Homo sapiens was present in northern Asia by around 40,000 years ago, having replaced archaic populations across Eurasia after episodes of earlier population expansions and interbreeding1,2,3,4. Cultural adaptations of the last Neanderthals, the Denisovans and the incoming populations of H. sapiens into Asia remain unknown1,5,6,7. Here we describe Xiamabei, a well-preserved, approximately 40,000-year-old archaeological site in northern China, which includes the earliest known ochre-processing feature in east Asia, a distinctive miniaturized lithic assemblage with bladelet-like tools bearing traces of hafting, and a bone tool. The cultural assembly of traits at Xiamabei is unique for Eastern Asia and does not correspond with those found at other archaeological site assemblages inhabited by archaic populations or those generally associated with the expansion of H. sapiens, such as the Initial Upper Palaeolithic8,9,10. The record of northern Asia supports a process of technological innovations and cultural diversification emerging in a period of hominin hybridization and admixture2,3,6,11.

Extended data figures and tables
a, Periosteal view of the shaft fragment. b, Close-up view of the distal area showing microflake scars, smoothing and striations. c, Scraping regularizing the edge close to the opposite end. The object is an elongated fragment of a long bone from a medium-sized mammal. The bone is in an excellent state of preservation, apart from a large notch and post-depositional chipping located on both sides and rare flaking of the periosteal surface, at places removing primary bone lamellae. The edge of the rounded end displays micro flake scars strongly worn by usewear. The adjacent surface is covered with groups of microscopic striations subparallel or oblique to the main axis of the object that fade in frequency away from the edge. The left edge of the opposite end, which is pointed in shape, has been regularized by scraping with a lithic tool so as to make the edges of the bone less sharp. The adjacent periosteal surface also bears longitudinal striations, due to scraping, as well as groups of short striations perpendicular to the major axis of the object. The marks present on the rounded end are consistent with the object being used as a scraper on a soft material, strewn with abrasive particles. The modifications on the opposite end were intended to facilitate hafting of the object or its gripping during work.
a, Ochre piece OP1, numbers indicate the analyzed areas (zone 1: grey polished area; zone 2: purple granular area; zone 3: coarse-grained area; zone 4: blistered area). b, drawing of ochre piece OP1, grey areas represent flake scars. c–f, SEM images of ochre piece OP1 (zones 1 to 4 respectively): grey polished area (c); purple granular area (d); coarse-grained area (e); blistered area (f). g, µ-Raman spectra obtained from the analysis of zone 1 (grey polished area, spectrum 1) and zone 3 (coarse-grained area, spectrum 2) showing the presence of hematite (H) and quartz (Q). The hematite reference spectrum is indicated in red: RRUFF ID R11001398. OP1 (28 x 20 mm in size; 12,4 g in mass) is a fragment of a larger nodule showing a portion of the original curved outer surface and several flake scars. The outer surface features a cracked and pitted texture alternating compact (grey polished area, zone 1 in a) and granular zones (purple granular and coarse-grained areas, zones 2 and 3 respectively in a). The flake scars feature a homogeneously blistered structure partially hidden on one surface by a yellow and on another by a dark red coating (blistered area, zone 4 in a). The blisters are smoother on some surfaces. Differential alteration indicates different episodes of fragmentation, probably due to knapping.
a, Ochre piece OP2, number indicates the area analyzed using SEM-EDS. b, c, SEM images of ochre piece OP2. d, µ-Raman spectrum obtained from the analysis of OP2 showing the presence of hematite (H), quartz (Q), and an undetermined manganese oxide (Und). The hematite reference spectrum is indicated in red: RRUFF ID R11001398. OP2 (11 x 8 mm in size; 0.6 g in mass) preserves at its base (at the bottom) a dark brown flat area representing the outer surface of an originally larger ochre lump of which OP2 is a small fragment. OP2 likely results from pounding that larger piece. More heterogeneous and porous than OP1, it bears no other evidence of deliberate modification.
a, Views of the QC with indication of the area enlarged in b. b, Flat pitted area of the QC. c, Views of the LS with indication of the area enlarged in (d) and the area on which fragment OMF was retrieved (1). d, Smoothed area with diffused ochre stain. e, Residue OMF with indication of the area analysed using SEM-EDS (1). f, g, SEM images of sample OMF. h, µ-Raman spectrum obtained from sample OMF showing the presence of hematite (H) and an undetermined manganese oxide (Und). The hematite reference spectrum is indicated in red: RRUFF ID R11001398. The quartzite cobble (10 x 9 cm in size) bears pits consistent with grinding and pounding actions on a flat facet (a, b) and on a protuberant zone of the edge. No ochre residues were identified on the surface of the cobble, or on the sediment covering the piece before cleaning. The limestone slab (24 x 16 cm in size) bears smoothed areas on one flat face and one edge as well as a diffuse red stain on the latter (c, d). Sample OMF (e–g) was identified on the edge of the limestone slab that features a red stain (c, zone 1). However, since the smoothed surfaces of the artefact were found in direct contact with the red stain on the sediment (Fig. 3b), it is not clear whether the red residues come from the stained sediment or whether they result from a processing of ochre directly on the surface of the tool.
a, squares indicate areas presented in c–g with same letters. b, grey areas represent surfaces that bear striations produced by grinding. Arrows indicate the direction of the grinding motions. c–e, g, striations observed on OP1. f, 3D reconstruction of an area showing striations. The outer surface of the nodule bears five adjacent areas, each covered by parallel striations produced by abrading the nodule on a grindstone with a to-and-from motion (a, b). OP1 contains inclusions of almost pure iron in a more granular matrix. Abrasion has differentially smoothed areas of different hardness with the harder remaining more prominent. The orientation of the striations slightly differs on each facet indicating changes in the direction of the movement and possibly different sessions of use. The latter hypothesis is supported by substantial differences in the size of the striations between modified areas suggesting abrasion on grindstones of different granulometry (c–g).
Samples X1 and X2 come from the red stained area on which the ochre fragments OP1 and OP2, stone slab LS and quartzite cobble QC were found; and samples X3 and X6 were retrieved Layer 6 but at about 2 m far from the stained area (Supplementary Fig. G1). a, XRD spectra clearly showing that hematite is abundant in samples X1 and X2, and that it is not detected in samples X3 and X6. b, Raman spectra. Data of the reference hematite (CIT-2058) with RRUFF ID X050102 come from the RRUFF Project website (https://rruff.info/hematite/display=default/X050102), see also Anthony et al.61. c, High-temperature magnetic susceptibility measurements. Blue arrows represent the feature of partially-oxidized magnetite; and red arrows, of hematite. d, Magnetic component analysis of coercivity distributions calculated with the IRM-CLG program66. Green, purple, blue and red lines indicate the low-coercivity component (IRML), middle-coercivity component (IRMM), high-coercivity component (IRMH), and the sum of these components (sum), respectively. B1/2 is the field at which half of the saturation IRM (SIRM) is reached; and the dispersion parameter (DP) represents one standard deviation99. BL1/2, BM1/2 and BH1/2 represent B1/2 of the low-, middle- and high-coercivity component, respectively. DPL, DPM and DPH represent DP of the low-, middle- and high-coercivity component, respectively. The high-coercivity component (IRMH) with median acquisition field (BH1/2) of up to 575 mT is interpreted as single domain (SD) hematite, because the SD threshold grain size of hematite is considerably larger than 15 μm, and even up to 100 μm68. This kind of hematite grains with high coercivities up to several hundreds of mT is usually of detrital origin70,100. e, Fe element distribution via Micro-XRF imaging. The yellow arrows point to large (up to 150–200 μm) Fe-rich agglomerates, which probably contain a high proportion of hematite, whose presence is detected by XRD analyses (a), Raman spectroscopy (b) and mineral magnetic measurements (c, d).

a, distribution of MIS 3 sites in northern China (see Supplementary Table A1 for site names. The source of the map https://resources.arcgis.com/). b, field view of Xiamabei. c, view of the excavated section. d, archaeological site distributions. Key features include a red stained patch with artefacts and a hearth and surrounding ashy area. Sediment samples for composition analysis within the excavation area are shown. Notable is the distribution of lithic artefacts and fauna, including the location of a bone tool. Stone tools submmited to use-wear analysis provide evidence for the following activities: hafting to handles; processing of vegetal material; involvement in butchery activities and hide working; perforation of hard material; use as wedges.
