Fig. 1 Leaf epidermis and examples of epidermal phytoliths.(A) Nothofagus leaf and epidermis. Leaf epidermis and examples of epidermal phytoliths.(A) Nothofagus leaf and epidermis. (B to E) Fossil phytoliths from Patagonia. (F to I) Modern soil phytoliths from Costa Rica. Regan E. Dunn et al. Science 2015;347: Published by AAAS

Fig. 2 Modern soil phytolith morphology and LAI.(A) Hemispherical photographs from Costa Rica illustrating LAI values. Modern soil phytolith morphology and LAI.(A) Hemispherical photographs from Costa Rica illustrating LAI values. (B) Linear regressions for mean PUI and LAI (rLAI = × PUI – 17.31); and (C) mean Phytolith Area (PA) and LAI (rLAI = × PA ). (D) Plot of simulated versus measured values of LAI. Simulated values are derived from Eq. 1. Regan E. Dunn et al. Science 2015;347: Published by AAAS

4 Fig. 3 Middle Cenozoic rLAI and comparisons to climate and biotic records.(A) rLAI reconstruction with 95% confidence intervals. Middle Cenozoic rLAI and comparisons to climate and biotic records.(A) rLAI reconstruction with 95% confidence intervals. Shown are raw values (open circles) and binned values by age or geologic unit (red diamonds) (table S4). (B) Foraminiferal δ18O records for sea surface (red) (21) and deep sea temperature (blue) (8). (C) MAT (blue), MAP (green), and dry-season precipitation (orange) estimates from megafloras (27, 33), with corrected ages (table S5). Length of the solid bars indicate age uncertainty. Yellow boxes are MAP estimates from paleosols (34). (D) Proportion hypsodont+hypselodont taxa of notoungulates, with 95% confidence intervals (table S6). Regan E. Dunn et al.
