Archaeologists keep a limited arsenal of methods for dating stone features at alpine sites. Radiocarbon (14C) dating is rarely possible, and it is common that dates do not accurately represent the activity of interest (stone feature construction). In this paper I review a legacy set of 89 14C dates for stone driveline sites built by hunter-gatherers in Colorado’s Southern Rocky Mountains. I amend the sample of dates using chronometric hygiene and focus on dates with direct association to hunting features. I then present a newly calibrated set of 29 lichenometric dates for rock features at these sites and use hygiene protocols to remove inaccurate dates. Size-frequency lichenometry, though poorly known in archaeology, provides a way to date stone features indirectly by measuring the growth of long-lived lichens that colonize rock surfaces after construction events. Bayesian modeling of the combined set of dates suggests that the tradition of alpine game driving spans over 6000 years BP, with abundant use over the last 2000 years. Archaeologists must use multiple methods for dating stone features in alpine environments. This Bayesian analysis is a formal effort to combine lichenometry and 14C dating for archaeological interpretation.

Nowadays, most radiocarbon (14C) laboratories can reliably avoid and remove any possible sample contamination during the pretreatment of organic samples (e.g., bones, charcoal, or trees) thanks to a series of methods commonly used by the radiocarbon community. However, what about the final step, the storage of graphite? Rarely do the laboratories produce their graphite and ship it as pressed targets to accelerator mass spectrometry (AMS) facilities for measurement. Pressed graphite in aluminum targets are vulnerable to contamination, and during shipment or storage, exogenous carbon can be introduced again. Here we report a test on various archaeological sample materials from different environments and different periods (from the past three millennia to the Middle Paleolithic period). We transformed them into graphite, pressed the graphite into targets and sent them to two different AMS laboratories to be dated. We observe that packing details of the targets, extended shipment and storage time may lead to contamination which can be avoided by appropriate packaging in tight metal cans and sealed in vacuum bags. Close cooperation and coordination between our chemistry laboratory and the AMS facilities, high standards in contamination removal, and efficient measurement planning enabled us to obtain reliable 14C ages within a short time.

The Falerii Novi Project represents a newly formed archaeological initiative to explore the Roman city of Falerii Novi. The project forms a collaboration of the British School at Rome with a multinational team of partner institutions. Thanks to a rich legacy of geophysical work on both the site and its territory, Falerii Novi presents an exceptional opportunity to advance understanding of urbanism in ancient and medieval Italy. The Falerii Novi Project employs a range of methodologies, integrating continued site-scale survey with new campaigns of stratigraphic excavation, archival research and environmental archaeology. The project aims to present a more expansive and holistic urban history of this key Tiber Valley settlement by focusing on long-run socio-economic processes both within Falerii Novi and as they linked the city to its wider landscape.

The illicit antiquities trade relies on various academic experts for its operations and legitimization. To counter this involvement, academics need to be made aware of how their services might support the trade. A suitable venue for future generations of professionals to obtain this knowledge is their university education. Hence, it is of interest to ask what is taught in university programs in relevant disciplines about the illicit antiquities trade and the forms of academic entanglement within it. This article focuses on course literature in university programs for conservators. It looks at both the official curriculum (explicit and intended teaching) and the hidden curriculum (implicit and unintended teaching) concerning illicit antiquities trade and conservators’ responsibilities vis-à-vis this trade. It finds that the coverage is limited and partly outdated. Further, textbooks might signal that it is acceptable to undertake the treatment of unprovenanced archaeological objects. The study suggests that it is relevant to ask not only if, but also how, the topic of professional responsibility is taught, and it argues that higher education, apart from teaching how to keep clear of activities that promote the trade, should provide the knowledge and skills to actively oppose it.

The small finds discovered during the 1948–1951 excavations by Katherine M. Kenyon and John B. Ward-Perkins at Sabratha were scattered after the 1950s and have taken some time to be re-assembled. The following report on the small objects includes material in silver, copper alloy, iron, lead, glass, semiprecious stones, clay and stone, with a separate report on the substantial bone artefact assemblage. As well as providing the basic data on the objects, some of which are unique to Roman Libya, efforts have been made to put them into their Empire-wide context.

Archaeological research on palaces and architectural spaces related to power factions allow a better understanding of the social dynamics of political economies. Several types of palaces appear in Mesoamerica according to distinct forms of sociopolitical organization. For Tlaxcallan, a Late Postclassic (A.D. 1250/1300–1519) geopolitical state-level polity with a highly collective government, the existence of palaces has been questioned. We reconsider the existence of palaces in Tlaxcallan through the contextual analysis of an architectural complex (CA-2) of Tepeticpac, one of the sectors of the conurbated area. We evaluate the functionality of CA-2 as a palace by examining the processes of occupation and abandonment of the building in relation to its architectural and stratigraphic sequence and the type of associated artifacts. The comparison between archaeological and historical data indicate that Tlaxcallans probably had palaces, but they were less ostentatious compared to others found in societies with more centralized governments.

In much of the Western world, collaborative research undertaken by settler archaeologists readily lends itself, at least in part, to a continuation of the colonial project. Yet, against this backdrop, Australia's First Nations’ peoples continue to work with researchers and to drive systemic change in research practice. Community-engaged archaeology, defined here as codeveloped studies of ancestral places (following Schaepe et al. 2017), is directed to improving relationships between Indigenous peoples and archaeologists. Even so, the practice of archaeology with and for nonsettler communities remains underdeveloped with regard to institutional priorities and funding agency bureaucracies. Here, we (Mirarr Traditional Owners, Mirarr employees, and settler archaeologist researchers) reflect on these issues as part of our ongoing research on the ochres and bim (rock art) of the well-known Madjedbebe rockshelter in the Alligator Rivers region, Northern Territory, Australia.
