“…Other drawbacks in applying these results to the archaeological record include the feasibility of scanning and land-marking large archaeological collections at this point in time. However, the efficiency of scanning technologies and the availability of digital methodologies for landmarking stone artefacts have both increased at an exponential rate within just the last 5 to 6 years (Bretzke and Conard 2012;Grosman 2016;Morales et al 2015). Applying these newly available digital tools to wider ranges of experimental as well as archaeological flake collections and in pursuit of tackling more complex questions about the technological behaviour of past hominins comprise exciting new avenues of this research.…”

“…For instance, using a digital imaging technique to capture platform area, Braun et al (2008) demonstrated that these digital measures have the potential to explain much more flake size variation than calliper-based measurements. This improvement in explanatory strength may be partly attributed to a lower measurement error associated with these approaches (Braun et al 2008;Morales et al 2015;Muller and Clarkson 2014). However, this improvement may also be associated with the ability of digital methods to more holistically capture aspects of platform variability which are important for explaining flake variation, but which are difficult to capture with standard linear measurements.…”

The archaeological record represents a window onto the complex relationship between stone artefact variance and hominin behaviour. Differences in the shapes and sizes of stone flakes-the most abundant remains of past behaviours for much of human evolutionary history-may be underpinned by variation in a range of different environmental and behavioural factors. Controlled flake production experiments have drawn inferences between flake platform preparation behaviours, which have thus far been approximated by linear measurements, and different aspects of overall stone flake variability (Dibble and Rezek J Archaeol Sci 36:1945-1954 Lin et al. Am Antiq 724-745, 2013; Magnani et al. J Archaeol Sci 46:37-49, 2014; Rezek et al. J Archaeol Sci 38:1346-1359, 2011. However, when the results are applied to archaeological assemblages, there remains a substantial amount of unexplained variability. It is unclear whether this disparity between explanatory models and archaeological data is a result of measurement error on certain key variables, whether traditional analyses are somehow a general limiting factor, or whether there are additional flake shape and size drivers that remain unaccounted for. To try and circumvent these issues, here, we describe a shape analysis approach to assessing stone flake variability including a newly developed three-dimensional geometric morphometric method ('3DGM'). We use 3DGM to demonstrate that a relationship between platform and flake body governs flake shape and size variability. Contingently, we show that by using this 3DGM approach, we can use flake platform attributes to both (1) make fairly accurate stone flake size predictions and (2) make relatively detailed predictions of stone flake shape. Whether conscious or instinctive, an understanding of this geometric relationship would have been critical to past knappers effectively controlling the production of desired stone flakes. However, despite being able to holistically and accurately incorporate three-dimensional flake variance into our analyses, the behavioural drivers of this variance remain elusive.

“…methods for estimating the amount or effects of mass removed from a flake or tool by retouch or resharpening-has received extensive coverage in the literature (Andrefsky 2006;Bradbury, Carr, and Randall Cooper 2009;Braun et al 2010;Clarkson 2002;Davis and Shea 1998;Eren et al 2005; Eren and Prendergast 2008; Eren and Sampson 2009;Hiscock and Clarkson 2005;Horowitz and McCall 2013;Patten 2005;Shott et al 2000Shott et al , 2007Marwick 2008;Morales, Lorenzo, and Vergès 2015;Wilson and Andrefsky 2008), but with some exceptions, it has not been intensive. Rather, researchers have focused on using an experiment for the purpose of proposing new or newly revamped methods rather than for thoroughly vetting methods and validating that they actually work for their asserted purpose (Shott et al 2007:205-206).…”

“…Por un lado permiten la documentación completa y la integración del material arqueológico, como en el caso del escaneo de niveles arqueológicos y los artefactos asociados a ellos que se llevó a cabo en diversos yacimientos del Paleolítico Medio en Francia (McPherron et al, 2009) o en proyectos que utilizan las tecnologías digitales para obtener documentación más detallada (Doneus et al, 2003;Martínez Lerones et al, 2009;Mostaza et al, 2010). También resultan muy útiles a la hora de realizar la sistematización de los análisis métricos e incluso minimizar los errores de medición (Morales et al, 2013;Grosman et al, 2008). Por otro lado, los modelos digitales son ampliamente utilizados en reconstrucciones y musealizaciones virtuales (Böhler et al, 2008), ligados al desarrollo de la realidad virtual (VR) y que permite la interactuación entre el público, los materiales arqueológicos y el escenario contextual (Barceló et al 2000;Lepouras & Vassilakis, 2005;Bruno et al, 2010).…”

Resumen:Partiendo de la premisa de dinamizar ciertos recursos existentes en el Departamento de Prehistoria y Arqueología (la colección de réplicas osteológicas -crá-neos -y un escáner 3D de superficie) nos propusimos como objetivo componer una colección virtual de referencia de materiales osteológicos accesible, comprensible y funcional, para enriquecer la formación teórico-práctica del alumnado, y contribuir a la mejora de la enseñanza de la evolución humana en los diferentes grados y posgrados de la Universidad de Granada, pero también válido para la investigación Para ello, se procedió a digitalizar, con un escáner 3D de luz estructurada Artec2000, 25 réplicas de cráneos de individuos significativos para el estudio de la evolución humana y pertenecientes a los principales taxones extintos (australopitecinos -en sentido amplio-y Homo). Además, se realizaron fichas de cada uno de ellos con información relativa a su descubrimiento y adscripción, así como de algunas de las principales variables métricas craneales (volumen endocraneal, tres del neurocráneo y otras del tres viscerocráneo) que se hallaban dispersas en la literatura científica. Dicha información junto con las reproducciones digitales configuran una base de datos alojada en una página web "la craneoteca del Dpto. de Prehistoria y Arqueología de la UGR", de libre acceso desde cualquier computadora con Internet (www.prehistoriayarqueología.es/craneoteca). Palabras clave:Cráneos, docencia, escáner 3D, evolución humana, nuevas tecnologías. Abstract:Based on the premise of boosting certain resources of the Department of Prehistory and Archaeology (the collection of osteological replicas -skulls -regarding Human Evolution and the 3D scan) we focused our aim in creating a virtual reference collection of the osteological material in an accessible, comprehensible, functional way, in order to improve the theoretical-practical training of students and therefore contribute to enrich teaching of Human Evolution in the different graduate and postgraduate studies at the University of Granada, but also suitable for Research.
