Selecting and Sampling Shipwreck Timbers for Dendrochronological Research: practical guidance

In this article, we provide practical and straightforward guidance for the selection and sampling of shipwreck timbers for dendrochronological research. We outline sampling strategies and present informative figures that illustrate how to proceed in a variety of scenarios that archaeologists regularly encounter. However, in order to fully exploit the potential of tree‐ring research on these objects, we would urge archaeologists to involve dendrochronologists during the project planning phase to carefully plan and conduct adequate sampling of shipwreck assemblages.     

An Overview of Maritime Archaeological Research of the Colonial Period in the French Antilles

This article provides a summary of the various maritime archaeology projects undertaken in the French Antilles (Guadeloupe and Martinique) since the 1980s that date to the 17th–19th century Colonial period. These projects are presented in the context of the principal maritime archaeological research questions. The results are analysed thematically touching on different aspects of archaeological research in littoral and underwater zones: coastal plantations, ports, and micro‐islets. Research carried out on wreck‐sites is presented with respect to their maritime use (commercial, naval, and cabotage). The nature and distribution of such sites provides information both on maritime routes and traffic, trade, conflicts, and environmental risks specific to the Antilles in the Colonial period.     

Sewn Boats of Southeast Asia: the stitched‐plank and lashed‐lug tradition

This article updates research into the sewn‐boat traditions of Southeast Asia with recent finds that provide evidence of the transition from stitched planks with lashed‐lug frames to planks fastened with dowels and locked dowels alongside lashed‐lug frames. The differences between Southeast Asian, East Asian, and Indo‐Arabic boatbuilding are discussed and the meaning of anomalies, such as the Maldivian dhonis, examined. Considering the known history of trade and exchange throughout the South China Sea and the Indian Ocean, the lack of hybridization between boatbuilding traditions is noted.     

Integrated Analytical Techniques for the Study of Colouring Materials from Two Megalithic Barrows

We have determined the composition of rock art pigments from two megalithic barrows located in the north of Portugal. The use of XRD, SEM–EDS and FT–IR spectroscopy confirmed the presence of hematite and kaolinite in the red pigments from the Eireira barrow, and kaolinite in the white pigment from the Leira das Mamas barrow. The organic composition of the pigments was studied by GC–MS, suggesting that the red sinuous lines and dots from the Eireira barrow were prepared with cooked or heated algae and/or aquatic plants, with egg as binder, while the white pigment from the Leira das Mamas barrow revealed a mixture of vegetable oils for kaolinite moulding, which could be stabilized by temporary exposure to high temperatures. The multi‐analytical approach used on this study of megalithic pigments allowed the recovery of important data about north‐western prehistoric communities, namely the way in which they exploited existing resources and their ability to transform them.     

Full‐Vector Archaeomagnetic Dating of a Medieval Limekiln at Pinilla Del Valle Site (Madrid,Spain)

Archaeomagnetic dating based on the full geomagnetic field vector was carried out on a limekiln excavated at Pinilla del Valle archaeological site (Madrid, Spain). The limekiln tradition in this area is largely documented by historical sources for recent centuries but the date of the studied kiln's last use was unknown. The combination of mean archaeomagnetic directional and absolute archaeointensity results shows that the kiln was last used between ad 1296 and 1413, in good agreement with two independent radiocarbon dates. This study provides the first archaeomagnetic evidence that the local limekiln tradition dates back to at least late medieval times. Furthermore, the inclusion of these data in the Iberian secular variation curve and geomagnetic field models will help to improve the archaeomagnetic dating technique.     

New analytical methods for comparing bone fracture angles: A controlled study of hammerstone and hyena (Crocuta crocuta) long bone breakage

Accurate interpretation of the cause and timing of bone breakage is essential for understanding the archaeological record. However, many variables potentially influencing break morphology have yet to be systematically explored. Focusing primarily on hammerstone breakage, we introduce new analytical methods for comparing fracture angles using the absolute values of the angle from 90°. We systematically control for intrinsic variables such as taxon, skeletal element, limb portion and skeletal age. We also compare experimental assemblages of femora broken by hammerstone and spotted hyena (Crocuta crocuta). We show that fracture angles are influenced by breakage plane, skeletal element and limb portion. While the latter two have been suggested before, this is the first time the differences have been quantified. We suggest that researchers stratify their assemblages by these variables if they are using fracture angles in analyses. At the assemblage level, hyenas created more oblique fracture angles on oblique breaks than did hammerstones.     

No Place for the Political: Micro‐Geographies of the Paris Climate Conference 2015

Building upon post‐foundational political philosophies, this article scrutinizes the Paris Climate Conference in December 2015 from a micro‐geographical perspective. The analysis suggests that three different spaces exist at the site of the summit and reveals how their constituting practices and material arrangements rendered “Paris” post‐democratic. We begin with exposing the staged statements of the world's political elites in the meticulously orchestrated Leaders Event as different phenotypes of the post‐democratic condition. We then investigate the formal negotiations in the cordoned‐off backrooms, where positions within the system were at stake, but not the system as such. Finally, we wander through the strictly policed “trade fair” and unveil attempts to entice delegates into techno‐managerial solutions to the climate crisis. In the conclusion, we ponder over the prospects of environmental activism at the COPs in the light of their massive depoliticization.
