Extended Data Fig. 8: Pollen diagrams for sample WM18-MRD-210 and diatom diagram for WM18-LHG-248.
From: Age and context of mid-Pliocene hominin cranium from Woranso-Mille, Ethiopia

a, Relative abundances of pollen taxa (percentage) in WM18-MRD-210 calculated using the total number of pollen grains and fern spores. The asterisk indicate ‘-type’. Numbers in brackets refer to the number of pollen grains. b, Relative abundance of arboreal pollen (AP; trees and shrubs), non-arboreal pollen (NAP; herbs and forbs) and non-classified habitus (NC) in WM18-MRD-210. Numbers in brackets refer to the number of pollen grains. aqua., aquatic. c, Distribution of diatoms in WN18-LGH 248 according their ecological affinity: coastal–marine (yellow) versus brackish lacustrine (blue) environments. Among the species with coastal–marine affinities, Coscinodiscus lineatus and Coscinodiscus excentricus are typically observed in the Indian Ocean and Mozambique Channel48,49. Numbers in brackets refer to the number of diatom samples.
