The Saharo-Arabian Desert is one of the largest biogeographical barriers on Earth, impeding dispersals between Africa and Eurasia, including movements of past hominins. Recent research suggests that this barrier has been in place since at least 11 million years ago¹. In contrast, fossil evidence from the late Miocene epoch and the Pleistocene epoch...

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...

Recent advances in interdisciplinary archaeological research in Arabia have focused on the evolution and historical development of regional human populations as well as the diverse patterns of cultural change, migration, and adaptations to environmental fluctuations. Obtaining a comprehensive understanding of cultural developments such as the emerg...

Analysis of plant‐wax biomarkers from sedimentary sequences can enable past environmental and hydrological reconstruction and provide insights into past hominin adaptations. However, biomarker preservation in desert contexts has been considered unlikely given the sparse nature of the vegetation within the landscape. Here we evaluate the preservatio...

Archaeological sites with surface hearths are a ubiquitous feature across the arid zones of the Arabian interior. At Jebel Oraf, in the Jubbah basin of the Nefud Desert of northern Arabia, numerous grinding stone fragments were found in association with hearths, though the original purpose of these stones was unclear owing to the poor preservation...

The Neolithic of northern Arabia is characterised by monumental stone structures, ephemeral ‘hearth sites’ indicative of a highly mobile lifestyle, and a rich rock art heritage with iconic representations of domesticated livestock. However, the character and timing of occupation prior to the spread of pastoralism (ca. 6000 BCE) remains elusive, wit...

Among the rock art in Arabia, a little-known Neolithic tradition of large, naturalistic camel depictions stands out. Their geographic distribution and stylistic traits suggest close links with the Camel Site reliefs. Four newly documented panels appear to have been carved by the same individual (or group), tracing repeated movements over hundreds o...

The Camel Site is in the north of Saudi Arabia in the province of al-Jawf. It is characterised by three decaying sandstone hillocks with life-sized 3D engravings (or reliefs) of camels and equids likely carved during later prehistory. A survey in the central area of the site identified clusters of flakes and other flintknapping remains in the lower...

Archaeologists have long emphasized the importance of large-scale excavations and multi-year or even decades-long projects at a single site or site complex. Here, we highlight archaeological field strategies, termed coring, profiling, and trenching (CPT), that rely on relatively small-scale excavations or the collection of new samples from intact d...

Pleistocene hominin dispersals out of, and back into, Africa necessarily involved traversing the diverse and often challenging environments of Southwest Asia 1–4 . Archaeological and palaeontological records from the Levantine woodland zone document major biological and cultural shifts, such as alternating occupations by Homo sapiens and Neandertha...

The life-sized, naturalistic reliefs at the Camel Site in northern Arabia have been severely damaged by erosion. This, coupled with substantial destruction of the surrounding archaeological landscape, has made a chronological assessment of the site difficult. To overcome these problems, we combined results from a wide range of methods, including an...

Studies of modern carnivore accumulations of bone (i.e., neo-taphonomy) are crucial for interpreting fossil accumulations in the archaeological and paleontological records. Yet, studies in arid regions have been limited in both number and detailed taphonomic data, prohibiting our understanding of carnivore bone-accumulating and -modifying behavior...

Hearth sites are characteristic of Holocene occupation in the Arabian sand seas but remain mostly unstudied. Excavations of two multi-period hearth sites in the Jebel Oraf palaeolake basin, in the oasis of Jubbah, now substantially increase our knowledge of these sites. In total, 17 of 170 identified hearths were excavated at Jebel Oraf 2 (ORF2), a...

The Arabian Peninsula is a critical geographic landmass situated between Africa and the rest of Eurasia. Climatic shifts across the Pleistocene periodically produced wetter conditions in Arabia, dramatically altering the spatial distribution of hominins both within and between continents. This is particularly true of Acheulean hominins, who appear...

We investigated the rock art (petroglyphs) in the Al‐Quwaiyah Governorate (Saudi Arabia) with focus on the Musayqira site. Iconographic analysis showed a broad variety of human depictions, game animals (ibex, ass, ostrich, lion, etc.), domestic animals (cattle, camel, horse, dog, etc.), inscriptions and abstract symbols. Archaeometric measurements...

The nature of human dispersals out of Africa has remained elusive because of the poor resolution of paleoecological data in direct association with remains of the earliest non-African people. Here, we report hominin and non-hominin mammalian tracks from an ancient lake deposit in the Arabian Peninsula, dated within the last interglacial. The findin...

Between 10 and six thousand years ago the Arabian Peninsula saw the most recent of the ‘Green Arabia’ periods, when increased rainfall transformed this generally arid region. The transition to the Neolithic in Arabia occurred during this period of climatic amelioration. Various forms of stone structures are abundant in northern Arabia, and it has b...

Archaeological surveys and excavations in the Jebel Oraf palaeolake basin, north-western Saudi Arabia, have identified a well-preserved early- to mid-Holocene landscape. Two types of occupation site can be distinguished: nine small and ephemeral scatters from single occupation phases on the slopes of sand dunes and three hearth sites indicative of...

Over the past decade, a growing interest has developed on the archaeology, palaeontology, and palaeoenvironments of the Arabian Peninsula. It is now clear that hominins repeatedly dispersed into Arabia, notably during pluvial interglacial periods when much of the peninsula was characterised by a semiarid grassland environment. During the intervenin...

In recent years, the Arabian Peninsula has emerged as a key region for elucidating hominin and faunal evolution and dispersals between Africa and Eurasia. Central to this research is the middle Pleistocene site of Ti's al Ghadah (TAG) which has yielded a diverse and abundant fossil faunal assemblage and the earliest chronometrically dated evidence...

The land bridge formed by the Sinai Peninsula is one of the major routes proposed for hominin dispersal out of Africa for both Homo erectus and H. sapiens populations, and its neighbouring regions are, therefore, key to understanding these dispersals. Directly adjacent to the land bridge, the Saudi Arabian northern Red Sea and Gulf of Aqaba coastli...

Surface artifacts dominate the archaeological record of arid landscapes, particularly the Saharo‐Arabian belt, a pivotal region in dispersals out of Africa. Discarded by hominins, these artifacts are key to understanding past landscape use and dispersals, yet behavioral interpretation of present‐day artifact distributions cannot be carried out with...

This chapter examines the different sources of evidence—phylogenetic, palaeoclimatic and archaeological—that have been used to investigate the hypothesis that early human dispersals from Africa during the late Pleistocene were facilitated by exploitation of marine resources and seafaring abilities and followed a predominantly coastal route includin...

Despite its largely hyper-arid and inhospitable climate today, the Arabian Peninsula is emerging as an important area for investigating Pleistocene hominin dispersals. Recently, a member of our own species was found in northern Arabia dating to ca. 90 ka, while stone tools and fossil finds have hinted at an earlier, middle Pleistocene, hominin pres...

Abstract The Acheulean is the longest lasting cultural–technological tradition in human evolutionary history. However, considerable gaps remain in understanding the chronology and geographical distribution of Acheulean hominins. We present the first chronometrically dated Acheulean site from the Arabian Peninsula, a vast and poorly known region tha...

The origins of agriculture in South-west Asia is a topic of continued archaeological debate. Of particular interest is how agricultural populations and practices spread inter-regionally. Was the Arabian Neolithic, for example, spread through the movement of pastoral groups, or did ideas perhaps develop independently? Here, the authors report on rec...

Records of former lake and wetland development in present day arid/hyper-arid environments provide an important source of information for palaeoclimatic and palaeoenvironmental studies. In Arabia, such records are typically confined to eccentricity-modulated insolation maxima, and are often spatially and temporally discontinuous. Here we present re...

Despite occupying a central geographic position, investigations of hominin populations in the Arabian Peninsula during the Lower Palaeolithic period are rare. The colonization of Eurasia below 55 degrees latitude indicates the success of the genus Homo in the Early and Middle Pleistocene, but the extent to which these hominins were capable of innov...

Understanding the timing and character of the expansion of Homo sapiens out of Africa is critical for inferring the colonization and admixture processes that underpin global population history. It has been argued that dispersal out of Africa had an early phase, particularly ~130–90 thousand years ago (ka), that reached only the East Mediterranean L...

Since 2012, a new phase of landscape survey for archaeological remains from the Palaeolithic has been undertaken in the provinces of Jizan and Asir in Southwestern Saudi Arabia. This is the first Palaeolithic landscape survey in this area since the Comprehensive Survey of the Kingdom undertaken between 1977 and 1982. More than 100 Palaeolithic site...

Aim Our knowledge of the prehistoric distribution of animal species is so far largely dependent on the location of excavated archaeological and palaeontological sites. In the absence of excavated faunal remains, many species that were present in the Levant and North Africa have been assumed to have been absent on the Arabian Peninsula. Here, we exp...

Open Access Accepted Manuscript available at: http://eprints.whiterose.ac.uk/113622/ The role played by the Arabian Peninsula in hominin dispersals out of Africa has long been debated. The DISPERSE Project has focused on south-western Arabia as a possible centre of hominin settlement and a primary stepping-stone for such dispersals. This work has...

A systematic survey of rock art and associated archaeological features in the Jubbah oasis provides evidence of Holocene occupation from the early Holocene to the present. In total 1249 panels with rock art and inscriptions, and 159 archaeological sites, were recorded on twelve different jebels. Analyses of rock art content and engraving stratigrap...

We report on a preliminary exploration of the submerged landscapes in the Saudi Arabian sector of the southern Red Sea aboard the Hellenic Centre for Marine Research (HCMR) Research Vessel, AEGAEO, in May–June 2013. The survey sampled areas of the continental shelf down to the shelf margin at ~130 m depth in the vicinity of the Farasan Islands and...

Mid-latitude dune fields offer significant records of human occupations in southwest Asia, reflecting human responses to past climate changes. Currently arid, but episodically wetter in the past, the Nefud desert of northern Saudi Arabia provides numerous examples of human-environment interactions and population movements in the desert belt. Here w...

Several hundred Middle Palaeolithic (MP) archaeological sites have now been identified in the Arabian Peninsula. However, the study of lithic raw material properties and related procurement behaviours is still in its infancy. Here we describe raw material procurement and early stage lithic reduction at MP sites in the Jubbah palaeolake basin, in th...

The animal species depicted in the rock art of Shuwaymis, Saudi Arabia, provide a record of Holocene climatic changes, as seen by the engravers. Of 1903 animal engravings, 1514 contained sufficient detail to allow identification with confidence. In addition, the stratigraphy of the engravings and the depiction of domesticates provide a broad chrono...

The Pleistocene archaeological record of the Arabian Peninsula is increasingly recognized as being of great importance for resolving some of the major debates in hominin evolutionary studies. Though there has been an acceleration in the rate of fieldwork and discovery of archaeological sites in recent years, little is known about hominin occupation...

The Middle Palaeolithic record of the Arabian Peninsula can provide crucial evidence for understanding human dispersal. The authors summarise the archaeological evidence and suggest some of the routes taken by the earliest humans coming out of Africa, including one implying the use of boats. Early populations adapted to a hospitable environment, bu...

The exploitation of coastal landscapes and resources in human prehistory has long been a subject of debate, particularly in assessing the conditions and timing of global dispersals of modern humans from Africa. Coastal landscapes potentially provide highly attractive concentrations of different marine and terrestrial resources, seen in Holocene she...

A joint archaeological and geoscientific exploration of the continental shelf of Farasan Islands, Saudi Arabia, South Red Sea, was conducted in May–June 2013 aboard HCMR's Research Vessel AEGAEO with the aim of exploring systematically the submerged landscapes. The region is regarded as one of the primary pathways of dispersal for early human popul...

The purpose of the preliminary field season at Al-Magar was to map the archaeological site in order to provide baseline information that could help prepare the SCTH for future field investigations. Another aim was to provide an interdisciplinary expertise regarding the potential importance of the Al-Magar site, placing it in environmental and cultu...

Coastal landscapes potentially provide highly attractive concentrations of different marine and terrestrial resources but are not uniformly attractive...

The role of coastal regions and coastlines in the dispersal of human populations from Africa and across the globe has been highlighted by the recent polarisation between coastal and interior models. The debate has been clouded by the use of the single term ‘coastal dispersal’ to embrace what is in fact a wide spectrum of possibilities, ranging from...

The interpretation of Acheulean landscape use through the analysis of artefact distributions over a range of environmental settings is vital for understanding early hominin behaviour. Such approaches have been successfully applied in areas such as East Africa and South Africa, where long-term and sustained archaeological research has led to the dev...

Freshwater availability is critical for human survival, and in the Saharo-Arabian desert belt repeated fluctuations between aridity and humidity over the Quaternary mean the distribution of freshwater was likely a primary control upon routes and opportunities for hominin dispersals.

Recent archaeological discoveries indicate that the Arabian Peninsula played an important role in Late Pleistocene hominin dispersals. The presence of Middle Palaeolithic archaeological sites in the Nefud Desert of northern Saudi Arabia demonstrates that hominins moved far inland, probably following networks of ancient lakes and rivers deep into th...

The Nefud Desert is crucial for resolving debates concerning hominin demography and behaviour in the Saharo-Arabian belt. Situated at the interface between the Mediterranean Westerlies and African Monsoonal climate systems, the Nefud lies at the centre of the arid zone crossed by Homo sapiens dispersing into Eurasia and the edges of the southernmos...

Between the Levant and the Indian sub-continent only a few Acheulean sites have been documented, hampering models of hominin dispersals. Here we describe the first Acheulean sites to be discovered in the Nefud Desert of northern Arabia. The four sites occur in a variety of settings including adjacent to an alluvial fan drainage system, at a knappab...

Many parts of the Arabian Peninsula contain rock art that has received minimal archaeological attention or has not yet been thoroughly surveyed. In 2001 an extensive rock-art complex called Shuwaymis, Ha'il Province, Saudi Arabia was brought to the attention of the Saudi General Commission for Tourism and Antiquities. This paper sets out the result...

Southwestern Saudi Arabia occupies a key location on the Southern Route out of Africa, yet little is known about the Palaeolithic occupation of the region. The DISPERSE project is undertaking survey in Jizan and Asir regions, and has so far identified over 50 new locations with Early and Middle Stone Age artefacts. These locations are situated in a...

Over 3,000 shell-midden sites have been located in the southern Red Sea using digital-imaging techniques, in a combination of palaeo-landscape reconstruction and remote survey. The primary methods include digital-imaging techniques – high-resolution satellite images, false colour images and radar data. Surveying and recording these sites during exc...

The archaeology of the Arabian Peninsula is pivotal to understanding the timing and mode of dispersals of hominin populations from Africa, with growing evidence supporting a ‘Southern Route’ across the Hanish Sill in the southern Red Sea. Yet despite recent key discoveries, our understanding of the hominin occupation of the Peninsula remains patchy...

Reconstructing the landscapes inhabited by Palaeolithic populations presents a number of challenges. Primarily, differential preservation and exposure of sites at both landscape and local scales biases the observed archaeological record. Only by developing robust models of landscape evolution can the taphonomic constraints of the record be fully as...

The authors have undertaken a systematic survey of rock art along the Jubbah palaeolake in northern Saudi Arabia and interpret the results using GIS. They conclude that the overwhelming majority of prehistoric rock art sites overlook contemporary early Holocene palaeolakes, and that the distribution of later Thamudic rock art offers insights into h...
