Middle Burdigalian stratigraphy, age model, and U^K'₃₇-based SSTs. Correlation of the regional (sub)stages is based on Piller et al. (2007), Pippèrr et al. (2007), and Hilgen et al. (2012). For details on the age model and stratigraphic error margins see text and Tables 1 and 2. Solid dark grey lines highlight the two identified EOC cold snaps; stippled line marks the upper limit of 28.2 °C for SST reconstruction from alkenones. The number “6” in OS column refers to the number of samples in this very narrow time interval represented by Ottnang-Schanze. See Fig. 1 for abbreviations of individual localities. C.P. = Central Paratethys.
