A 6th-8th c. wire-drawing iron plate with silver residue from a Vendel Period workshop in Old Uppsala, Sweden
Metal wire is in modern society manufactured by drawing metal rods through dies with conical holes of decreasing diameters, until the desired thickness is obtained. The history and origin of this technique remains unclear, although it was likely developed from earlier wire-making techniques such as strip-drawing and roll-drawing. Proper wire-drawing was an established technology in Europe during the High Middle Ages, and numerous draw-plates have…
Metallurgical Characterization of Two 11th–12th Century Single-Bow Shears from Sigtuna, Sweden
Shears, being everyday objects, have received significantly less attention by archaeometallurgists than other edged tools or weapons. Yet, shear blades were forged with the same techniques as blades of, e.g. knives and swords. The most common shear type in ancient times was the bow shears, where the bow had to be flexible so it could be repeatedly bent without cracking or breaking. The shear-maker, therefore, faced the challenge of combining hard…
Sexual dimorphism in mastoid process volumes measured from 3D models of dry crania from mediaeval Croatia
3D analysis of skeletal volumes has become an important field in digital anthropology studies. The volume of the mastoid process has been proposed to display significant sexual dimorphism, but it has a complex shape and to date no study has quantified the full mastoid volume for sex estimation purposes. In this study we compared three different ways to isolate the volume of the mastoid process from digital 3D models of dry crania, and then evalua…
Metal residues in 5th c. BCE–13th c. CE Estonian tools for non-ferrous metal casting
Residue analysis, use-wear patterns, and replicative studies indicate that sandstone tools were used as reamers when producing shell fishhooks on San Nicolas Island, California
New applications of 3D modeling in artefact analysis
Residue analysis links sandstone abraders to shell fishhook production on San Nicolas Island, California
Fluted point manufacture in eastern North America
Differences in Paleoindian projectile point morphology have previously been used to define technologies, infer colonization patterns, propose chronological and regional boundaries. In this study, we evaluate the effectiveness of traditional linear measurements and ratios, flake scar angles, and 3D model-based flake contours for the statistical differentiation of projectile point type(s) and reduction technique. Sixty-three fluted bifaces from eas…
Flake scar patterns of Clovis points analyzed with a new digital morphometrics approach
Comparison of coordinate measurement precision of different landmark types on human crania using a 3D laser scanner and a 3D digitiser
A total of 11 340 Cartesian coordinates of 42 homologous landmarks on five excavated human crania were recorded by three observers using a three-dimensional (3D) digitiser and computer models created with a 3D laser scanner. The aim was to compare the errors of the coordinate data of landmarks of different types recorded with these two techniques. The results showed that digitiser-based and 3D model-based coordinate measurements had overall stand…
Metallurgical findings from a Viking Age chieftain’s farm in Iceland
Brief communication
This article identifies and discusses seven new cases of complete maxillary canine‐premolar transposition in ancient populations from the Santa Barbara Channel region of California. A high frequency of this tooth transposition has been previously documented within a single prehistoric cemetery on one of the Channel Islands. A total of 966 crania representing 30 local sites and about 7,000 years of human occupation were examined, revealing an abno…
