The Rules are the Rules. Consistency of Drivers of Flake Size and Shape in Mechanical Flaking Experiments
Lithic flakes are central to Paleolithic assemblages, and their variability provides key insights into stone-tool technology, decision making, and hominin motor control. Mechanical flaking experiments isolate the main drivers of flake size and shape, but most have used glass plates or cuboid cores with Levallois-like surfaces. These standardized forms have clarified relationships among flake mass, platform depth, angle of blow, exterior platform …
Microscope agnosticism and the characterization of sedimentary abrasion of flint stone tools
Different microscopes might capture the same surface on different manners. • This can affect the quantitative features extracted from the images. • These problems are addressed when characterizing flint sedimentary abrasion. • Images and data from two microscopes are compared. • Despite differences in images, sedimentary abrasion is well characterized. The surface of lithic stone tools from Paleolithic archaeological sites can undergo a range of …
The Contribution of 2D and 3D Geometric Morphometrics to Lithic Taxonomies
Paleolithic lithic assemblages are usually dominated by flakes and display a high degree of morphological variability. When analyzing Paleolithic lithic assemblages, it is common to classify flakes into categories based on their morphological and technological features, which are linked to the position of the flake in the reduction sequence and how removals are organized in a given production method. For the analysis of Middle Paleolithic lithic …
The quantification of surface abrasion on flint stone tools
Lithic artifacts are some of the most common and numerous remains recovered from paleolithic archaeological sites. However, these materials can undergo multiple post‐depositional alterations after their introduction into the archaeological record. Due to the high quantity of lithic remains recovered, a quick, flexible, and effective method for identifying degrees of alteration on the surface of lithic implements is highly desirable. The present s…
What lies in between
Lithic artefacts are usually associated with the different knapping methods used in their production. Flakes exhibit metric and technological features representative of the flaking method used to detach them. However, lithic production is a dynamic process in which discrete methods can be blurred, and in which features can vary throughout the process. An intermediate knapping method between the discoid and Levallois is commonly referred to under …
Multiple approaches to predicting flake mass
Predicting original flake mass is a major goal of lithic analysis. Predicting original flake mass allows for researchers to make estimations of remaining mass, lost mass, and other features. All these measures relate to the organization of lithic technology by past societies. The present work tests three different models to predict log of flake mass: multiple linear regression, random forest regression, and artificial neural networks (ANN). Estim…
Combining quantitative approaches to differentiate between backed products from discoidal and Levallois reduction sequences
Backed flakes (core edge flakes and pseudo-Levallois points) represent special products of Middle Paleolithic centripetal flaking strategies. Their peculiarities are due to their roles as both a technological objective and in the management of core convexities to retain its geometric properties during reduction. In Middle Paleolithic contexts, these backed implements are commonly produced during Levallois and discoidal reduction sequences. Backed…
Predicting Flake Mass
Estimating flake mass based on remaining attributes bears an important relationship for the interpretation of lithic assemblages. Previous works have pointed out the relationship between flake attributes and prediction of flake mass. This study builds on previous works by using data from an experimental collection of flakes. Estimated mass was arrived at by generating a multiple linear regression model that combines several predictive variables. …
Exploring volume lost in retouched artifacts using height of retouch and length of retouched edge
An Experimental Approach to Degrees of Rounding Among Lithic Artifacts
Quantitative and qualitative analysis for the study of Middle Paleolithic retouched artifacts
Experimental study on flint hammerstone use in Discoid-Levallois technologies
The basins of the Manzanares and Jarama rivers have been connected to human activity since the early Palaeolithic. At the boundary between these rivers the abundance of flint has given place to exploitation and mining activities even in historical times. In recent years, projects related to urban expansion in the southeast of Madrid have brought to light various Palaeolithic deposits associated with workshops and tool production. These sites do n…
Preliminary experimental insights into differential heat impact among lithic artifacts
The presence of thermally altered and broken flint artifacts is common at archaeological sites. Most studies focus their attention on the effects of heat treatment on flint to improve knapping qualities, disregarding the effects of fire over flint under uncontrolled conditions. This paper aims to show how under uncontrolled heating processes flint artifacts develop different heat alterations (such as levels of breakage, presence of scales, etc.) …
