {<p>ABSTRACT Stable oxygen isotope values of inoceramid marine bivalve shells recovered from Bentiaba, Angola, are utilised as a proxy for paleotemperatures during the Late Cretaceous development of the African margin of the South Atlantic Ocean. The δ18O values derived from inoceramids show a long-term increase from {\textendash}3.2{\textperthousand} in the Late Turonian to values between {\textendash}0.8 and {\textendash}1.8{\textperthousand} in the Late Campanian. Assuming a constant oceanic δ18O value, an \~{}2{\textperthousand} increase may reflect cooling of the shallow marine environment at Bentiaba by approximately 10{\textdegree}. Bentiaba values are offset by about +1{\textperthousand} from published records for bathyal Inoceramus at Walvis Ridge. This offset in δ18O values suggests a temperature difference of \~{}5{\textdegree} between coastal and deeper water offshore Angola. Cooler temperatures implied by the δ18O curve at Bentiaba coincide with the stratigraphic distribution of diverse marine amniotes, including mosasaurs, at Bentiaba.</p>
