PCA biplots of from comparison of Nubian Levallois points and other Levallois Points (left), and Nubian Levallois cores and other Levallois cores (right): (a, d) Nubian Levallois points and cores from Shukbah fall within variability observed across the wider body of Levallois points and cores; (b, e) the Shukbah point and core assemblage show considerable comparability to other late Middle Palaeolithic (LMP) datasets (dated to MIS 4/3 and/or associated with Neanderthals), including Nubian Levallois specimens which fall within the range of morphological variability observed. (c, f) the Shukbah point and core assemblage, including Nubian Levallois points and cores, show considerable comparability to other Late Pleistocene (MIS 5–3) Middle Palaeolithic Levallois Points and Cores, whereas Nubian Levallois points and cores from other Late Pleistocene Middle Palaeolithic sites typically exhibit distinct differences in artefact morphology.
