The Natufians of the southern Levant (15,000 -11,500 cal BP) underwent pronounced socioeconomic changes associated with the onset of sedentism and the shift from a foraging to farming lifestyle. Excavations at the 12,000-year-old Natufian cave site, Hilazon Tachtit (Israel), have revealed a grave that provides a rare opportunity to investigate the ideological shifts that must have accompanied these socioeconomic changes. The grave was constructed and specifically arranged for a petite, elderly, and disabled woman, who was accompanied by exceptional grave offerings. The grave goods comprised 50 complete tortoise shells and select body-parts of a wild boar, an eagle, a cow, a leopard, and two martens, as well as a complete human foot. The interment rituals and the method used to construct and seal the grave suggest that this is the burial of a shaman, one of the earliest known from the archaeological record. Several attributes of this burial later become central in the spiritual arena of human cultures worldwide.Hilazon Tachtit Cave ͉ Natufian ͉ mortuary practices ͉ origins of agriculture
We present here a newly developed software package named Artifact GeoMorph Toolbox 3-D (AGMT3-D). It is intended to provide archaeologists with a simple and easy-to-use tool for performing 3-D landmarks-based geometric morphometric shape analysis on 3-D digital models of archaeological artifacts. It requires no prior knowledge of programming or proficiency in statistics. AGMT3-D consists of a data-acquisition procedure for automatically positioning 3-D models in space and fitting them with grids of 3-D semi-landmarks. It also provides a number of analytical tools and procedures that allow the processing and statistical analysis of the data, including generalized Procrustes analysis, principal component analysis, a warp tool, automatic calculation of shape variabilities and statistical tests. It provides an output of quantitative, objective and reproducible results in numerical, textual and graphic formats. These can be used to answer archaeologically significant questions relating to morphologies and morphological variabilities in artifact assemblages. Following the presentation of the software and its functions, we apply it to a case study addressing the effects of different types of raw material on the morphologies and morphological variabilities present in an experimentally produced Acheulian handaxe assemblage. The results show that there are statistically significant differences between the mean shapes and shape variabilities of handaxes produced on flint and those produced on basalt. With AGMT3-D, users can analyze artifact assemblages and address questions that are deducible from the morphologies and morphological variabilities of material culture assemblages. These questions can relate to issues of, among others, relative chronology, cultural affinities, tool function and production technology. AGMT3-D is aimed at making 3-D landmarks-based geometric morphometric shape analysis more accessible to archaeologists, in the hope that this method will become a tool commonly used by archaeologists.
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.
