“…Famous examples of this third size-range of spread-out settlements (Figure 7) are Great Zimbabwe (Garlake, 1970;Pikirayi and Chirikure, 2011;Chirikure et al, 2016Chirikure et al, , 2017, Cahokia (Fowler, 1989;Kelly and Brown, 2014;Baires, 2015;Pauketat et al, 2015) and the European oppida of the late 1st millennium BCE (Collis, 1984;Sievers and Schönfelder, 2012;Moore et al, 2013;Poux, 2014). It turns out that some very rare example even range up to 40-70 sq km and perhaps larger (Figure 8) such as Gelonas-a Scythian gorodische (Shramko, 1987(Shramko, , 2012Murzin et al, 1999;Zöllner et al, 2008) and the vast area of Chaco Canyon (Vivian, 1970;Wills and Dorshow, 2012;Drake et al, 2014;Price et al, 2017) in the SW of North America. As yet no-formally agreed term is available to refer to this class of settlement though some are contentiously called urban or else rejected as urban, either periodically or at the same time.…”
