Monitoring mineralogical and porosity transformations in modern Hebron ceramics caused by salt whitening agent using non-invasive methods
Micro-CT highlights the effects of adding sodium chloride salt on ceramic porosity and the redistribution of pores. • SWIR Hyperspectral Imaging allows the observation of phase changes resulting from variations in ceramic firing temperatures. • SWIR Hyperspectral Imaging presents great potential for determining firing temperatures using non-destructive tools. A field investigation conducted among potters in Hebron (Palestinian Territories) reveal…
Exploring Hypotheses on Early Holocene Caspian Seafaring Through Personal Ornaments: A Study of Changing Styles and Symbols in Western Central Asia
This article studies the discoid Didacna sp. shell beads discovered at Kaylu, a Middle Holocene burial site located in Southern Turkmenistan. Microscopic, morphometric, spectrometric, and SEM analyses were carried out on the material to identify how the beads were manufactured and used. New radiocarbon dating and bioanthropological data to age and sex the two skeletons discovered in the burials are provided. A regional synthesis shows that person…
Technological analysis and experimental reproduction of the techniques of perforation of quartz beads from the Ceramic period in the Antilles
Personal ornaments are a very specific kind of material production in human societies and are particularly valuable artifacts for the archaeologist seeking to understand past societies. In the Caribbean, Early Ceramic Age sites have yielded a highly diverse production both in terms of raw materials and typology. In recent years they have been the subject of renewed interest, mainly based on the diversity and provenance of raw materials, and on ty…

Investigating Past and Present Carpometacarpus Morphology in Mimidae: A Multi-Methods Approach to Evidence from the Guadeloupe Islands
Past bird communities are still under-studied in several Caribbean regions, including the Lesser Antilles. In order to improve our understanding of this area’s avifauna, we explore morphometrical variations of the carpometacarpus (CMC) within West Indies Mimidae species. We combine geometric morphometric (GMM) and conventional osteology focusing on characters of the entire or distal portion of the CMC. Morphological variation related to their phy…
A case of marked bilateral asymmetry in the sacral alae of the Neandertal specimen Regourdou 1 (Périgord, France)
OBJECTIVES: A marked asymmetry was previously reported in the sacral alae and S1-L5 facets orientation of the Neandertal individual Regourdou 1. Here, we provide a detailed description and quantification of the morphology and degree of asymmetry of this sacrum. MATERIAL AND METHODS: Regourdou 1 was compared to a modern human sample composed of 24 females and 17 males, and to other Neandertal individuals. Both traditional and geometric morphometri…
