Middle Campanian (Late Cretaceous) sea-level rise; microfossil record of bathymetric changes
A Middle Campanian (Late Cretaceous) eustatic sea-level rise recorded in the Belgorod succession (Russia; eastern North European Basin) was analyzed. The succession, dated for the Gavelinella annae and Globorotalites emdyensis foraminiferal zones (corresponding to the ‘Inoceramus’ azerbaydjanensis–‘...
