Assessing paleotemperature and seasonality during the Early Eocene climatic optimum (EECO) in the Belgian basin by means of fish otolith stable O and C isotopes

The Paleogene greenhouse world comprises variable paleoclimate conditions providing an indispensable deep-time perspective for the possible effects of human-induced climate change. In this paper, paleotemperature data of the Early Eocene Climatic Optimum (EECO) from the mid-latitude marginal marine Belgian Basin are discussed. They are derived from fish otolith d 18 O compositions of four non-migratory species belonging to the families Congridae and Ophidiidae. Otoliths from several levels and localities within the middle to late Ypresian were selected. After manual polishing, bulk and increme... Mehr ...
