- Mapping the stone age of MozambiquePublication . Gonçalves, Célia; Raja, Mussa; Madime, Omar; Cascalheira, João; Haws, Jonathan; Matos, Daniela; Bicho, Nuno Gonçalo Viana Pereira FerreiraUnder the auspices of the Portuguese colonial government, Lereno Barradas and Santos Junior (coordinator of the Anthropological Mission of Mozambique) carried out several archaeological field surveys from 1936 to 1956 that resulted in a data set that includes a total of close to 90 sites, mostly attributed to the Stone Age. This early research added to the previous work of Van Riet Lowe in the Limpopo Valley of southern Mozambique. With the new millennium, Mozambique has emerged as a crucial geographic area in which to understand the various hypotheses about recent human evolution. Specifically, its coastal location between southern and eastern Africa is ideal for testing ideas about the link between early coastal adaptations and the appearance of anatomically modern humans (AMH). Except for the recent work by Mercader's team in northern Mozambique, the number of researchers and projects on this topic in Mozambique is still limited because of the general predominance of interest in later periods among archaeologists working in the country, mainly due to their focus on issues related to precolonial heritage and national identity. Based on the early maps from Santos Junior and more recent data acquired through various projects, we present a series of maps for the Stone Age prehistory of Mozambique. The maps are also based on a critical evaluation of the sites and a review of some of the materials that are presently curated at the Instituto de Investigacao Cientifica e Tropical (IICT) in Lisbon, Portugal, as well as the materials stored at the Department of Archaeology of Universidade Eduardo Mondlane, Maputo. The sites are also presented in an online database with the information on all sites used in this study. This database is open to all and will be updated continuously. A preliminary interpretation of the regional distribution of the sites is also attempted, linking aspects that include region, topography and altitude, geomorphology, and cultural phase. These results will be the first step for research and knowledge in Mozambique on Stone Age prehistory and the emergence and settlement pattern of AMH.
- Territory and abiotic resources between 33 and 15.6 ka at Vale Boi (SW Portugal)Publication . Pereira, Telmo; Bicho, Nuno Gonçalo Viana Pereira Ferreira; Cascalheira, João; Infantini, Leandro; Marreiros, Joao; Paixão, Eduardo; Terradas, XavierThe environmental shifts during the Late Pleistocene had major influences in the landscape and, consequently, in the available resources. This had direct impact on human behavior and ecology, requiring people to constantly adjust to new economical conditions. In coastal areas, the retreat of the shoreline during the colder phases might have made available presently underwater raw material sources in the form of outcrops and gravels, eventually making it easier to gather lithic raw materials.In this paper, we present our preliminary results on the diachronic variability of raw materials in Vale Boi. Vale Boi is a coastal site, located 2.5 km from the present coastline, in the margins of a freshwater stream. The site has three different loci, all rich in lithics, fauna (including marine), bone tools, adornments, charcoal, and ochre, and evidence of continuous human occupation from c. 33 to 15.6 ka cal BP. This chronostratigraphic record makes it a perfect study case for the understanding of coastal populations' behavior and economy throughout the Upper Paleolithic.Our objective is to infer the territory of resources exploitation, landscape, and economic patterns. Raw material sources are usually fixed points on the landscape (in contrast to other resources such as fauna and flora) and, therefore, are one of the best ways of understanding how people moved in the landscape and, consequently, to infer past human behavior. We used a macroscopic approach in both the archaeological and the geological record in order to correlate sources and artifacts. Despite the absence of detailed quantitative data on each chert type, our results show that the hunteregatherers who occupied Vale Boi during the Upper Paleolithic not only used several raw materials but also a variety of sources of the same raw material. This happened both diachronically and synchronically, suggesting that not only the complete sequence as well as each archaeological layer seem to have had a considerable economic complexity with the use of adjacent and distal sources. With this paper, we aim to present updated information on the variability of raw materials at Vale Boi, including the chert assemblages, along with new chert sources in order to establish a basis for a future detailed study on the raw material sourcing at the site.

- Rapid climatic events and long term cultural change: the case of the Portuguese Upper PaleolithicPublication . Bicho, Nuno Gonçalo Viana Pereira Ferreira; Cascalheira, João; Marreiros, Joao; Pereira, TelmoIn Western Europe, the Upper Paleolithic is marked by clear regional and diachronic technological differences. Some of these are most likely related with human adaptations to the Late Pleistocene environmental shifts. In this paper we focus on the rapid climatic change events and their influence on the Iberian regional ecology and vegetation cover. Based on those changes and their impact on the main Upper Paleolithic cultural phases in central and southern Portugal, we propose an explanatory model, to be tested in the future, where rapid climatic events, such as the D-O and Heinrich Events, have direct impact on the ecology and vegetation cover and this, in turn, cause changes in human adaptations in terms of mobility, settlement patterns, land use and technology.

- The early Aurignacian dispersal of modern humans into westernmost EurasiaPublication . Haws, Jonathan; Benedetti, Lucilla; Talamo, Sahra; Bicho, Nuno Gonçalo Viana Pereira Ferreira; Cascalheira, João; Ellis, M. Grace; Carvalho, Milena M.; Friedl, Lukas; Pereira, Telmo; Zinsious, Brandon K.Documenting the first appearance of modern humans in a given region is key to understanding the dispersal process and the replacement or assimilation of indigenous human populations such as the Neanderthals. The Iberian Peninsula was the last refuge of Neanderthal populations as modern humans advanced across Eurasia. Here we present evidence of an early Aurignacian occupation at Lapa do Picareiro in central Portugal. Diagnostic artifacts were found in a sealed stratigraphic layer dated 41.1 to 38.1 ka cal BP, documenting a modern human presence on the western margin of Iberia ∼5,000 years earlier than previously known. The data indicate a rapid modern human dispersal across southern Europe, reaching the westernmost edge where Neanderthals were thought to persist. The results support the notion of a mosaic process of modern human dispersal and replacement of indigenous Neanderthal populations.
- Early upper paleolithic colonization across Europe: Time and mode of the gravettian diffusionPublication . Bicho, Nuno Gonçalo Viana Pereira Ferreira; Cascalheira, João; Gonçalves, CéliaThis study presents new models on the origin, speed and mode of the wave-of-advance leading to the definitive occupation of Europe's outskirts by Anatomically Modern Humans, during the Gravettian, between c. 37 and 30 ka ago. These models provide the estimation for possible demic dispersal routes for AMH at a stable spread rate of c. 0.7 km/year, with the likely origin in Central Europe at the site of Geissenklosterle in Germany and reaching all areas of the European landscape. The results imply that: 1. The arrival of the Gravettian populations into the far eastern European plains and to southern Iberia found regions with very low human occupation or even devoid of hominins; 2. Human demography was likely lower than previous estimates for the Upper Paleolithic; 3. The likely early AMH paths across Europe followed the European central plains and the Mediterranean coast to reach to the ends of the Italian and Iberian peninsulas.
- Middle and late stone age of the Niassa region, Northern Mozambique. Preliminary resultsPublication . Bicho, Nuno Gonçalo Viana Pereira Ferreira; Haws, Jonathan; Raja, Mussa; Madime, Omar; Gonçalves, Célia; Cascalheira, João; Benedetti, Michael M.; Pereira, Telmo; Aldeias, VeraLocated between modern-day South Africa and Tanzania, both of which have well-known and extensive Stone Age records, Mozambique's Stone Age sequence remains largely unknown in the broader context of African Pleistocene prehistory. Such lack of data occurs despite the key geographical location of the country, in southern Africa at the southeastern tip of the Great Rift Valley. As such, Mozambique is an area of interest to evaluate the origins and dispersion of Homo sapiens within Africa, particularly in relation to Middle Stone Age contexts and associated early modern human ecology and cognition.This paper focuses on preliminary survey results from the Niassa District, near Lake Niassa (also known as Lake Malawi) in northern Mozambique. The results include the discovery and location of more than 80 new surface lithic concentration localities, as well as data from two new sites, the open air surface site of Ncuala and the rock shelter of Chicaza. For Chicaza we provide a series of new radiocarbon dates for the Iron Age and Late Stone Age occupations based on preliminary testing carried out at the site. (C) 2015 Elsevier Ltd and INQUA.

- Portable art and personal ornaments from Txina-Txina: a new later stone age site in the Limpopo River Valley, southern MozambiquePublication . Bicho, Nuno Gonçalo Viana Pereira Ferreira; Cascalheira, João; André, Lino; Haws, Jonathan; Gomes, Ana; Gonçalves, Célia; Raja, Mussa; Benedetti, Michael M.This paper reports on preliminary fieldwork at the Later Stone Age site of Txina-Txina in Mozambique. Excavation yielded a long stratigraphic sequence, a large lithic assemblage, a unique decorated gastropod shell fragment and two ostrich eggshell beadsthe first of their type recovered from a Stone Age context in Mozambique.
- On the chronological structure of the solutrean in Southern IberiaPublication . Cascalheira, João; Bicho, Nuno Gonçalo Viana Pereira FerreiraThe Solutrean techno-complex has gained particular significance over time for representing a clear demographic and techno-typological deviation from the developments occurred during the course of the Upper Paleolithic in Western Europe. Some of Solutrean's most relevant features are the diversity and techno-typological characteristics of the lithic armatures. These have been recurrently used as pivotal elements in numerous Solutrean-related debates, including the chronological organization of the techno-complex across Iberia and Southwestern France. In Southern Iberia, patterns of presence and/or absence of specific point types in stratified sequences tend to validate the classical ordering of the techno-complex into Lower, Middle and Upper phases, although some evidence, namely radiocarbon determinations, have not always been corroborative. Here we present the first comprehensive analysis of the currently available radiocarbon data for the Solutrean in Southern Iberia. We use a Bayesian statistical approach from 13 stratified sequences to compare the duration, and the start and end moments of each classic Solutrean phase across sites. We conclude that, based on the current data, the traditional organization of the Solutrean cannot be unquestionably confirmed for Southern Iberia, calling into doubt the status of the classically defined type-fossils as precise temporal markers.
