Abstract:
Previous investigation demonstrated the strength of using a multi-taxa approach (combining records from M. campechiensis shells and A. felis otoliths) to reconstruct conditions in an estuarine environment as is the case here. Comparing δ18O records from both species allowed us to reconstruct relative cool versus warm and wet versus dry conditions. Eight shells and four otoliths representing the entire stratigraphic extent of the VM were selected for isotopic analysis and microsampled at submonthly resolution. The δ18O time series from the otoliths and shells indicated the winters and summers in the beginning of the VM were relatively warm and wet (similar to today). Winter temperatures cooled by 1-2°C in the mid VM, and summers were relatively dry. The late VM had winter temperatures similar to today and dry summers. Our climate reconstructions based on isotopic data are in good agreement with archaeological observations and with the cool and dry conditions documented in Europe.
