Late Silurian and Early Devonian biostratigraphy in the Hill End Trough and the Limekilns area,New South Wales

Precordilleran Late Palaeozoic brachiopod genera considered for this palaeobiogeographical analysis belong to four faunal associations: the low diversity Early Carboniferous (Tournaisian) Protocanites scalabrinii-Azurduya chavelensis Zone; the Late Carboniferous (Bashkirian-Moscovian) Levipustula fauna, which appears in sequences associated with glacial intervals; the latest Carboniferous-earliest Permian (Gzhelian-Asselian) Rhipidomella-Micraphelia and Tuberculatella-Aseptella associations, and the Early Permian (mid to late Asselian) Tivertonia jachalensis-Streptorhynchus inaequiornatus Biozone. The brachiopod affinities of the Precordillera are compared with the biogeographical Late Palaeozoic regions previously suggested by other authors using cluster analysis. During the Bashkirian-Moscovian, the Precordilleran faunas show a high affinity with the Austral Realm because of the presence of the Levipustula faunal elements in Eastern Australia. At the same time the affinity with the central and North American Regions is very low. The Early Permian Precordilleran faunas demonstrate highest affinity with the Gondwanan Realm with several genera also linked to the Tethyan and Boreal Realms. After the Late Carboniferous glacial episodes that affected the southwestern Gondwanan margin, the Precordilleran region underwent climatic amelioration. Subsequently, the Early Permian Precordilleran brachiopod assemblages are characterized by typical cool to cold water genera widely developed in the core Gondwanan Realm, with fewer genera (such as Kochiproductus, Rhynchopora and Neochonetes) suggesting a warmer water influence. The Precordilleran faunas demonstrate an increase in brachiopod diversity from the Carboniferous to the Permian, related to water temperature changes and to the palaeogeographical evolution of the southwestern Gondwanan margin and the movement of Gondwana across the South Pole.     

Facilitating Interaction: Board Games as Social Lubricants in the Ancient Near East

This re‐evaluation of existing data on board games from the Near Eastern Bronze Age demonstrates their function as social lubricants in cross‐cultural interaction. Board games are situated theoretically as liminoid practices, which lie outside the bounds of normative social behaviour and allow for interaction across social boundaries. Utilizing double‐sided game boards, with an indigenous game on one side and a newly introduced game on the other, the games of senet, mehen and twenty squares provide evidence for social interactions. Cypriots had adopted Egyptian mehen and senet by the third millennium BC, and indigenized the games. This lies in contrast to the game of twenty squares, which had a particular role among elites in the Late Bronze Age interaction sphere. This anthropological discussion of evidence relating to gaming seeks to inspire further research on the role of board games in society.     

“Wilderness” revisited: Is Canadian park management moving beyond the “wilderness” ethic?

This paper questions whether the rescaling of conservation practice in Canada to include local and Indigenous communities, NGOs, and private market-based actors represents a move away from wilderness-thinking in conservation, and what implications this might have for the future of conservation in Canada. We explore the links between Cronon's “wilderness” ethic and coloniality, racism/sexism/classism, and political economy, and the extent to which recent trends in conservation practice, such as co-management arrangements, private tourism proposals, and a shift in programming to attract a diverse public to parks, help us to move beyond the limited vision for conservation and environmentalism that the wilderness ethic provides. We interrogate the ways in which the concept of wilderness is being employed, resisted, and transformed by a multitude of actors in three parks and conservation areas across Canada. We argue that although recent developments in conservation practice help to redress some of the worrisome aspects of wilderness-thinking in parks, they also reinforce and re-emphasize problematic lines of thinking and praxis. While the wilderness character of Canadian parks has shifted a great deal since the turn of the 20^th century, the wilderness ethic remains deeply embedded within conservation discourse and practice.     

Reflections on Collaborative Archaeology and Large-Scale Online Research Infrastructures

ABSTRACT

The Archaeology Data Service (ADS) is an archive working at a national level in the UK, ensuring that archaeologists have access to high quality and dependable digital resources, including openly licensed legacy data for reuse. The ADS acts as a metadata aggregator for archaeological data held by larger heritage agencies and smaller regional organizations and participates in international aggregation infrastructure projects such as ARIADNE, which allows users to access archaeological resources held in many countries from a single interface. Large-scale infrastructures can facilitate the building of long-term, complex relationships and active collaborations, not just technical solutions. This paper reflects on the roles of stewardship and equity within ARIADNE and the ADS, two large-scale online research infrastructures, and how these types of infrastructures may help to create a more collaborative archaeology, including lessons learned, challenges and opportunities, and thoughts for the future.     

From Traditional Farming in Morocco to Early Urban Agroecology in Northern Mesopotamia: Combining Present-day Arable Weed Surveys and Crop Isotope Analysis to Reconstruct Past Agrosystems in (Semi-)arid Regions

ABSTRACT

We integrate functional weed ecology with crop stable carbon and nitrogen isotope analysis to assess their combined potential for inferring arable land management practices in (semi-)arid regions from archaeobotanical assemblages. Weed and GIS survey of 60 cereal and pulse fields in Morocco are combined with crop sampling for stable isotope analysis to frame assessment of agricultural labour intensity in terms of manuring, irrigation, tillage and hand-weeding. Under low management intensity weed variation primarily reflects geographical differences, whereas under high management intensity fields in disparate regions have similar weed flora. Manured and irrigated oasis barley fields are clearly discriminated from less intensively manured rain-fed barley terraces in southern Morocco; when fields in northern and southern Morocco are considered together, climatic differences are superimposed on the agronomic intensity gradient. Barley δ¹³C and δ¹⁵N values clearly distinguish among the Moroccan regimes. An integrated approach combines crop isotope values with weed ecological discrimination of low- and high-intensity regimes across multiple studies (in southern Morocco and southern Europe). Analysis of archaeobotanical samples from EBA Tell Brak, Syria suggests that this early city was sustained through extensive (low-intensity, large-scale) cereal farming.
