This report presents the first in-depth publication of preliminary data from Oued Beht, northwest Morocco, a remarkable site initially identified in the 1930s and now newly investigated. It is based on fieldwork undertaken in 2021–2022 (photogrammetry, survey and excavation), and associated study and analyses. Oued Beht is shown to be a large site of ca. 9–10 hectares in main extent, with many deep pits and convincing evidence for a full package of domesticated crops and animals. Its material culture is abundant and dense, comprising ceramics (including a local painted tradition hitherto barely attested in northwest Africa but comparable to finds in Iberia), numerous polished stone axes, grinding stones and other macrolithics, and a chipped-stone industry. Radiocarbon dates so far cluster at ca. 3400–2900 BC, but there are also indications of earlier and later prehistoric activity. What social activities Oued Beht reflects remains open to interpretation, but it emerges as a phenomenon of strong comparative interest for understanding the wider dynamics of north Africa and the Mediterranean during the fourth and third millennia BC.

This article reports on a new project to investigate the activities of early Homo sapiens in the area of the Chotts ‘megalake’ in southern Tunisia. Excavations in 2015 and 2019 at Oued el Akarit revealed one of a number of Middle Stone Age (MSA) horizons near the top of a long sequence of Upper Pleistocene deposits. The site identified as Oued el Akarit (Sondage 8) consists of lithic artefacts, bone fragments of large ungulates and pieces of ostrich eggshell. Many of the objects are burnt. Excavation of about nine square metres revealed that these were associated with a lightly trampled and combusted occupation surface. Amongst the identified artefacts were Levallois flakes some of which could be refitted, thereby indicating the generally undisturbed nature of the occupation. The lithic finds also included side scrapers and other tools diagnostic of the MSA but significantly no bifacial or tanged tools. OSL (Optically Stimulated Luminescence) dating of the sediments and AMS (Accelerator Mass Spectrometry) radiocarbon dating of ostrich eggshell have produced uncalibrated age determinations in the range 37,000–40,000 years ago, one of the youngest ages for MSA sites in the region. This is the first example of a securely dated later MSA occupation in a riparian environment in south-eastern Tunisia.

The area encompassing the Acacus and Messak mountains in South Western Libya, similarly to the other central Saharan massifs, is characterized by a deeply eroded landscape where Quaternary geo-archaeological archives are rare, especially Pleistocene ones, making it difficult to understand and contextualize past human dynamics within a solid chrono-paleoenvironmental framework. Except for the few caves and open-air contexts where Pleistocene sedimentary sequences are preserved, the vast majority of archaeological evidence from the region is represented by lithic artefacts found on the surface of deflated open-air sites. Nonetheless, artefacts still stand as the main references used to build a rough framework for population dynamics through time. Although the evidence is not as solid as we would like, it allows us to at least reconsider connecting the human presence solely to ‘green’ phases, as a number of population dynamics related to arid landscapes have inferably occurred in the late Middle Pleistocene and in the Late Pleistocene. Coping with changing or difficult ecological settings could have been a driver at different times for behavioral adjustment, large scale displacement, increased interactions between populations and diffusion of technological innovations.

This paper outlines the ways in which the project is addressing the colonial legacy of Henry Wellcome as well as presenting the data from the first three field seasons at Jebel Moya, south-central Sudan. These data have substantially revised our chronological and socio-economic understanding of the site. Our excavations, initiated in 2017 and continued in 2019 and 2022, show a longer, more continuous occupation of the site than has been previously recognised. The faunal and botanical remains have implications for the spread of early domesticates in the eastern Sahel and for climate changes, and raise issues of resilience. There is confirmed human burial activity from at least the third millennium BC onwards, while the pottery continues to yield information about the variety of decoration and, for the final Assemblage 3, data on its usage. Overall, the continued importance of the site for the eastern Sahel is re-emphasised.

The paper reports the preliminary results from the short season of fieldwork that the Cyrenaican Prehistory Project was able to undertake with a small Anglo-Libyan team in September 2013. The work concentrated on continuing the excavation of Trench M down the southern side of the Middle Trench and of Trench D on the southern side of the Deep Sounding below it, the eventual objective being to link these so as to provide a high quality dataset of sedimentary and cultural data from the top to the bottom of the Pleistocene occupation deposit (some 12 m). The ~1 m of sediments investigated in Trench M in the 2013 fieldwork includes carbonate crusts possibly formed in oscillating sub-humid to arid climatic pulses, perhaps likely during Marine Isotope Stage (MIS) 4, around 60,000–70,000 years ago. One of these crusts formed the base on which a hearth-like structure had been built. In Trench D evidence for human occupation appears to decline moving up the profile, coinciding with sedimentary evidence of more frequent disruptive climatic events possibly associated with latter stages of MIS 5.
