Short summary

The ANDRILL SMS site provides the first Middle Miocene Antarctic fungal record. The CREST plant-based paleoclimate reconstructions confirm an intensification of the hydrological cycle during the MCO, with the Ross Sea region reconstructed 279 % wetter than modern conditions and a maximum mean annual temperature of 10.3 °C for the warmest intervals of the MCO. The plant-based reconstructions indicate a temperate, no dry season with a warm summer (Cfb) Köppen–Geiger climate classification.
