    A geoarchaeological reassessment of the co-occurrence of the oldest Acheulean and Oldowan in a fluvial ecotone from lower middle Bed II (1.7ma) at Olduvai Gorge (Tanzania)
    (Quaternary International, 2019) Uribelarrea Del Val, David; Martín Perea, David Manuel; Diez-Martín, Fernando; Baquedano, Enrique; Mabulla, Audax Z.P.; Barba, Rebeca; Gidna, Agnes; Domínguez-Rodrigo, Manuel
    The coexistence of the oldest Acheulean and Oldowan industries means that the appearance of the former cannot be due to an anagenetic development from the latter. At Olduvai Gorge, Tanzania, both industries are found within the same chronostratigraphic unit, the Lower Augitic Sandstone (LAS; 1.7 Ma), at HWK, HWK-E, HWK-EE (Oldowan) and FLK-W and FLK-N (Acheulean). Recently, McHenry and Stanistreet (2018) and Stanistreet et al. (2018) have argued that the Acheulean site of FLK West is actually located within a more recent stratigraphic unit, the Middle Augitic Sandstone (MAS). If so, the Acheulean could potentially have evolved from the Oldowan anagenetically. We test this hypothesis by reviewing the stratigraphy of the LAS from the HWK area to the FLK-W site. Hay's (1976) previous work stresses the continuity of the LAS from HWK-EE to FLK-NN, and stratigraphic and sedimentological evidence indicates that while the MAS has eroded away, the LAS is continuous throughout the study area. According to Hay (1976), Uribelarrea et al. (2017) and this work, the LAS is present at HWK-EE, HWK-E, HWK, HWK-W, FLK-S, FLK-W, FLK-N and FLK-NN. The emergence of the Acheulean at Olduvai Gorge ca. 1.7Ma and its coexistence with the Oldowan thus demonstrates a cladogenetic, rather than an anagenetic, origin for the Acheulean. This has implications for the behavioral and biological interpretations of the origin and co-existence of both types of industries.

    Cut marks and raw material exploitation in the lower pleistocene site of Bell's Korongo (BK, Olduvai Gorge, Tanzania): A geometric morphometric analysis
    (Quaternary International, 2019) Courtenay, Lloyd A.; Yravedra Sainz De Los Terreros, José; Aramendi, Julia; Maté-González, Miguel Ángel; Martín Perea, David Manuel; Uribelarrea Del Val, David; Baquedano, Enrique; González Aguilera, Diego; Domínguez-Rodrigo, Manuel
    The Lower Pleistocene site of Bell's Korongo (BK) in Olduvai Gorge (Tanzania) has been a key site for the study of the origin of human behaviour. The lower archaeological levels of BK are characterized by anthropogenic activity related to the exploitation of megafauna (elephant, hippopotamus, Sivatherium) and smaller game (zebra, wildebeest and antelopes). These remains display a high frequency of cut marks. The exceptional state of preservation of the BK fossil assemblage has allowed a wide range of different analyses that, among other things, detected the use of quartzite in butchering activities through the study of cut marks. Following up previous analyses, this paper presents the study of a series of cut marks from the BK faunal assemblage using a 3D geometric morphometric methodological approach in order to determine the mineralogical properties of the quartzite used at the site. BK cut marks are compared with experimentally produced cut marks using 9 mineralogically different quartzite types from Olduvai Gorge. This comparative analysis provides valuable hints about the exact nature of the raw materials used in butchering activities. The results presented here identify a preferential use of quartzite with a finer granular composition, suggesting that hominin populations were already selecting the best raw materials for their use in specific activities 1.3 Mya.

    Experimental approaches to the development of use-wear traces on volcanic rocks: basalts
    (Archaeological and Anthropological Sciences, 2020) Bello Alonso, Patricia; Rios Garaizar, Joseba; Panera Gallego, Joaquín; Martín Perea, David Manuel; Rubio Jara, Susana; Pérez González, Alfredo José; Rojas Mendoza, Raquel; Domínguez-Rodrigo, Manuel; Baquedano, Enrique; Santonja, Manuel
    In this paper we present the experimental results obtained for the formation of use-wear traces on four types of basalt rocks from the Olduvai Gorge (Tanzania) and one from the Deba River (Spain). The objective of this study is to create a reference collection that will allow the posterior analysis and identification of archeological use-wear traces on lithic industries made on these different types of basalt, such as the Acheulean lithic industry from Thiongo Korongo site (TK) (Olduvai’s Bed II, ca. 1.353 ± 0.035 Ma.). This study includes five types of basalt, under the objective of understanding in more detail the formation of the use-wear traces. Additionally, we include their individual petrographic, chemical, and traceological interpretations, allowing for an assessment of the intrinsic characteristics in relation to the development of use-wear. The final step of this process includes microscopic analysis for the detailed characterization and description of these use-wear traces. The results obtained reveal the internal structure of basalts as a significant conditioning factor in the development of use-wear traces. Despite this, we have been able to establish several criteria that discriminate between actions and different worked materials. These results offer a fundamental experimental basis for the future interpretation of use-wear traces found in archeological basalts.
