Expanded excavations at the rockshelter of Jebel Humeima (J412) in south-west Jordan provide the basis for re-evaluation of its Upper Palaeolithic lithic assemblage. Initially identified as Levantine Aurignacian, the sample is more closely aligned with the Early Ahmarian. The framework currently used for the Levantine Upper Palaeolithic, combined with spatial clustering of specific blank and tool types, is directly responsible for initial misidentification. This spatial clustering is thought to represent two distinct activity loci: early-stage core reduction and later-stage blade and tool production. This kind of technological and typological variability may also help account for some of the ambiguity within the current Upper Palaeolithic framework of the southern Levant.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
