The morphology of the enamel–dentine junction in Neanderthal molars: Gross morphology, non-metric traits, and temporal trends

摘要: This study explores the morphological differences between enamel–dentine junction (EDJ) of maxillary and mandibular molars Neanderthals (n = 150) recent modern humans 106), an earlier Neanderthal sample (consisting Pre-Eemian Eemian dating to before 115 ka) a later Post-Eemian after ka). The EDJ was visualised by segmenting microtomographic scans each molar. A geometric morphometric methodology compared positioning dentine horns, shape marginal ridge cervix. We also examined manifestation non-metric traits at including crista obliqua, cusp 5, post-paracone tubercle. Furthermore, we report on additional features centrally placed horn tips twinned horns. Our results indicate that morphology can discriminate with high degree reliability every molar position, samples except for M3 in space. cervix isolation humans, form space, is effective discriminating samples, M2/M2 In addition demonstrating taxonomic valence EDJ, our analysis reveals unique manifestations dental expanded levels trait variation have implications definitions scoring.
