Arqueología tridimensional. Las técnicas 3D aplicadas al registro paleolítico// Tridimensional Archaeology. 3D techniques applied to the paleolithic record.

3D techniques are nowadays widely used in a variety of heritage studies. The so-called “virtual archaeology” constitutes a good example of the growing strength accomplished by these techniques. Paleolithic studies have incorporated an increasing number of 3D routines in fieldwork,lithic, fossil bone and rock art studies, in order to enhance their analytical and interpretative tools. In this paper we present an updated review of the current uses and future possibilities of 3D techniques applied to Archaeology, particularly focusing on the Paleolithic record. In order to show the way in which the array of 3D techniques can be applied in Lower Palaeolithic contexts, two case studies are presented here. Through the digitalization of Acheulean lithic artefacts, the first example shows to what extent both formal representation and technological interpretation can benefit from 3D representation. Secondly, by comparing more traditional drawing procedures andphotogrammetry we aim to stress how the later constitutes a much more efficient tool for data recovery and management in on-site archaeological fieldwork. In sum, this paper underlines how a wide range of archaeological procedures and studies can benefit from 3D technologies
