“…Second are lowland riverine or lacustrine plains, characterized by open and semi-open vegetation, as at the Bulbula River sites (Lesur et al, 2016), Laas Geel rockshelter (Gutherz et al, 2014), the Rifle Range and Guli Waabayo inselberg sites (Jones et al, 2018;Jones and Brandt, 2022), the Kibish Formation (Assefa et al, 2008;Trapani, 2008), Victoria Basin fossil beds (Faith et al, 2015;Tryon et al, 2012), and Mumba Rockshelter (Mehlman, 1989). A third group of sites are found in higher-elevation grasslands, as in the Athi-Kapiti Plains of Kenya at the Lukenya Hill sites (GvJm19, GvJm22, GvJm46, and GvJm62) (Marean, 1992b), and in the Serengeti Plains of Tanzania at Nasera Rockshelter, Gol Kopjes, Loiyangalani, and the Ndutu Beds at Olduvai Gorge (Eren et al, 2014;Gifford-Gonzalez, 2011;Masele, 2020;Mehlman, 1989). Finally, a fourth group of sites are located in semi-wooded uplands, as at Kisese II Rockshelter in the Irangi Hills and at Magubike and Mlambalasi Rockshelters in the Iringa Highlands (Collins and Willoughby, 2010;Masele, 2017;Masele and Willoughby, 2021;Tryon et al, 2019).…”
