High‐Resolution Temperature Variability During Eocene Greenhouse in Messel

High‐resolution continental temperature records from geological archives are crucial in order to evaluate temperature dynamics under fundamentally different climate conditions than today. Particularly the warm early to middle Eocene (∼56–40 million years ago) has become the focus of paleoclimate studies with the intention of quantifying temperatures under high atmospheric carbon dioxide (pCO2) levels. Here we present a ∼430 thousand‐year high‐resolution continental temperature record, reconstructed from terrestrial biomarkers preserved in the maar sediments of the UNESCO World Heritage Site “Messel Fossil Pit,” Germany during the earliest middle Eocene of Central Europe (∼47.7–47.2 million years ago).
