    The Dorothy Garrod Site: a new Middle Stone Age locality in Olduvai Gorge, Tanzania
    (Archaeological and Anthropological Sciences, 2022) Maíllo Fernández, José Manuel; Marín, Juan; Martín Perea, David Manuel; Uribelarrea del Val, David; Asiaín Román, Raquel; Solano Megías, Irene; Baquedano, Enrique; Domínguez Rodrigo, Manuel; Gidna, Agness; Medialdea, Alicia; Steven, Hekima Mwamakimbula; Chilonzi, Daniel Haruni; Arteaga, Carlos; Mabulla, Audax
    Olduvai Gorge (Tanzania) is a key site for the study of human evolution as well as the origin of modern humans and the Middle Stone Age (MSA). In this study, we present a new MSA location named Dorothy Garrod Site (DGS), found in the main branch of Olduvai Gorge. The site has only one archaeological level, located stratigraphically in the Upper Ndutu. Although it has not yet been possible to radiometrically date it, it has yielded numerous archaeological remains with a functional association between the faunal remains and the lithic industry. The fauna identified includes Alcelaphini, Hippotragini, and Equidae, some of which present percussion marks and evidence of burning. The lithic industry involved knapping using discoid methods. The retouched blanks are denticulates and retouched flakes with, up to now, a total absence of points. DGS is therefore a new site that will aid our understanding of modern human occupations in northern Tanzania in a period for which there is a dearth of properly contextualised archaeological evidence.

    Victoria Cabrera Site: A Middle Stone Age site at Olduvai Gorge, Tanzania
    (Quaternary International, 2019) Maíllo-Fernández, José-Manuel; Marín, Juan; Solano Megías, Irene; Uribelarrea del Val, David; Martín Perea, David Manuel; Aramendi, Julia; Medialdea, Alicia; Arteaga, Carlos; Pernas Hernandez, Marta; Gidna, Agnes; Neogi, Sayantani; Baudot, Eva; Narváez, Carlos; Mabulla, Audax
    Olduvai Gorge (Tanzania) is a key site for the study and comprehension of human evolution in East Africa. However, the origin of Homo sapiens and the Middle Stone Age have been poorly understood in the Gorge thus far. In this study, we present the dating, taphonomic, technological and typological analyses of the lithic industry and faunal remains excavated at the Victoria Cabrera Site (VCS) during the 2017 fieldwork season. The stratigraphic sequence of the site contains several levels of fluvial origin, some of them with lithic and faunal remains. Most remains (lithics and bones) are affected by rounding processes. Infrared stimulated luminescence (IRSL) dating has provided ages between 90 and 70 ka BP for these layers that can be related to the Marine Isotope Stage 5a. Lithics are scarce and the dominant raw materials are Naibor Soit quarzite and basalt, followed by phonolite, chert and quartz as the most common raw materials. The lithic technology is based on the production of flakes obtained from prepared cores, with the discoid method and, to a lesser extent the Levallois method being the most frequently used. The retouched blanks are described as “substratum” or “domestic” tools (sidescrapers, notches or denticulates). There is just one heavy duty piece and points are absent. The faunal assemblage includes Alcelaphinae, Antilopinae and Equidae. The major parts of the unidentified faunal remains are size 3 ungulates, followed by carcasses of size 2 and size 4 species. We cannot relate lithic and bones because no cut marks or percussion marks have been identified and carnivore action is scarce. In sum, VCS represents the first accurately dated Middle Stone Age site, with lithic and faunal remains in Olduvai Gorge.
