Short summary

We analysed Miocene dinocyst taxa and organic particle assemblages along a distal–proximal transect in the North Sea Basin. Based on distal and shallow marine successions, we reconstruct depositional changes across the Miocene Climatic Optimum (MCO; ~16.9–14.7 Ma) and use dinocysts as palaeoclimate proxies. Additionally, we provide five GDGT-derived sea surface temperature data points that support our dinocyst-based climate interpretation.
