A Scottish provenance for the Altar Stone of Stonehenge
Anthony Clarke et al.
Nature, 15 August 2024, Pages 570-575
Abstract:
Understanding the provenance of megaliths used in the Neolithic stone circle at Stonehenge, southern England, gives insight into the culture and connectivity of prehistoric Britain. The source of the Altar Stone, the central recumbent sandstone megalith, has remained unknown, with recent work discounting an Anglo-Welsh Basin origin. Here we present the age and chemistry of detrital zircon, apatite and rutile grains from within fragments of the Altar Stone. The detrital zircon load largely comprises Mesoproterozoic and Archaean sources, whereas rutile and apatite are dominated by a mid-Ordovician source. The ages of these grains indicate derivation from an ultimate Laurentian crystalline source region that was overprinted by Grampian (around 460 million years ago) magmatism. Detrital age comparisons to sedimentary packages throughout Britain and Ireland reveal a remarkable similarity to the Old Red Sandstone of the Orcadian Basin in northeast Scotland. Such a provenance implies that the Altar Stone, a 6 tonne shaped block, was sourced at least 750 km from its current location. The difficulty of long-distance overland transport of such massive cargo from Scotland, navigating topographic barriers, suggests that it was transported by sea. Such routing demonstrates a high level of societal organization with intra-Britain transport during the Neolithic period.
Human dispersal and plant processing in the Pacific 55 000–50 000 years ago
Dylan Gaffney et al.
Antiquity, forthcoming
Abstract:
The dynamics of our species’ dispersal into the Pacific remains intensely debated. The authors present archaeological investigations in the Raja Ampat Islands, north-west of New Guinea, that provide the earliest known evidence for humans arriving in the Pacific more than 55 000–50 000 years ago. Seafaring simulations demonstrate that a northern equatorial route into New Guinea via the Raja Ampat Islands was a viable dispersal corridor to Sahul at this time. Analysis of faunal remains and a resin artefact further indicates that exploitation of both rainforest and marine resources, rather than a purely maritime specialisation, was important for the adaptive success of Pacific peoples.
Representations of calendars and time at Göbekli Tepe and Karahan Tepe support an astronomical interpretation of their symbolism

Time and Mind: The Journal of Archaeology, Consciousness and Culture, July 2024
Abstract:
Göbekli Tepe, an archaeological site in southern Turkey, features several temple-like enclosures adorned with many intricately carved symbols. It is located centrally among a group of Taş Tepeler pre-pottery Neolithic sites which include Karahan Tepe and Sayburç. Here, an earlier astronomical interpretation for Gobekli Tepe’s symbolism is supported and extended by showing how V-symbols on Pillar 43 in Enclosure D can be interpreted in terms of a lunisolar calendar system with 11 epagomenal days, which would make it the oldest known example of its type. Furthermore, it is shown how Göbekli Tepe’s 11-pillar enclosures and a megalithic 11-pillar pool structure at nearby Karahan Tepe can also be interpreted in terms of the same lunisolar calendar system. Other V-symbols at Göbekli Tepe are also interpreted in astronomical terms, and it is shown how the Urfa Man statue, a wall carving at Sayburç and a statue at Karahan Tepe that display V-symbol necklaces can be interpreted as time-controlling or creator deities. Symbolic links with later cultures from the Fertile Crescent are explored. Throughout, links are made with the Younger Dryas impact and Cauvin’s theory for the origin of the Neolithic revolution in the Fertile Crescent.
Isotope and morphometrical evidence reveals the technological package associated with agriculture adoption in western Europe
José Araus et al.
Proceedings of the National Academy of Sciences, 6 August 2024
Abstract:
This study aimed to reconstruct the environmental conditions and the crop management practices and plant characteristics when agriculture appeared in western Europe. We analyzed oak charcoal and a large number of cereal caryopsides recovered from La Draga (Girona, Spain), an early (5300 to 4800 cal. BC) agricultural site from the Iberian Peninsula. The carbon isotope discrimination (Δ13C) values of oak, the dominant forest species in the region, indicates prevalence of a wet climate at the site. Further, we reconstructed crop management conditions, achievable yield, and crop characteristics through the analysis of Δ13C, nitrogen isotope composition (δ15N), nitrogen content, and the reconstructed weight of wheat and barley caryopsides, following protocols developed by our team [Araus et al., Nat. Commun. 5, 3953 (2014)] and comparison of these parameters with present-day organic agriculture in the region. In parallel, a regional perspective was achieved through the study of wheat and barley grains of seventeen Neolithic sites from the western Mediterranean. The results suggest that rather than small-garden cultivation, a more extensive agriculture was practiced under good water availability and moderate manuring. Moreover, results from La Draga evidence that grain weight and spike morphology were comparable to contemporary cereals. Growing conditions and the prevalence of improved crop traits indicate that agriculture was fairly consolidated at the time it reached the western edge of Europe.
The Establishment of the Agricultural Landscape of Central Sicily Between the Middle Neolithic and the Beginning of the Iron Age
Claudia Speciale et al.
Human Ecology, April 2024, Pages 229–253
Abstract:
The possible co-variation of human occupation and vegetation from the Middle Neolithic to the beginning of the Iron Age (7.5–2.8 ka BP) in Central Sicily in the context of the central Mediterranean between Middle and Late Holocene are analysed in this paper to provide new insights on Sicilian prehistoric demography. The demographic and economic trends during these millennia were reconstructed using archaeological, Accelerator Mass Spectrometry 14C dates, palynological, archaeobotanical, and zooarchaeological data from the northern, central, and southern sectors of Central Sicily through a diachronic comparison with variation in Arboreal Pollen, Anthropogenic Pollen Indicators, Olea-Juglans-Castanea pollen, microcharcoals, and Sporormiella from four pollen cores from sites in different ecosystems. A very significant spread of farming activities was found at the end of the Neolithic, together with an apparent demographic gap during the Middle Copper Age, and the emergence of agricultural landscapes at the end of the Copper Age associated with a striking increase in population. A combination of cultural and climatic changes during the late phase of the Bronze Age resulted in a subsequent overall decrease in population.
