The Bell Beaker site near Brodek u Prostějova (Czechia) has yielded remains of a large timber construction accompanied by four symmetrical ritual deposits with numerous artefacts, including more than fifty ceramic vessels. Their decoration consists of incised patterns, in nineteen cases with preserved white inlaid incrustations. To investigate the social relations at this extraordinary site, a multi-analytical and micro-destructive approach was employed to determine the provenance and technology of the pottery and the composition of the white incrustations. The results indicate various origins for the pottery within the region and the presence of extra-regional fabrics and graphitic temper. The main raw materials for the white inlays were calcium carbonate (calcite), hydroxyapatite (bone), and bright clay. The mixing of decorative motifs and the variation in the shape and size of the beakers suggest unique manufacturing processes. These results lend support to the monumental site of Brodek serving as a ritual place for several communities from both local and wider areas.

Results of radiocarbon (14C) analysis of a tree-ring series from Bratislava, Slovakia, covering the period from 1970 to 2004 are presented. For a part of this time period, monthly 14C measurements of atmospheric carbon dioxide from Bratislava sampling station are compared with the tree-ring results. The effects of fossil CO2 emissions on 14C levels in the environment are emphasized by comparison with atmospheric clean air reference values (Schauinsland, Germany). The presented results from Bratislava are also set against the previously measured tree-ring series from Low Tatras mountain region in Slovakia, representing regional clean air radiocarbon levels in the biosphere. The observed 14C levels of Bratislava tree rings and atmospheric CO2 in 1970s and 1980s are significantly lower than clean air data, indicating severe fossil CO2 pollution in Bratislava during this time period.

Marble provenance studies in archaeology have become increasingly popular in recent decades. This has resulted in a large quantity of analytical data becoming available for archaeological marbles. This article presents the results of a quantitative study of the distribution of white marble in the Mediterranean based on an analysis of the available provenance data for the Roman period. The study shows increased distribution of white marble between the late 1st c. BCE and the end of the 2nd c. CE. A decline in distribution from the 3rd c. CE was less abrupt than traditionally believed and shows object-, material-, and region-specific trajectories. The marble distribution data is finally evaluated within a wider socio-economic frame, considering factors such as the marble trade system and broader Roman economy, changes in cultural practices related to statue erection, importance of reuse and recycling, growing ruralization, and reduced interest of the elite in urban capital investment in the later Roman periods.

Stable isotopes have been used historically to track food webs. Our approach used a combination of δ13C and radiocarbon (14C) dating to identify carbon sources in cave shrimp within caves of the Karstic Yucatan Peninsula, Mexico. Three sister species of stygobitic Typhlatya shrimps were collected from the cenote pool (cenote hereafter), cavern and cave hydro regions. New and previously reported 14C and δ13C values of whole tissues from the organisms were determined at the AMS laboratory (LEMA) of the Institute of Physics of the Universidad Nacional Autónoma de México. This new set of isotopic values of biomass and potential sources were incorporated into the Bayesian Mixing Modeling Software SIAR. In two hypothetical scenarios, the contribution from each feeding source among three species of the Typhlatya genus was determined. Slight differences were also observed between isotopic values of two groups of the same species collected in two distant cenote pools, suggesting this species may feed on a wider array of sources than previously found, and that the oligotrophic environment may have a strong influence on cave shrimp diet.

In urban environments, diachronic evolution of water quality can be reconstructed using geochemical analysis of urban secondary carbonate deposits (USCDs), from urban underground structures, similar to speleothems from natural caves. The use of the radiocarbon bomb peak to build their precise chronology was recently tested in two Paris-area urban sites (France). In this study, new samples from contrasted environments in the Paris region were sampled in order to test the sites’ effects on the radiocarbon signal recorded: under wood, under a fountain, in underground aqueducts, in the south and north of Paris. We compared the post-bomb atmospheric radiocarbon record with the one measured at the top of USCDs, and estimated the dead carbon proportion (DCP), between 0 and 40%. USCDs fed by water with a rapid transfer through thin soil (Versailles fountain) had the lowest DCP (14C very close to atmospheric one). Highest DCP were found for USCD from deep underground quarry under urban wood, and intermediate ones for USCDs fed by the waters of perched aquifers. These data support the use of radiocarbon as chronometer for USCDs in contrasted urban contexts, and show that it can be used to determine carbon transport and sources, an important parameter for pollution reconstruction.

Wasted tires are the great source of fuel and valuable components but could be a cause of environmental and land pollution. This study shows the detailed method for the determination of radiocarbon isotope (14C) concentration in tires and their pyrolysis products. Samples are taken from truck and passenger car tires in the form of shredded rubber, pyrolysis oil and recovered carbon black. Liquid scintillation counting (LSC) and accelerator mass spectrometry (AMS) techniques were used for the investigation at Gliwice Radiocarbon and Mass Spectrometry Laboratory, and National Laboratory for Age Determination, Trondheim, Norway. The results are in good agreement. Radiocarbon concentration of the rubber varies significantly because of its complex structure and composition within the tires. The 14C concentration values were found to be higher in pyrolytic oil compared to rubber, and greater in truck tires rather than car tires.

The tomb of Marcus Venerius Secundio was discovered in July 2021 in the necropolis of Porta Sarno at Pompeii. This paper contextualizes it against the backdrop of 1st-c. CE burial customs and social history. The inscription on the pediment shows that the tomb owner was a former public slave who, after manumission, rose to the rank of the Augustales; he was a “custodian” of the temple of Venus, and he organized “Greek and Latin games/performances.” This is the first archaeological discovery providing direct evidence of Greek musical and/or theatrical performances at Pompeii. Another peculiarity is that Secundio was inhumed, not cremated, a practice so far unique among adults in Pompeii during this period. The inhumation of Secundio and his titulus sepulcralis can be read as local reflections of the Neronian zeitgeist and shed light on the modes by which cultural trends spread from the capital throughout the empire.
