In order to better characterise carbonaceous components in atmospheric aerosols and to assess the contributions of fossil carbon (FC) and non-fossil carbon (NFC) sources and their seasonality in the Eastern Mediterranean, we collected fine (PM1.3) aerosols at a remote marine background site, the Finokalia Research Station, Crete, Greece, over a period of one-year. PM1.3 samples were analysed for elemental carbon (EC), organic carbon (OC), water-soluble OC (WSOC), and stable carbon isotope ratio (δ13CTC) and radiocarbon content (14CTC) (pMC) of total carbon (TC). All the parameters, i.e., PM1.3, δ13CTC and 14CTC showed a clear temporal pattern with higher values in summer and lower values in autumn. The 14CTC ranged from 54.7 to 99.1 pMC with an average of 74.5 pMC during the entire year. The FC content in TC (FCTC) was found to be slightly lower in winter and almost stable in other seasons, whereas the NFC contents (NFCTC) showed a clear seasonality with the highest level in summer followed by spring and the lowest level in winter. Based on these results together with the seasonal distributions of organic tracers, we found that biomass burning (BB) and soil dust are two major sources of the fine aerosols in winter. Although biogenic emissions of VOCs followed by subsequent secondary oxidation processes are significant in summer followed by spring and autumn, pollen is a significant contributor to TC in spring. This study showed that emissions from fossil fuel combustion are significant (25.5%) but minor compared to NFC sources in the eastern Mediterranean.

We appreciate the respondents’ comments on our debate article ‘Cultural evolution as inheritance, not intentions’ (Bentley & O'Brien 2024). We all agree that traditional cultural practices—such as manufacturing Acheulean handaxes—often take considerable amounts of time to learn; as Gladwell (2008) popularly proposed, it takes 10 000 hours of practice to make an expert. We also appear to agree that cultural practices are intergenerational. As Frieman (2024: 1421) notes, ideas and practices persist because they are “valued, recreated, manipulated, instrumentalised and enacted generation after generation”; and as Ingold (2024: 1417) puts it, traditional tasks “are not subject to the free will of the individual but fall upon practitioners as part of their responsibilities” to their communities. Drawing on the practice of Bronze Age metallurgy, Pollard (2024) asks the million-dollar questions: how does innovation occur, and what causes it? As both Prentiss (2024) and Pollard note, for example, the pace of technological change is often punctuated, an observation common across the natural and social sciences, but one that defies easy explanation (e.g. Duran-Nebreda et al. 2024; O'Brien et al. 2024).

The Second International Mortar Dating Intercomparison Study (MODIS2) took place in 2020. Three mortar samples from different sites and chronologies were distributed among various research groups in form of bulk mortar and grain fraction smaller than 150 µm. This is the first time the Zagreb Radiocarbon Laboratory, with support of the Center of Applied Isotope Studies, University of Georgia, took part in the international mortar intercomparison. The initial approach of the Laboratory to mortar dating was to separate 32–63 µm grain fraction and collect three CO2 gas portions by sequential dissolution with acid. After checking the 14C date trends of the gas portions, which should be ascending with later fractions, the one for the first and shortest gas portion was reported as the age of the mortar. However, the first gas portion might not be true age of the mortar, since it still might contain some “dead” carbon. Therefore, data extrapolation from the first two initial CO2 portions was also conducted on the results, but not reported to the intercomparison. Though in general, all the intercomparison reported dates fit the expected historical ages, for one sample, the extrapolated result showed a better match to the historical data.

We present the excavation results from a Middle Neolithic site associated with the Funnel Beaker Culture. Within two overlying house phases, a recessed area was recorded, which had been constructed using different sized pebbles. The arrangement and form of the feature clearly indicated anthropogenic origin and is understood as belonging to one of the house phases. Consequently, it is interpreted as a cellar. Several pits and post holes are additional features that were recorded at the site and indicate the presence of a fence structure with up to seven parallel courses. In this paper, we present radiocarbon dates from the features and an age model for the construction and use of the cellar as well as the fences. Moreover, the site Nygårdsvej 3 will be placed in its regional archaeological landscape.

For many years, scholars consistently dated cup marks – shallow depressions found on both portable and immovable stones – of northern Germany and southern Scandinavia to the Bronze Age. Novel findings trace them back to at least as far as the Late Neolithic period (LN, c. 2350 bc). Recently, portable cup marked stones belonging to a late Funnel Beaker context (c. 2800 bc) have been found. There are even indications of cup marks dating back to the 4th millennium bc. At present, a gap exists in the knowledge of cup marks and non-figurative art in general during the Younger Neolithic (YN) Corded Ware Culture (CWC) (c. 2800–2250 bc). This paper establishes the significance of three related types of secondary treatments of battle axe fragments, namely the addition of (hourglass shaped) unfinished shaft holes, deep pecking holes, and shallow cup marks. The argument put forward is that they were present in small numbers in the 4th millennium bc, becoming increasingly common during the proposed ‘gap phase’ in the context of CWC societies. The late 3rd millennium is a period of enormous social change. During this period, of the three types of secondary treatment only cup marks persist, while the potential media on which such cup marks are applied diversifies, with them appearing on objects and items other than battle axe fragments. It is proposed that this development is related to the social changes that characterise the onset of the LN. Finally, it is suggested that the LN and Bronze Age cup mark tradition is based on an earlier tradition initially associated with battle axes.
