Fig. 3: Seasonal coral proxy records.
From: Mid-Miocene warmth pushed fossil coral calcification to physiological limits in high-latitude reefs
a Early Langhian/early Badenian (U4). b Late Langhian/middle Badenian (Dras). c Early Serravallian/late Badenian (Poetz). Thin gray lines in the density and element/Ca records depict measured value resolution, thick black lines 5-point running averages. Circle symbols in the stable isotope records indicate measured data points. Blue vertical lines define years. Shaded area in (a) highlights the growth anomaly detected in coral U4 (Supplementary Fig. 2). The vertical red line in (a) indicates the timing of the inferred bleaching event and the horizontal green line in the corresponding Sr/Ca record mean values for the data prior to and after the stress event. The vertical red line in (b) marks a growth hiatus that is recognizable in the X-ray image (Supplementary Fig. 1c). Note the inverted y-axes for density, δ18O and Sr/Ca.
