FIG. 6 in Extending the tooth mesowear method to extinct and extant equids

FIG. 6. — Hierarchical cluster diagrams based on the mesowear variables %high (percent high occlusal relief), %sharp (percent sharp cusps) and %blunt (percent blunt cusps) of the isolated tooth positions P2, P3, P4, M1, M2 and M3, the 3-tooth model P4+M2+M3, the 4-tooth model P4-M3 and the 5-tooth model P3-M3. Clusters based on a set of 27 "typical" recent comparison taxa after Fortelius & Solounias (2000); A-D, Hippotherium primigenium Meyer, 1829; A, from the Dinotheriensande (all localities); B, Eppelsheim; C, Esselborn; D, Westhofen; E, Equus burchelli Gray 1824 (ebN) from Sudan, Kenya and Tanzania; F, Equus burchelli (ebS) from Botswana, Namibia and Angola. For abbreviations see Table 1; upper case, browser; lower case, grazer; mixed case (capital first), mixed-feeder; mixed case (lower first), fossil species; NED, normalised Euclidean distance.
