- Southern Portugal animal exploitation systems: trends and changes from Neolithic to Bronze Age. A follow-up overviewPublication . Valente, Maria João; Carvalho, AntónioZooarchaeological studies in Neolithic, Chalcolithic and Early Bronze Age Portugal have witnessed important developments in recent years, even if still largely based on taxonomic analyses. Other approaches depend heavily on the abundance and preservation conditions of faunal collections, which are often inadequate
- Multi-isotope approaches to the Neolithic cemetery-cave of Bom Santo (Lisbon): new data and comparisons with fourth millennium BC populations from central-southern PortugalPublication . Carvalho, AF; Gonçalves, David; Bonilla, Marta Diaz-Zorita; João Valente, MariaPrevious multi-isotopic research on the human remains of the Neolithic cave-cemetery of Bom Santo (Lisbon, Portuguese Estremadura) led to the conclusion that this fourth millennium BC population was very heterogeneous at several levels. Two in particular were subsistence habits and mobility: although consumption of terrestrial foods was the norm, aquatic food sources totalling > 20% of overall diets were detected in 60% of the population, and, surprisingly, 79% of the individuals were classed as non-local, having lived most of their life in geologically older regions. These figures were however obtained on a sample of 15 individuals. Further isotopic analyses have enlarged the original sample to 35 individuals (i.e., half of the exhumed population) and were also employed in the study of the coeval cave-cemeteries of Barrao and Mureta. This has permitted a sounder depiction of past behaviours, with a structural difference being observed at both levels between Bom Santo and the latter sites: at the former cave, 70% of the population consumed > 20% of aquatic foods and 34% were non-local (23% from outside Estremadura), whereas the latter were all local and showed no signals of aquatic diets. Comparison with other fourth millennium BC populations in central-southern Portugal suggests a model where the exploitation of locally available aquatic/marine food sources was not mandatory but optional and that human mobility represented an important socio-economic behavioural feature of these (presumably) segmentary societies. How both aspects related to the then-emerging megalithic phenomenon is a question that should be investigated in future research.
- Individual vessels, individual burials? new evidence on early neolithic funerary practices on the Iberian Peninsula's western façadePublication . Cardoso, João Luís; Carvalho, AF; Rebelo, Paulo; Neto, Nuno; Simões, CarlosDespite previous attempts, the Early Neolithic of Portugal was poorly understood until the latter part of the twentieth century. It is only when Guilaine and Ferreira (1970) re-analysed pottery assemblages kept in museums across the country and compared them with parallels elsewhere in Iberia and southern France that they were able to distinguish between an earlier Cardial phase and a more recent stage, named ‘Furninha horizon’ after an important burial cave excavated in 1880. Essentially, most Portuguese prehistorians still use this scheme today. Though some have argued in favour of pre-Cardial phases, either of African or Andalusian origin (e.g. Silva & Soares, 1981) or represented by impressa-type ceramics of Italic origin (e.g. Guilaine, 2018), these hypotheses are still lacking sound empirical support (Carvalho, 2020). It should, however, be noted that these hypotheses are still sometimes taken up in discussions of new finds. This is the case in a recently-published ovoid vase, with a flat base and impressed decoration, retrieved from so-called ‘hearth 8’ at the open-air site of Vale Pincel (coastal Alentejo), which was dated to c. 5650 cal BC. As this predates the oldest Cardial in Portuguese territory and is not a Cardial vessel, the author claims that this ‘ceramic decoration is part of the pre-Cardial impressed world’ (Soares, 2020: 311–2 and fig. 4).
- NeoNet Atlantic. Radiocarbon dates for the late mesolithic/early neolithic transition in the Southern European Atlantic CoastPublication . Huet, Thomas; Basílio, Ana Catarina; Faustino de Carvalho, António Manuel; Cubas, Miriam; Gibaja, Juan F.; López-Romero, Elías; Oms, F. Xavier; Mazzucco, NiccolòNeoNet Atlantic dataset complements the NeoNet Mediterranean dataset by providing new curated radiocarbon dates for the study of the pioneer farming front (i.e. Neolithisation, ca. 7500 to 3500 cal BC) in the Southern European Atlantic Coast river basin (Portugal, Western Spain, Southwestern France). The complete dataset is formed by the id00164_doc_elencoc14.tsv file, a data frame with tab -separated values, and a related dataframe: id00164_doc_thesaurus.tsv. The dataset contains 1,143 radiocarbon dates from 254 archaeological sites and 817 different archaeological contexts (stratigraphic units, structures, negative features, hearths, etc.) informed by 233 bibliographical references. As for the NeoNet Mediterranean dataset, particular attention has been paid to homogenisation of the laboratory code, the archaeological context, and the references, in order to facilitate further data extractions. Indeed, the dataset is linked to an open source R Shiny interactive web app (NeoNet app), a series of functions hosted on GitHub, and a getter function (R package c14bazAAr, R function get_c14data("neonetatl").
