“…Pante et al 2017), although the technique still needs developing properly before being useful for interpreting bone surface modifications of fossils. As Pante et al (2017) acknowledge 'the measurements recorded by the three analysts were not identical' because 'differences in the position and orientation of the mark relative to the optical pen resulted in small variations in the data captured'. Even if it is assumed that these derived mark sections are as close to the real mark sections as confocal microscopy can get, the resulting sections obtained are highly dependent on the protocol used for scanning each mark.…”

Dom ınguez-Rodrigo, M. 2017 (October): A new approach to raw material use in the exploitation of animal carcasses at BK (Upper Bed II, Olduvai Gorge, Tanzania): a micro-photogrammetric and geometric morphometric analysis of fossil cut marks.The use of innovative techniques such as micro-photogrammetry and geometric morphometrics may have a major impact on the differentiation of cut marks made with different raw materials and, thus, link butchering processes with stone tool reduction sequences. This work focuses on a sample of cut-marked bones from the Bell's Korongo (BK) site (Upper Bed II, Olduvai Gorge, Tanzania), which is an emblematic early Pleistocene site where a large faunal assemblage, including a diverse megafauna, occurs in association with quartzite and basalt industries. We present a detailed study of a sample of 58 cut marks identified on a set of recently excavated BK fossils, using a micro-photogrammetric and geometric morphometric approach, with the aim of identifying the raw materials used in the butchery of carcasses. In order to carry out this study, we previously carried out an experimental analysis to characterize cut marks and their morphology according to the types of raw material found at BK, namely quartzite and basalt. The results from the experimental study show that there is a good fit between raw material type and cut mark morphology, enabling us to confidently apply this method to the analysis of the cut marks of the BK fossil assemblage. The present study shows that most of the BK cut marks were created by the use of quartzite tools. The efficiency of this type of raw material is emphasized, which explains its curation over the landscape by hominins. Jos e Yravedra

“…Although Pante et al . () qualified the M‐PG method as more inaccurate and prone to error, this prejudiced statement was not supported by any data. Here we show that M‐PG meets the standards of more costly and technologically more sophisticated techniques, such as the use of LSCM, and M‐PG may even exceed the quality of the results obtained via 3D DM.…”

In the last few years, the study of cut marks on bone surfaces has become fundamental for the interpretation of prehistoric butchery practices. Due to the difficulties in the correct identification of cut marks, many criteria for their description and classification have been suggested. Different techniques, such as three-dimensional digital microscope (3D DM), laser scanning confocal microscopy (LSCM) and micro-photogrammetry (M-PG) have been recently applied to the study of cut marks. Although the 3D DM and LSCM microscopic techniques are the most commonly used for the 3D identification of cut marks, M-PG has also proved to be very efficient and a low-cost method. M-PG is a noninvasive technique that allows the study of the cortical surface without any previous preparation of the samples, and that generates high-resolution models. Despite the current application of microscopic and micro-photogrammetric techniques to taphonomy, their reliability has never been tested. In this paper, we compare 3D DM, LSCM and M-PG in order to assess their resolution and results. In this study, we analyse 26 experimental cut marks generated with a metal knife. The quantitative and qualitative information registered is analysed by means of standard multivariate statistics and geometric morphometrics to assess the similarities and differences obtained with the different methodologies.

Questions about the timing, frequency, resource yield, and behavioral and biological implications of large animal carcass acquisition by early hominins have been a part of the “hunting‐scavenging debate” for decades. This article presents a brief outline of this debate, reviews the zooarchaeological and modern ecological evidence for a possible scavenging niche among the earliest animal tissue‐consuming hominins (pre‐2.0 Ma), revisits some of the questions that this debate has generated, and outlines some ways to explore answers to those questions with evidence from the archaeological record.
