Enamel thickness cartographies of the Atapuerca-SH upper M1 (AT-2071) compared with those of H. antecessor (ATD6-103) from Atapuerca-Gran Dolina, Neanderthal and modern human.

Topographic thickness variation is rendered by a pseudo-color scale ranging from thinner dark-blue to thicker red. NEA = Neanderthal (La Quina-H18) and MH = modern human of European origin (O = occlusal, L = lingual). Scale bar = 1.75 for all specimens. (When needed specimens have been mirrored to the left to match the SH specimen).
