Archaeological indicators of cognitively modern behaviour become increasingly prevalent during the African Middle Stone Age (MSA). Although the exploitation of ochre is viewed as a key feature of the emergence of modern human behaviour, the uses to which ochre and ochre-based mixtures were put remain ambiguous. Here we present the results of an exp...

The islands of Guadeloupe deliver some caves and rock shelters occupied in precolumbian times, including rare engraved caves whose age of occupation remains unclear and some burial caves used in the Late Ceramic Age. Question arises whether the absence of engravings in these latter sites reflects an archaeological reality or, in contrast, is linked...

Detailed stratigraphic analysis and numerical dating (OSL, IRSL, ESR, 14C) of Pleistocene coversands in southwest France enable the construction of a renewed chronostratigraphic framework for sand depo-sition. The chronological data obtained from sandsheet units testify to the development of transgressive dunefields since at least the Middle Pleist...
Article
The production of purposely made painted or engraved designs on cave walls—a means of recording and transmitting symbolic codes in a durable manner—is recognized as a major cognitive step in human evolution. Considered exclusive to modern humans, this behavior has been used to argue in favor of significant cognitive differences between our direct a...

Fully shaped, morphologically standardized bone tools are generally considered reliable indicators of the emergence of modern behavior. We report the discovery of 23 double-beveled bone tools from ~ 80,000-60,000-year-old archaeological layers at Sibudu Cave in KwaZulu-Natal, South Africa. We analyzed the texture of use-wear on the archaeological b...

Upper Paleolithic sites in southwestern France attributed to the Upper Gravettian and the Solutrean yielded sub spherical gravels with a highly shiny appearance that have intrigued researchers since the 1930s. In this work, we analyze specimens from five sites, including the recently excavated Solutrean site of Landry, to establish whether their pr...

Personal ornaments are a very specific kind of material production in human societies and are particularly valuable artifacts for the archaeologist seeking to understand past societies. In the Caribbean, Early Ceramic Age sites have yielded a highly diverse production both in terms of raw materials and typology. In recent years they have been the s...

Very diverse lapidary artwork, both in style and raw materials, is one of the recognized specialty of Amerindian crafting during the Saladoid period in the Antilles area, and is supposed to be less numerous and diverse in the following periods. These gemstones are very often referred to as exotic since they are not coming from the island where they...

Lapidary craftsmanship was an important part of the material culture of Amerindians in the Antilles during the Early Ceramic period (400 BCE to 400 CE). Exhaustive analysis of archaeological beads and pendants from the French islands of the Lesser Antilles has revealed a green lapidary material used for the production of nine artifacts from five ar...

The origin and development of osseous technology remains poorly documented to this day. From the first evidence of utilized bone fragments in East and South Africa, some ~2Myr ago, until the appearance of formal bone tools ~90 ka in Africa, and ~45 ka in the rest of the Old World, the archaeological record provides a limited number of specimens sca...

The origin and development of osseous technology remains a central focus to palaeoanthropological studies. Recognizing expedient bone tools, however, is not easy as many taphonomic processes converge to produce confounding modifications on faunal remains. Understanding what was their function is even more difficult owing to the limited number of st...

The origin and evolution of hominin mortuary practices are topics of intense interest and debate1–3. Human burials dated to the Middle Stone Age (MSA) are exceedingly rare in Africa and unknown in East Africa1–6. Here we describe the partial skeleton of a roughly 2.5- to 3.0-year-old child dating to 78.3 ± 4.1 thousand years ago, which was recovere...

Carving a figurine requires the ability to mentally visualize a volume in matter and create symmetries in a three-dimensional space. During the Paleolithic, such objects were likely made to be transported, curated, manipulated, and hung on clothing. Thus far, no instances of three-dimensional portable art were documented in East Asia before the Neo...

We used classical field and laboratory methods. Names of formations and the definition of units follow international stratigraphic rules (Salvador, 1994). The description of sedimentary units, when possible, uses Miall's terminology for architecture and facies (1978, 1992, 2006), keeping in mind that the scale of the outcrops considerably limits in...
