A late Pleistocene human footprint from the Pilauco archaeological site, northern Patagonia, Chile - Fig 1

A) Location of archeo-palaeontological sites in southern South America dated around 12.500¹⁴C yr BP, including the Pilauco site (black star): 1) Pilauco, Osorno, Chile 2) Monte Verde, Chile. B) Detailed location of the Pilauco site next to the actual Damas River, at Villa Los Notros, Pilauco, street address: Río Cachapoal #159, Osorno. C) Schematic stratigraphy of the Pilauco site (modified from Pino et al., 2013). PB-1: Lapilli tuff; PB-2: Lapilli tuff with abundant volcanic ash matrix; PB-3: Lapilli tuff with medium sand matrix; PB-4: Volcanic ash; PB-5: Terrigenous coarse sand with scattered angular pebbles; PB-6: Gravel composed by clasts ranging from 1 to 15 cm in diameter; PB-7: Highly fossiliferous peat (indicated by a white bone drawing) with very dark brown matrix (10Y 3/1) including isolated and poorly selected gravel clasts up to 7 cm of Andean source. This layer is overlaying PB-2 and PB-6 by erosive unconformities; PB-8: Sandy peat (2.5Y 4/2), slightly more brown in color than PB-7. PB-9: Non-fossiliferous black peat (2.5Y 2/0). Both, PB-7 and PB-8 share a lateral facies change toward the South with an interfingering of gravel and sand layers.
