Although true coral reefs have seldom been reported from the fossil record of the Cabo Verde Archipelago, many single fossil corals and coral colonies can be found reworked in tsunami deposits and in raised marine terraces onshore on these islands. This study provides the first detailed survey of fossil corals from 7 of the 10 islands of the archipelago, sampled from Pleistocene marine terraces and tsunami deposits. A total of 168 scleractinian corals were analyzed and identified to genus and/or species level. Thirteen taxa from the families Acroporidae, Dendrophylliidae, Faviidae, Pocilloporidae, Poritidae, and Rhizangiidae were identified. The zooxanthellate fossil corals found on the Cape Verde Archipelago likely migrated from the Caribbean to the West African coast, while azooxanthellate species likely originated from the Indo-Pacific. Differences between present-day coral assemblages and fossil assemblages are assumed to result from changing environmental factors. Although reef-building taxa occur (e.g., Porites), extensive reef frameworks are absent.

Studies of balances (scales) in Europe, Asia and northern Africa have found that their use is not exclusively tied to state control or market exchange, but rather grew and evolved through interactions among bureaucrats in centralized states, merchants, artisans and local leaders. Research on balances from Andean South America can contribute to an understanding of the diverse roles and functions of balances, as they developed independently in a region where there were both exchange-based and non-market economies. This article includes data on Andean balances that reveal that they were used as early as the Late Intermediate Period (ad 1100–1400), and that there is variation in the characteristics and dimensions of the balances. Similar to other regions, balances in the Andes were likely used by different groups of specialists including merchants, bureaucrats and artisans. To understand how balances were used, they need to be understood alongside long-distance exchange practices, socio-political strategies, the organization of craft production and the possible use of currency.

Based on calibrated radiocarbon ages of terrestrial gastropod shells (Succineidae, Discus, Stenotrema, Webbhelix), the chronology of Peoria Silt (loess) deposition in the Central Lowlands is updated. These taxa provide reliable ages (within ~0.2 ka), based on historical shell dating, shell-organic age comparisons, and stratigraphic consistency. A compilation of 53 new and 36 published Peoria Silt shell ages (calibrated), from 12 localities, date from 30.0 to 17.4 ka. Proximal (fossiliferous) loess from 10 sections had mean loess accumulation rates of 0.6–2.2 mm/yr. Study sites along the upper Mississippi, Illinois, to mid-Mississippi, and Ohio-Wabash Valleys suggest Peoria loess accumulated from ~27 to 15 ka, ~29 to 18 ka, and ~30 to 18 ka, respectively. The cessation age for Peoria Silt, based on surface extrapolations, is ~1–6 ka earlier than some prior Illinois estimates, even assuming slower loess accumulation in the modern solum. Younger loess in northwestern Illinois likely reflects, in part, Superior and Des Moines Lobe glacial-meltwater sediment, and Iowan Erosion Surface inputs to the upper Mississippi Valley, after the Lake Michigan Lobe receded. Furthermore, stronger winds, drier conditions, and reduced vegetation cover in valley deflation areas may have favored higher accumulation rates and later loess deposition in northwestern relative to southeastern areas.

High-resolution sedimentological and geochronological investigations of paleochannel systems in the Ried Central d'Alsace (northeastern France) allow for the reconstruction of the late glacial and Holocene fluvial evolution of this section of the Upper Rhine alluvial plain. During the Oldest Dryas, the landscape featured a dominant braided Rhine system and, to a lesser extent, a braided Fecht system. The shift to the Bølling-Allerød saw a narrowing of the Rhine's active channel belt, the development of a complex channel pattern, and the genesis of the Ill River. The river channel patterns remained unchanged during the Younger Dryas. In the Early Holocene, the Rhine's active belt narrowed further, and the Rhine and Ill Rivers developed braided-anastomosing and anastomosing channel patterns, respectively. Throughout the Holocene, both rivers maintained their channel patterns while migrating east and west across the alluvial plain, respectively. In the late glacial, fluvial dynamics in this section of the Upper Rhine plain were primarily influenced by climate-related environmental and hydrogeomorphological changes. Conversely, during the Holocene, the evolution of the fluvial hydrosystems was driven by a complex interaction of climatic and non-climatic factors, including human activity at the catchment scale, alluvial plain architecture, and local neotectonics.

This article explores the decolonization of heritage politics in 1970s Hong Kong. It firstly revisits recent scholars’ work on Hong Kong heritage politics and the transformation of Hong Kong’s cultural identity. It shows how people’s perceptions of their colonial heritage and history in Hong Kong have changed since the 1970s. Secondly, it outlines the city’s cultural heritage policy framework after the 1967 Riots, inspired by the Cultural Revolution. It analyses how the colonial government intentionally rebranded the city’s colonial heritage as an anachronism to justify its new narrative of Hong Kong and its cultural identity in the 1970s. It also employs the demolition of the former Kowloon Railway Station building in the 1970s as a case study to discuss how the colonial government decolonized local colonial structures through its new cultural heritage policy approach after the Riots. Finally, by employing the case study of the demolished Central Star Ferry Pier in the 2000s, this article argues there was a change in people’s perceptions of the city’s colonial history in the early postcolonial period of Hong Kong. A more active notion of Hong Kong’s cultural identity is also being articulated in the uncertain future due to the city’s recent rapid political and social changes influenced by the mainland authority.

Two sediment sections are investigated at Cape Arkhangelos, island of Rhodes, where Pleistocene marine sediments crop out in horsts and grabens of a Mesozoic basement. There, hemipelagic sediments characterized by upper bathyal communities are atypically mixed with much shallower faunal components because they were deposited close to rugged coastal landforms. Biostratigraphic analyses show that the sections were deposited between 1.8 and 0.9 Ma, and between 1.8 and 1.6 Ma, respectively. By combining the planktonic/benthic foraminiferal ratio with 31 bathymetric indicators chosen among extant species of benthic foraminifera, mollusks, and bryozoans, we show that relative sea-level fluctuations can be reconstructed in these atypical settings despite the proximity of steep slopes that favored transportation of allochthonous fauna. The shallow-water components (including gravels and calcareous algae) were transported downslope by the combined action of gravity, currents, and tectonic disturbance that promoted drowning (with a maximum flooding recorded at ca. 1.7 Ma) and then uplift of fault-bounded paleovalleys that formed during the Early Pleistocene. Abrupt facies changes and age differences between sections have been triggered by the irregular paleotopography of the Mesozoic basement, which fostered differential depositional settings, with outer to middle neritic deposits above the horsts and upper bathyal deposits in paleovalleys.

Hobby metal detecting in Norway has grown since 2014. In the Norwegian recording system, all finds are catalogued by professionals at five regional museums. The examination of the dataset thus created allows the authors to look at regional and national patterns and discuss the inherently messy and ‘human’ nature of a seemingly quantitative material. Their study suggests that both archaeologists and detectorists influence the quality of the evidence and how representative the data are. They argue that metal detecting patterns are primarily the result of modern activities, such as management practices and the endeavours of a few very prolific detectorists in certain areas. Understanding these biases and systematically recording the activities of the actors involved is crucial if we are to make full use of the metal-detected material.

Deer hunting was heavily ritualized in medieval Europe, as indicated by historical and archaeological evidence; it also emphasized social differentiation. The butchery of a deer carcass (‘unmaking’) was integral to the ritual and led to different body parts being destined for individuals of differing status. Archaeologically, the practice is particularly visible in high-status sites in Britain, but documentary and archaeological sources are consistent in pinpointing its earliest occurrence in twelfth-century France. In Italy, late medieval evidence for such ‘unmaking’ is present but is not supported by any known historical sources. Red and fallow deer were butchered in a formalized manner, whereas the data for roe deer are unclear. Although the Normans contributed to the diffusion of the ‘unmaking’ practice, in France it is also found outside the core area of Norman influence. The extensive spread of the practice demonstrates the connectedness of the medieval hunting culture in Europe.

The absorption and distribution of radiocarbon-labeled urea at the ultratrace level were investigated with a 14C-AMS biotracer method. The radiopharmaceutical concentrations in the plasma, heart, liver, spleen, lung, kidney, stomach, brain, bladder, muscle, testis, and fat of rats after oral administration of 14C urea at ultratrace doses were determined by AMS, and the concentration-time curves in plasma and tissues and pharmacokinetic distribution data were obtained. This study provides an analytical method for the pharmacokinetic parameters and tissue distribution of exogenous urea in rats at ultratrace doses and explores the feasibility of evaluation and long-term tracking of ultratrace doses of drugs with AMS.

Multiproxy sedimentary sequence analysis constitutes the basis for reconstructions of past paleoenvironments and climate evolution. These sequences are, for the most part, obtained by coring in lakes, maars or crater lakes whose waters can record volcanic activity or karstic contributions, especially in Eastern Anatolia and the Lesser Caucasus. The reservoir age effect in these geological contexts leads to an apparent aging of the radiocarbon ages which also affects the plants and animals developing in or near these waters and consequently the population consuming them. We present here some results obtained from modern samples taken from Mediterranean, central and eastern Anatolian lakes, from the Van and Sevan lakes and along the Kura River and its tributaries from the Lesser Caucasus. The effect of volcanic CO2 outgassing in the vicinity of maar crater lakes is also discussed.
