“…Global and regional palaeovegetation studies demonstrate that warm and dense forests were widely distributed in the middle Miocene (Wolfe, 1985;Utescher et al, 2011b;Pound et al, 2012). Palaeovegetation data support the presence of cool-temperate mixed forests in the high-northern latitudes (White et al, 1997), (Pound et al, 2012), warm-temperate mixed forests in mid-latitudes (Utescher et al, 2007b;Utescher et al, 2011b;Retallack, 2007), and even tundra and shrubs in Antarctica (Lewis et al, 2008).…”
