“…This terrace has an estimated age of about 0.85 Ma (Benito-Calvo et al, 2017;Moreno et al, 2012) which is consistent with the proposed dates for the end of TD2 (about 0. 89 Ma; Duval et al, 2022). This stratigraphic section mainly matches with the Railway Trench borehole (BH2 in Bermejo et al, 2020), composed of fine clays and fine sands.…”

“…Therefore, the cementations found in the TD1 and TD2 sequence would indicate vadose conditions (Springer & Kite, 1997a, 1997b. Based on the last dating study of TD1, which inferred an age of about 1.4 Ma for the base of this deposit (Duval et al, 2022), the sedimentation of Gran Dolina cave began shortly after its vadose incision. TD1.2 represents the first registered sedimentation of Gran Dolina cave; it starts with the layer TD1.2.4 composed of laminated silty sand (facies A1) dipping towards the West.…”

“…The assignment of these sediments to autochthonous facies was due to comparison with the clastic sediments of Gran Dolina, defined as allochthonous facies, and because the Sierra de Atapuerca karst was less understood. The use of this terminology has been challenged since a possible fluvial origin for TD1 and TD2 has been previously postulated by different studies based on sedimentology (Campaña, 2018), particle shape analyses (Campaña et al, 2016), and geochronology (Duval et al, 2022;Parés et al, 2018). Although TD1 and TD2 are sterile lithostratigraphic units, their study is necessary to understand the evolution of the karst system, providing key information about the formation and sedimentation processes in the cavities during the persistence of water table conditions related to fluvial phreatic levels.…”

“…The formation of the middle level of the karst, where Gran Dolina cave belongs, was related to the terrace T3 of the Arlanzón River (Benito-Calvo et al, 2017), which was dated by ESR to 1.14 ± 0.13 Ma (Moreno et al, 2012). Recently, TD1 and TD2 have been dated by Electron Spin Resonance (ESR) and single-grain thermally transferred optically stimulated luminescence (SG TT-OSL) methods applied to quartz grains, in combination with magnetostratigraphy, constraining these units to between ~ 1.4 Ma and ~ 0.9 Ma (Duval et al, 2022;Parés et al, 2018). This chronology means that the sedimentary deposit of Gran Dolina cavity started quickly after its formation.…”

Gran Dolina is a cavity infilled by at least 25 m of Pleistocene sediments divided into 12 lithostratigraphic units and 19 sedimentary facies. These sedimentary facies have been divided into allochthonous facies, defined as sediment inputs from the outside, and autochthonous facies, defined as sediments generated within the karst; but this division has been challenged in recent works. In this study, TD1 and TD2 units of Gran Dolina have been detailed studied and the use of autochthonous facies has been assessed. For that purpose, we have studied the stratigraphic excavation profile, combining field observation with laboratory sedimentary analysis (sieving, laser diffraction, and XRD) to characterize the texture and structure of the sediments. Based on these studies, a total of 8 sedimentary facies have been identified. Consequently, TD1 unit has been separated into two sub-units and 13 layers, while the TD2 unit has been divided into three sub-units. The facies associations indicate a succession of phreatic and vadose phases that would define together epiphreatic conditions inside the cave, related to the transition between Arlanzón valley terraces T3 and T4. Interior facies (and entrance facies for allochthonous facies) is proposed to define Gran Dolina's sediments since the facies analyses indicate transport by underground flows.

This paper presents the zooarchaeological, technological, use-wear, and spatial analyses of the earliest sedimentary subunits of TD10 (TD10.3 and TD10.4) of the Gran Dolina site (Sierra de Atapuerca, Burgos, Spain), dated to c. 400 ka. Both units have yielded Acheulean technology, with occupational models characterized by the superimposition of multiple and independent events paired with short, sporadic occupations. Subunits TD10.3 and TD10.4 formed during a period in which the cave was largely reopened after a temporary closure. This period of reopening is evidenced by several blocks that fell from the ceiling and walls. Fifty-seven groups of refits and anthropic conjoins, of which 43 resulted from deliberate hominin activity, confirm the low disturbance of the deposits. Contrary to TD10.4, TD10.3 shows good preservation of faunal remains, although anthropogenic modifications are very scarce. Technologically, both deposits represent well-developed Acheulean assemblages, with high proportions of large-shaped tools and percussive material, which place this area among those that have yielded the most evidence of this type among all the excavated Atapuerca sites. The question of why these subunits contain so many hammerstones, manuports, and large tools associated with faunal remains that have been so scarcely modified is discussed based on data from spatial, technical, and use-wear analyses, which have identified butchery activities, and for the first time in the Pleistocene Atapuerca record, borer elements and possible thrusting stone spear tips. Furthermore, the occupational and technological characteristics of these subunits were compared with other western European archaeological sites, including the nearby site of Galería, with which a broad correlation can be made.
