摘要	Molar enamel thickness and distribution pattern inform on the functional and dietary adaptation of extant and fossil primates. However, no systematic analysis of enamel thickness has been conducted onLufengpithecus, a large-bodied fossil hominoid that lived in Southwest China during the late Miocene. In this study, we quantify two-dimensional (2D) enamel thickness and distribution of 68 lightly worn molars ofLufengpithecus(L.)lufengensisusing micro-CT scanning data and compare it with modern humans, extant great apes, and fossil hominoids. The results indicateL. lufengensishas relatively thick enamel. It is slightly thicker than extantPongoand comparable to some thick-enamel fossil pongines, but thinner than modern humans and most fossil hominins. The enamel distribution ofL. lufengensisis distinctively unbalanced with relatively more enamel deposited on the cuspal region than the basal region in the molar crown, different from that found in modern humans and extant great apes. Concerning its palaeoecological and functional adaptations, we suggest that the features of thick-enamel and unbalanced distribution pattern inL. lufengensisis related to its adaptation to tough food and broader diets in a seasonal subtropical habitat.
