Fig. 1: Fossil site location and stratigraphic position.

A Mean annual precipitation (MAP) along the Peruvian western Andean slopes, showing location of the Late Miocene fossil site (yellow filled star), Holocene pollen samples from Paracas Bay and the G-10 core (pentagon), and modern leaf herbarium samples (circles) used for recalibrating and validating MAP equations. B Simplified lithostratigraphic log for the Pisco sediments at the Aguada de Lomas Locality (AGL), indicating existing chronostratigraphic framework for the AGL, as well as stratigraphic position of studied pollen samples (solid circles), wood and leaf-bearing bed (leaf icon), and U-Pb dated ash layers (solid blue stars). c clay, s silt, ss sandstone, g gravel. C Panoramic view of the present-day landscape at the Aguada de Lomas Locality.
