Landscape positioning of Neolithic mustatil stone structures along the margins of the Nefud Desert, Saudi Arabia

Monumental rectangular stone structures called mustatils are an important emerging feature of the Holocene archaeological record of northwestern Arabia. To date, few have been excavated, with available radiocarbon dates suggesting an age range of ca. 5400–4200 BC. Here we present a rigorous spatial analysis to identify the patterning and landscape context of 169 mustatils in the southern and western margins of the Nefud Desert. This included: (1) a systematic survey of satellite imagery to identify mustatils; (2) viewshed analysis to examine location and landscape visibility; (3) a point process model to understand how diverse environmental and landscape variables affect mustatil locations; (4) mark correlation function to assess spatial patterning of mustatils based on their size. Results indicate that mustatil locations are determined most by proximity to water (likely locations of enhanced surface water occurrence under the enhanced humidity of the Mid-Holocene), on east facing slopes, close to rocky areas, at elevations between 880 and 950 masl, and on or near topographic ridges (positive topographic position index). Viewshed analysis showed that mustatils are preferentially located in areas that have good views, but not the best that are available, indicating complex landscape positioning that balances a range of topographic and behavioural factors. Using a rank permutation method with size (length) of mustatils as a proxy for labour mobilization we show that mustatils within clusters are not arranged hierarchically based on size, and were likely built by non-stratified groups of people. Our analyses show that people were choosing multiple factors when deciding where to build mustatils, and that the distribution of mustatils may relate to different groups of people resulting in the construction of complex ritual landscapes. As one of the earliest examples of large-scale monumental stone structure construction in global prehistory, understanding mustatils can enlighten us on human-environment interaction during the Neolithic.

Carnelian Beads from the Early Bronze Age Fifa Cemetery, Jordan: Aspects of Technology, Use, and Exchange

Between 1989 and 1990 the Expedition to the Dead Sea Plain excavated a group of 15 tombs at the Early Bronze Age IA (c.3700–3400) cist-tomb cemetery at Fifa, Jordan. These tombs contained a variety of grave goods including beads made from carnelian. The present study employs morphometric data and microscopic indicators of manufacture and use to explore the relationship between carnelian beads, burial practices, manufacturing processes, and exchange. Manufacturing traces suggest that the beads from Fifa were created through a process of knapping and progressive stages of abrasion. Beads were perforated through pecking on one or two sides. Polish from use was observed on beads throughout the assemblage, suggesting that the beads were worn prior to their deposition, albeit for an unknown period of time. The amount of this use polish was highly variable suggesting that different beads were in use for greater or lesser periods of time. Morphometric and manufacturing data were utilized in tandem in order to suggest where the beads were produced. While a great deal of prior scholarship has suggested that carnelian beads found in the Early Bronze Age Levant originated in Egypt, we argue that some or all of these beads may alternatively have been produced in Northwestern Arabia or Eastern Jordan. This study demonstrates the value of systematic approaches to the study of beads in order to better understand processes of ritual behavior, craft production, and exchange.

Intra-Turonian stratigraphic reorganization on the Arabian Plate

Shallow-marine carbonate deposition was widespread across the Arabian Plate during much of the Late Permian–Mesozoic but was significantly interrupted by a major tectonically driven stratigraphic reorganization that took place within the Turonian. Published literature terms this the ‘Wasia–Aruma Break’, the ‘mid-Turonian Unconformity’, or the ‘K150 Sequence Boundary (SB)’. It is widely understood that this event relates to subduction in a closing Neotethys Ocean and obduction onto the continental margin, especially in the southeastern part of the plate. As well as a change in facies, a hiatus of variable duration is present, associated with erosion of the underlying stratigraphy. Despite the event being known for several decades, precision on its timing has been lacking due to the limitations of biostratigraphic data and because few other chronostratigraphic proxies have been employed. In order to rectify this, all relevant biostratigraphic data from across the Arabian Plate have been synthesized and evaluated in the context of a review of chronostratigraphic calibration of standard biozones from multiple fossil groups. This shows that the youngest preserved rocks beneath the K150 SB can be assigned to the middle Turonian Helvetoglobotruncana helvetica planktonic foraminifera zone or Collignoniceras woollgari ammonite zone. The oldest rocks above the K150 SB can be assigned to the same biozones, supporting the assertions that it is a very short duration event. Whilst obduction may have initiated earlier (as supported by the recognition of precursor events), crustal loading was sufficient by 91.5 Ma to develop a forebulge in the eastern part of the plate with associated uplift and erosion. A review of relative sea-level change during the Turonian has been carried out to investigate eustatic signals during this time. In multiple sections around the world, a sea-level fall in the upper part of the woollgari Zone of European usage can be detected. This appears to coincide with an episode of climate cooling. However, despite there being correspondence between the K150 SB and a significant eustatic event, this seems mostly coincidental as the tectonic drivers at this time across Arabia were much more dramatic. This is especially true in southeastern Arabia. In northwestern Arabia, tectonic quiescence may have allowed eustasy to dominate. In any case, a eustatic fall would have amplified the effects of tectonics across the entire region.

The ramparts of Khaybar. Multiproxy investigation for reconstructing a Bronze Age walled oasis in Northwest Arabia

The multidisciplinary investigation carried out between 2020 and 2023 by the Khaybar Longue Durée Archaeological Project (CNRS-RCU-AFALULA) demonstrates that the Khaybar Oasis was entirely enclosed by a rampart in pre-Islamic times, like several other large regional walled oases in north-western Arabia (Tayma, Qurayyah, Hait, etc.). The cross-referencing of survey and remote sensing data, architectural examinations and the dating of stratified contexts have revealed a rampart initially some 14.5 km long, generally between 1.70 m and 2.40 m thick, reinforced by 180 bastions. Preserved today over just under half of the original route (41 %, 5.9 km and 74 bastions), this rampart dates back to the Bronze Age, between 2250 and 1950 BCE, and had never been detected before due to the profound reworking of the local desert landscape over time. This crucial discovery confirms the rise of a walled oasis complex in northern Arabia during the Bronze Age, a trend that proved to be central to the creation of indigenous social and political complexity.

Jethro and Moses in Dialogue (Exodus 18: 8–26): Ethics of Communitarian Responsibility

Jethro’s dialogue with his son-in-law, Moses, in the Book of Exodus 18: 8–26 can be summarised according to the four-fold elements of subsidiarity, communitarian responsibility, delegation, and synodality, which lead to focus in life. The Elder priest of Midian, in north-western Arabia, advises his son-in-law to practise subsidiarity and communitarian ethical responsibility by undertaking the fundamental task of teaching the precepts, statutes, and instructions that would form the backbone of the twelve-tribe nation of Israel. Subsidiarity and delegation were to be exercised by different levels of leadership, together with Moses himself, in the choice of the exemplary leaders who would both teach Israel and judge minor issues among its people. Finally, synodality is advised by Jethro so that the People of Israel and their leaders can reach their ultimate aim in the Promised Land in peace. Subsidiarity, communitarian responsibility, delegation and synodality would bring Israel as a nation gathered around their one God, YHWH, according to the aim for which they were called from slavery in Egypt to freedom in Canaan.

Dadan and Lihyan, a Kingdom or Two Kingdoms: A Critical Study through Archaeological Evidence

The kingdoms of Dadan and Lihyan are among the most prominent ancient Arab kingdoms that arose in northwestern Arabia during the first millennium BC, specifically in al-‘Ula, considered to the capital of these two kingdoms. Interest in those kingdoms has increased significantly since the beginning of this millennium, when fieldwork started in al-‘Ula, specifically in sites such as Dadan, Umm Daraj, Tell Al-Kuthib and others. Despite this increase in interest, two prominent issues about the relationship between Dadan and Lihyan are the confusion regarding whether they were two separate kingdoms or one kingdom with different names, and the origin of the Dadanites and Lihyanites. This article examines these issues through the analysis of the available archaeological evidence.

Supervolcanic resurfacing in northwestern Arabia Terra, Mars

An area roughly 9 × 105 km2 within northwest Arabia Terra contains several depressions interpreted to be supervolcanic calderas, contained within a chemical province considered consistent with large-scale igneous processes. Despite the underlying global significance to climate and geology, the supervolcanic hypothesis is yet to be tested with comprehensive compositional or geophysical analyses. Here we present geochemical evidence consistent with regional-scale supervolcanic resurfacing, with associated eruptions capable of degassing a climate-altering ∼108 kg of sulfur phases. Through gravitational modeling, we find evidence of low-density pyroclastic loading within this region, and a low elastic thickness, suggestive of a higher heat flow during the eruptive process. Our geochemical observations within this region reinforce its compositional uniqueness compared to contemporaneous volcanoes.

Can a Local Descent Group Become an International Network? Research on the Rashāyidah in Five Countries

Local descent groups that all have the name – Rashāyidah – are found in many places in the eastern Arab world. There is evidence that at least some of these groups originated in northwest-ern Arabia, where some of their ancestors lived centuries ago. More significantly, many of them have recently become aware of each other’s existence. Some are constructing a historical and genealogical narrative about common out-migration from Arabia. This narrative does more than explain why they share the same name; it also (re)constructs the kinship bonds that link them. Research has begun in Jordan, Kuwait, Palestine, Saudi Arabia, and Sudan to explore this process of “awakening” to a common past. Nine researchers are collecting ethnographic and linguistic data about six different Rashāyidah groups and the various localities where they live. The researchers will describe the relationships of each group with its neighbors and will explore the motivations for adopting a new, diasporic, identity while at the same time re-working the de-tails of their established tribal and national identities.

Yield Estimation and Event Discrimination of the 4 August 2020 Beirut Chemical Explosion

AbstractWe investigate the 4 August 2020 Beirut accidental chemical explosion based on regional seismic data recorded at both on- and off-shore stations. The Lg-wave body-wave magnitude is mb(Lg)=3.30±0.46 for the Beirut explosion. The explosive yield obtained using an empirical magnitude-yield relation based on a fully buried explosion source model is only 0.112 kt. Alternatively, the yield estimated using an empirical relation between the yield and crater size is 1.22 kt, with the uncertainties between 0.48 and 2.3 kt. The latter is closer to reality. The P/S spectral amplitude ratios, including Pg/Lg, Pn/Lg, and Pn/Sn, are calculated for the Beirut explosion and nearby natural earthquakes. We find the P/S spectral ratios are effective in discriminating the explosion from earthquakes in the Northwestern Arabia plate. By comparing the spectral ratios of large open-pit explosions, including the Beirut, Xiangshui, and Tianjin explosions, with those from historical nuclear explosions, buried small chemical explosions, and natural earthquakes, we further investigate the detailed differences of network-averaged P/S spectral ratios between different source types.

New Arabian desert kites and potential proto-kites extend the global distribution of hunting mega-traps

New desert kites have been discovered over the past two years during the observation of satellite images of north-western Arabia. Great numbers of these large archaeological traps were known prior to this from the Aralo-Caspian zone to the Arabian Peninsula. Many of these recent discoveries are constructions without the same closed enclosures as kites, but which are nonetheless clearly related to kites as, like them, they comprise pit-traps. The study of all these ‘open kites’, based on the observation of satellite images, focused on the characterisation of their morphology, topographical location and comparisons of their geographical distribution with that of kites in the region. The analysis of these data was confirmed by a field study in Khaybar, Saudi Arabia, of a sample of open kites in the spring of 2021, during which elements of relative chronology were observed. Open kites are more rudimentary and less systematically organised than kites and represent a ‘mega-trap’ form that pre-dates the desert kites. Groups of kites were identified on the basis of morphological resemblances, using two different methods, resulting in the overall mapping of mega-traps in the southern part of the kite distribution range. These localised morphological variations probably reflect the evolution of the hunting technique using these traps. They provide new information, which, combined with chronological data from excavations, aims to record the spread of the kite phenomenon.

The mustatils: cult and monumentality in Neolithic north-western Arabia

North-western Arabia is marked by thousands of prehistoric stone structures. Of these, the monumental, rectilinear type known as mustatils has received only limited attention. Recent fieldwork in AlUla and Khaybar Counties, Saudi Arabia, demonstrates that these monuments are architecturally more complex than previously supposed, featuring chambers, entranceways and orthostats. These structures can now be interpreted as ritual installations dating back to the late sixth millennium BC, with recent excavations revealing the earliest evidence for a cattle cult in the Arabian Peninsula. As such, mustatils are amongst the earliest stone monuments in Arabia and globally one of the oldest monumental building traditions yet identified.

A Metallurgical Perspective on the Birth of Ancient Israel

The re-emergence of the copper industry in the Arabah valley between the twelfth and ninth centuries BCE stimulated wealth and economic development across the whole Southern Levant. Combining this reality with the metallurgical background of ancient Yahwism provides a material basis for the spread, from the early Iron Age, of the worship of YHWH in ancient Israel and neighboring nations, especially Edom. These findings strengthen the Qenite hypothesis of the origin of the Israelite religion. They also suggest that an official cult of YHWH, replacing a traditional esoteric dimension, is the main novelty of the Israelite religion. The claim of YHWH’s intervention in history, apparently absent from traditional Yahwism, is the other theological novelty advanced by the Israelites. This article suggests that both innovations are rooted in a desert-shaped form of Yahwism especially adapted to the way of life and the environment of Northwestern Arabia, the land of Biblical Midian.

Monumentality, Social Memory, and Territoriality in Neolithic–Chalcolithic Northwestern Arabia

ABSTRACT Recent excavations undertaken by the Aerial Archaeology in the Kingdom of Saudi Arabia (AAKSA) project have recovered significant skeletal material, evidence for funerary offerings, including jewelry, and the earliest chronometrically dated domestic dog in the Arabian Peninsula. Despite being heavily disturbed by recent looting, these monumental funerary structures were found to be collective burials dating to the 5th and 4th millennia b.c. The evidence recovered from these graves provides new insight into the social and funerary landscapes of northwestern Arabia during the Neolithic and Chalcolithic periods, shedding light upon issues of social memory, territoriality, and monumentality in the Middle Holocene of the Arabian Peninsula.

Madian revealed? Assessing the history and archaeology of the oasis of al-Badʿ in northwestern Arabia

The location of Madian (or Midian), a toponym or ethnonym mentioned many times in the Old Testament and the Qurʾān, has been the subject of intense scientific debate since the 19th century. In this article, we provide an overview of textual sources and field data leading many researchers to identify Madian with the oasis of al-Badʿ in Northwest Arabia. The extent and variety of remains on this archaeological site-explored for the first time by a Franco-Saudi mission (2017-2021)-confirm a long and rich history that remained forgotten until today. The reassessment of scientific arguments tends to show, without much doubt, that the oasis of al-Badʿ was indeed Madyan in Islamic times, and most likely Madiama at the turn of the first millennium ce. The oasis was likely part of a large Midianite tribal confederation in the first millennium bce and possibly even earlier, at the end of the second millennium bce. The oldest traces of the occupation of the oasis date back to the seventh millennium bce.

The Lomonosov Crater Impact Event: A Possible Mega‐Tsunami Source on Mars

AbstractRecent research suggests that major meteorite impact events into a Late Hesperian/Early Amazonian ocean likely produced a mega‐tsunami that would have resurfaced coastal areas in northwestern Arabia Terra. The orientations of the associated lobate deposits, a conspicuous type of landforms called Thumbprint Terrain, suggests that if an impact event triggered the mega‐tsunami, the most likely location of the source crater is within the northern plains regions situated north of Arabia Terra. This study focuses on the identification of impact craters that impacted into the ocean and are likely to have produced the tsunami. We selected 10 complex impact craters, based on their diameters, location, and geomorphic characteristics. Of those, the Late Hesperian ~120‐km‐diameter Lomonosov crater exhibits a unique topographic plan view asymmetry (compared to other similar‐sized and similar‐aged craters in the northern plains such as Micoud, Korolev, and Milankovic). We attribute its broad and shallow rim, in part, to an impact into a shallow ocean as well as its subsequent erosion from the collapsing transient water cavity. The likely marine formation of the Lomonosov crater, and the apparent agreement in its age with that of the Thumbprint Terrain unit (~3 Ga), strongly suggests that it was the source crater of the tsunami. These results have implications for the stability of a late northern ocean on Mars.

Tethys ocean withdrawal and continental peneplanation—An example from the Galilee, northwestern Arabia

During the early Oligocene northeast Africa (Ethiopia, Sudan, Egypt) and Arabia (Yemen, Saudi Arabia, Jordan, Sinai and southern Israel) progressively emerged from marine conditions. Their complete subaerial exposure was accompanied by widespread erosion. Its products were transported across northeast Gondwana to the nearby Mediterranean and Mesopotamian basins while leaving behind a Regional Truncation Surface (RTS). The uplift mechanism is debated. Some claim it results from the Oligocene updoming of Afar mantle plume across northeastern Gondwana. Others suggest GondwanaEurasia convergence that reached hard-docking during the Oligocene is the dominant process. Miocene-to-Holocene post-truncation tectonics deformed the leveled RTS (peneplain) relief while erosion continued. As a result, only scarce and widely distributed evidence for erosion remained across Arabia. The current study addresses this debate through the examination of the morphological development of the converging plate on the verge of entering the subduction zone. The study focuses on the mode of erosion across the Galilee basins of northern Israel. Based on the interpretation of 69 multichannel seismic reflection profiles (extending along 800 km), correlated with 68 boreholes and all previous geological mapping, we distinguish between pre-, syn- and post-truncation stratigraphic units. Results show that the RTS subcrop comprises a mosaic of diachronous formations, spanning the Upper Cretaceous and Oligocene. Stratigraphy constrains the overall duration of truncation between Late Eocene and Early Miocene. A new observation into the truncation period shown here enhances the morphological expression of ocean bottom exposure. The maximum thickness of strata removed reaches ˜1300 m during a 7 ± 2 million year time window. A conservative time estimation yields a weathering rate of 0.186 ± 0.058 mm per year, under a subtropical climate suggested for the Oligocene in this region. Preservation of syn-truncation sediments in local fault-bounded depressions attests to a regional NNE trending flexural uplift accompanied by local extensions. Truncation sediments derived from these erosional events accumulated across the western and eastern flanks of the Galilee, under marine conditions. We suggest that this flexure developed along a northward propagating arm of the Afar plume. This case study may serve as an example for the morphological development of a tectonic plate before its entrance into a subduction zone.

Rock varnish on petroglyphs from the Hima region, southwestern Saudi Arabia: Chemical composition, growth rates, and tentative ages

We investigated rock varnish formed on sandstone and petroglyphs in the Hima area, southwestern Saudi Arabia. To characterize the rock varnish, we made in-situ measurements by portable x-ray fluorescence (pXRF) and analyzed samples by femtosecond laser-ablation inductively coupled–plasma mass spectrometry (fs LA-ICP-MS). Detailed chemical analysis of the rock varnish samples and adjacent soil or aeolian dust yielded information about the varnish’s geochemical context and formation mechanism. Untypically low positive Ce anomalies in the rock varnish samples correlated with negative Ce anomalies in the dust, supporting the hypothesis that the dust is the source of the varnish material. To study the varnish development, we made use of the fact that engraving the petroglyphs exposes a fresh bare sandstone surface without varnish, on which varnish regrows subsequently. We determined by pXRF the areal density of manganese (Mn) and iron (Fe) that had been deposited as rock varnish since the creation of the rock art. The rates of Mn deposition in the newly formed varnish were then estimated by correlating the areal density of Mn in Ancient Arabian and Old Arabic inscriptions with their known age ranges. The observed deposition rates showed substantial variability resulting from differences in exposure conditions of the rock surface, but were in a range comparable with that of our previous measurements in northwestern Arabia. This variability could be reduced significantly by referencing the measurements to the intact varnish adjacent to the individual petroglyphs. This normalization provided a much clearer relationship between varnish deposition and age, and enabled tentative ages to be assigned to rock art motifs without previously known ages. These tentative ages spanned most of the Holocene period and were consistent with the culturally or ecologically derived ages of the animal and human figures depicted in the rock art and the styles of scripts used in different periods.

Living at the wadi – integrating geomorphology and archaeology at the oasis of Qurayyah (NW Arabia)

ABSTRACT The archaeological site Qurayyah, situated in the NW of the Tabuk Province of Saudi Arabia, has been repeatedly described as one of the largest and most significant oases of Northwestern Arabia. Human occupation in the oasis started at least from the early Holocene and continued to the Nabatean, Roman and late Byzantine period. The hydrologically favored position results from its specific geomorphological location where the plateaus fade towards the east and the landscape opens towards the Tabuk Basin so that a balanced water supply was ensured. We present a geomorphological map (1:20,000; main map) based on the interpretation of a high-resolution satellite image and detailed control in the field. The map integrates archaeological, hydraulic and natural features in order to show how the people at Qurayyah structured their landscape and developed water management strategies in relation to prevailing geomorphological processes during the incipient phase (Bronze Age) of the oasis.
