Land snail shells are usually avoided for radiocarbon dating, due to the possible presence of dead carbon, although measurements on certain small species can be reliable. However, terrestrial gastropods, which are often abundant and well preserved in favorable sedimentary contexts, may represent an important source of material for precise dating. In this study, the shell selection method and radiocarbon results are presented, based on about twenty dates, from well-known and reliable archaeological contexts mostly from the Languedoc (southern France) and covering different cultural periods of the Holocene. Chronological controls are provided by dates based on plant remains, archaeological artifacts and stratigraphy, as well as geomorphological and environmental interpretations. The results obtained based on gastropod shells show a good agreement with the expected dates. In some examples, the target period is quite large, making it difficult to determine the degree of accuracy. However, other tests give perfectly synchronous dates between botanical or archaeological material and mollusks. Species selection takes into account that terrestrial gastropods living in the midst of vegetation are less likely to ingest fossil carbon and are therefore better suited for dating, especially wetland species, Succinella oblonga and Vertigo pygmaea. These promising results show the potential of terrestrial shells for dating archaeological sequences when prevailing biological material such as charcoal is lacking or is unreliable.

Food preservation, including salting and barreling meat, has played a significant role in human history; however, it remains challenging to identify cases of salting in the archaeological record. Most studies have relied on limited datasets and focus on body-part profiles observed in faunal assemblages. Known and suspected cases of barreled meat and on-site butchery, drawn from six shipwrecks and seven fur trade posts, provide a means of identifying body-part profiles for salted pork and beef. Modeled body-part profiles based on these data reveal differences in expected body-part frequency between salted and locally butchered beef, although the patterning is less obvious for pork. Comparing these models against 26 military forts reveals that, despite the prominence of salted beef and pork in historic records, many forts exhibit patterns consistent with on-site butchery of live animals.

Five unknown Holocene flank eruptions from the Masaya caldera are reported here. These eruptions comprise basaltic lava flows emplaced in Masaya’s northern rift zone along the Cofradía fault zone, east of Managua City. The lava flows were defined as Mosintepe, Portillo, Gorgonia, Campuzano, and Martha units. Paleosol samples were collected below each lava flow, and radiocarbon AMS analyses were performed, yielding ages of 2250 ± 30, 1610 ± 30, 1600 ± 30, 1140 ± 30, and 790 ± 30 yrs BP, respectively. Calibrated age intervals are 285–229 cal BC for Mosintepe, 496–534 cal AD for Portillo, 496–535 cal AD for Gorgonia, 914–976 cal AD for Campuzano, and 1226–1268 cal AD for Martha; all stratigraphically consistent. These eruptions emitted magma bulk volumes between 0.02 and 0.51 km3, reaching up to 8 km from their eruptive vent and 13 km from Masaya’s polygenetic system summit crater. Their mineral paragenesis, and major and trace element geochemical fingerprint reveals a common volcanic provenance from the Masaya caldera due to lateral magma draining. This study demonstrates that basaltic lava flow flank eruptions are common in the Masaya caldera along its northern volcanic rift zone. Therefore, this information should be considered in future hazard and risk assessments.

The green tree python is quite a favorite pet for sale on the international market. The species is therefore protected by the Convention on International Trade in Endangered Species of Wild Flora and Fauna (CITES). Since the illegal poaching of large numbers of specimens in the wild might lead to the detriment of native populations, and wildlife breeding farms were found to be serving as conduits to funnel wild-caught green tree pythons out of Indonesia, a forensic tool to distinguish wild-caught from captive-bred specimens could support the enforcement of CITES protections. To disrupt the illegal trade of green tree pythons, we have developed an effective tool to distinguish the animals supposedly bred in captivity from those caught in the wild, based on the strontium isotope composition in conjunction with trace element data. Like in human hair, 87Sr/86Sr values seem to vary according to the relative contribution of endogenous and exogenous sources. Thus, we infer that if there is enough sustainable strontium available for the analysis, it might be possible to use the 87Sr/86Sr values in parallel with trace elements to distinguish wild-originated specimens from the in captivity-bred ones. Indeed, our pilot study on the shed skins of animals where the geographic origin was either the Czech Republic or Indonesia, confirms that shed skins can be effectively used for further forensic Sr radiogenic isotope analyses.

This paper presents the results of recent geophysical survey work in the vicinity of the Roman town of Isurium Brigantum (Aldborough, North Yorkshire). It combines results from research projects with information from developer-funded work to assess the nature of settlement in the area at the time of the foundation of the Roman town and through the period of its use. The work confirms that there was no major pre-Roman Iron Age centre in the area at the time of Roman annexation. It does, however, provide new evidence to show that the landscape was heavily exploited and occupied by rural settlements. The evidence revealed suggests that Iron Age society in this area may have been heterarchical.

This paper anatomises and illustrates drawings and prints in the British Museum extracted from an early seventeenth-century album. The drawings, which were inserted by the museum into a new album, suggest that the original album originated in the workshop of a London goldsmith with German or central European origins who worked for the royal court and had a connection to Thomas Cecil, Earl of Exeter. Particular attention is paid to forty-four ornament prints, mainly German, long separated from the drawings. Nearly all are signal additions to the canon of engraved ornament documented in London at this early date. The ensemble thus reassembled is a rare window into design sources, style and processes early in the Stuart period.

A recent fluorescence of geophysical and archaeological research in Catholic cemeteries illustrates the benefits and challenges of community-engaged projects. Focusing on four ongoing case studies in coastal Virginia and Maryland (the Chesapeake region)—St. Mary’s Basilica (Norfolk, Virginia); Brent Cemetery (Stafford County, Virginia); Sacred Heart Church (Prince George’s County, Maryland); and St. Nicholas Cemetery (St. Mary’s County, Maryland)—this article explores a variety of archaeological strategies in the context of community engagement. These approaches are shaped by the physical characteristics of cemetery sites, the Catholic diocesan or church communities that oversee them, and the African American descendant communities affected by them. The built environment of cemeteries highlights the way that racism and segregation have shaped both the landscape and public memory of Catholic cemeteries in the Chesapeake region.
