International audience; In southern and south-eastern Arabia, the Neolithic developed between 6500 and 3100 BCE. In the Sultanate of Oman, occupation occurred along wadi banks, around paleolakes, and at large shell-middens accumulated on the shores of the Arabian Sea. Nevertheless, the origins and development of human occupation on the Arabian Sea islands are poorly known, if not totally undocumented. After exploring the archaeological potential of the large island of Masirah, we focused our research on the small Al-Hallaniyat archipelago (formerly known as the Kuria Muria islands). A preliminary archaeological survey led us to test several sites belonging to different occupational phases on the island, and we explored the largest shell-midden at the HLY-4 site in 2014 and 2019. Radiocarbon dating results, along with lithic analysis, demonstrate that at around 4200-4000 BCE, a Neolithic community settled the largest island (Al-Hallaniyah). While goats and dogs had been introduced as livestock, fish and dolphins were regularly fished and captured as a main food resource together with marine turtles and nesting birds. At HLY-4, not only lithic and bone artifacts characterize the assemblage, as standardized discoid marine-shell beads were also manufactured. The Neolithic conquest of Masirah Island occurred early in the Neolithic (at the beginning of the sixth millennium BCE), while the settlements on the Farasan islands (in the Red Sea) are dated to around 4500 BCE, and thus the ones on the Al-Hallaniyat archipelago to the end of the fifth millennium BCE. In Arabia, their chronological assessment marks the final conquest of the insular areas.

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 areas between the sandstone spurs and larger silcrete tools directly underneath the animal depictions. Some of these tools presented abraded edges, possibly from prolonged contact with the soft and abrasive sandstone that constitutes the rock spurs where the animals were carved. Experiments were performed to test this hypothesis and have a reference collection for further traceological analysis. The chaine opératoire of the experimental engraving tools, from raw material procurement, tool manufacture and use, reuse and discard, was conducted with locally available materials comparable to the archaeological specimens. Specific experimental variables, including how the force was applied, in what direction the movement took place and the orientation of the stone tool during the experiment, were also recorded. Macro- and microscopic analyses of the experimental collection and a sample of archaeological artefacts seem to show that the ancient tools found on the surface were probably used to make the camelid and equid reliefs at the site., Open Access funding enabled and organized by Projekt DEAL.

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 analysis of surviving tool marks, assessment of weathering and erosion patterns, portable X-ray fluorescence spectrometry, and luminescence dating of fallen fragments. In addition, test excavations identified a homogenous lithic assemblage and faunal remains that were sampled for radiocarbon dating. Our results show that the reliefs were carved with stone tools and that the creation of the reliefs, as well as the main period of activity at the site, date to the Neolithic. Neolithic arrowheads and radiocarbon dates attest occupation between 5200 and 5600 BCE. This is consistent with measurements of the areal density of manganese and iron in the rock varnish. The site was likely in use over a longer period and reliefs were re-worked when erosion began to obscure detailed features. By 1000 BCE, erosion was advanced enough to cause first panels to fall, in a process that continues until today. The Camel Site is likely home to the oldest surviving large-scale (naturalistic) animal reliefs in the world., We wish to thank HRH Prince Badr b. Abdullah b. Mohammed b.

International audience; For almost a century there has been debate on the functional interpretation of desert kites. These archaeological structures have been interpreted as constructions for animal hunting or domestication purposes, sometimes for both, but with little conclusive evidence. Here, we present new evidence from a large-scale research programme. This unprecedented programme of archaeological excavations and geomatics explorations shows the unequivocal and probably exclusive function of kites as hunting traps. Considering their gigantic size, as well as the significant energy and organization required to build them, these types of traps are called mega-traps. Our research is based on five different field studies in Armenia, Jordan, Kazakhstan and Saudi Arabia, as well as on satellite imagery interpretation across the global distribution area of kites throughout the Middle East, the Caucasus and Central Asia. This hunting interpretation raises questions about the transformation of the landscape by human groups and the consequent anthropogenic impacts on local ecological equilibrium during different periods of the Holocene. Finally, the role of trapping in the hunting strategies of prehistoric, protohistoric and historic human groups is addressed.

Despite its significant geographic position along the southern corridor into and out of Africa, little is known of the period between 70 and 12 thousand years ago in South Arabia. The existing archeological data come from a handful of lithic surface scatters and buried sites with broad chronological constraints. Here, we report the open-air site of Matafah, a stratified deposit in the Wadi Ghadun drainage system of Dhofar, southern Oman. The accretional terrace discovered at Matafah is composed of low-energy overbank sediments interstratified with cemented layers of fluvial gravels, eolian sands, and hillslope deposits. Three discrete archeological horizons were excavated from the 2.5-m stratigraphic sequence, including Holocene assemblages that overlie a heretofore-unknown assemblage type with geometric microliths. Optically stimulated luminescence age estimates bracket this lower assemblage between 33 and 30 thousand years ago, providing the earliest evidence for the use of projectile armatures in the Arabian Peninsula.

International audience; The northwestern part of Saudi Arabia, being still widely unexplored, is a crucial area to document and understand dispersals and peopling of the Arabian Peninsula by the genus Homo on its way to other parts of Eurasia. We present here the preliminary results of a short survey conducted in 2019 in the vicinity of the modern town of Al-Badʾ, northwestern Saudi Arabia. The lithics from three surface sites, which are located at the foot and slopes of a small jebel of the Al-Rughāmah Mountains present technologically characteristic traits that match other various Middle Palaeolithic industries found across the Arabian Peninsula. The presence of hand-axes and other heavy-weathered artefacts may also indicate an earlier occupation of the region, possibly during the Lower Palaeolithic. The short description of these three newly discovered sites contributes to the growing dataset of Palaeolithic presence in Arabia.

New World archaeologists have amply demonstrated that fluted point technology is specific to Terminal Pleistocene American cultures. Base-fluted, and rarer tip-fluted, projectile points from the Americas have been well-documented by archaeologists for nearly a century. Fluting is an iconic stone tool manufacturing method and a specific action that involves the extraction of a channel flake along the longitudinal axis of a bifacial piece. Here we report and synthesize information from Neolithic sites in southern Arabia, demonstrating the presence of fluting on a variety of stone tool types including projectile points. Fluted projectile points are known from both surface sites and stratified contexts in southern Arabia. Fluting technology has been clearly identified at the Manayzah site (Yemen) dating to 8000–7700 cal. BP. Examination of fluted points and channel flakes from southern Arabia enable a reconstruction of stone tool manufacturing techniques and reduction sequences (chaines opératoires). To illustrate the technological similarities and contrasts of fluting methods in Arabia and the Americas, comparative studies and experiments were conducted. Similarities in manufacturing approaches were observed on the fluting scars of bifacial pieces, whereas technological differences are apparent in the nature and localization of the flute and, most probably, the functional objective of fluting in economic, social and cultural contexts. Arabian and American fluted point technologies provide an excellent example of convergence of highly specialized stone tool production methods. Our description of Arabian and American fluting technology demonstrates that similar innovations and inventions were developed under different circumstances, and that highly-skilled and convergent production methods can have different anthropological implications.

Prehistoric stone structures are prominent and well-studied in the Levantine desert margins. In northern Arabia, however, such structures have received less attention. This article presents the results of investigations of a 35m-long stone platform, first constructed in the mid sixth millennium BC, overlooking the oasis of Dûmat al-Jandal in northern Saudi Arabia. Excavation of the platform has yielded bioarchaeological and cultural remains, along with evidence for several phases of construction and intermittent use down to the first millennium BC. Analysis of the platform and nearby tombs highlights the persistent funerary and ritual use of this area over millennia, illuminating nomadic pastoralist lifeways in prehistoric Arabia.

International audience; Lithic projectile points always had an important diagnostic value for documenting the development and expansion of Arabian Neolithic material culture (c. eighth–fourth millennium BC) and subsistence strategies due to the remarkable abundance of surface assemblages. Given the limitations of traditional arrowhead typology for analysing the increasing variability emerging from archaeological research in the region, we propose here a new systematic description of Neolithic projectile points, based on the consistent observation of technological and morphological change over time and space in a number of diagnostic parameters. A quantitative exploration of variation is carried out on both published and unpublished data through a number of pattern‐recognition techniques and exploratory analyses such as principal component and cluster analysis. By presenting the first application of this approach to Arabian Neolithic projectile points, the research offers a valid tool for investigating temporal and cultural trends through different phases of the Neolithic in the region of interest.

Although Middle Palaeolithic stratified and dated sites are still rare in Arabia, recent archaeological, palaeoenvironmental, population genetic, geomatic and geochronological studies have noticeably contributed to a re-evaluation of the prehistory of the region. Here, we report the discovery of a stratified open-air Middle Palaeolithic site in central Saudi Arabia, a novelty given the paucity of dated Pleistocene lithic assemblages in the region. The site of Umm al-Sha’al is located in the Rufa Graben where a substantial number of Middle Palaeolithic surface occurrences have been reported. It contains artefacts produced using Levallois technology, indicative of Middle Palaeolithic human exploitation of locally abundant quartzite raw material. The site comprises two horizons with archaeological finds dating to Marine Isotope Stages 5 and likely 7 or even older. During this period, hunter-gatherers would have benefited from bodies of water and streams in the vicinity of the site, which were active during humid phases, contributing to the development of a significant biomass. Our discovery supports the hypotheses of an early colonisation of inland Arabia by hominins and of a solid link with North and East African lithic traditions of the Middle Stone Age, which awaits further refinement.

International audience; How have humans colonised the entire planet and reshaped its ecosystems in the process? This unique and groundbreaking collection of essays explores human movement through time, the impacts of these movements on landscapes and other species, and the ways in which species have co-evolved and transformed each other as a result. Exploring the spread of people, plants, animals, and diseases through processes of migration, colonisation, trade, and travel, it assembles a broad array of case studies from the Pliocene to the present. The contributors from disciplines across the humanities and natural sciences are senior or established scholars in the fields of human evolution, archaeology, history, and geography.

International audience; Kites in Armenia were recently discovered, and investigations into their construction, typology and dating are ongoing. With these discoveries, it has become necessary to investigate a series of unsolved questions. In order to test the functions of kites, we conducted a synthesis describing the occurrence and habitat range of Late Pleistocene and Holocene wild ungulates in Armenia. Wildlife is discussed by emphasizing animal behavior and distribution, along with the hunting strategies adopted by the communities that inhabited Armenia. In spite of the fact that wild ungulates did not contribute largely to the daily meat intake or to the major raw products needed by humans since their domestication (around 6000 cal. BC), wild goats, gazelle and red deer were the animals most frequently hunted in Armenia in different time periods and in a variety of landscapes. Hypotheses put forward suggest that these preferences might be linked to using kites as traps for herds at different seasons of the year and on different altitudes, between 3000 and 500 BC.

International audience; In a recent article, Malkinson and his colleagues (Malkinson et al. 2017) have put forward a series of hypotheses on the function, seasonality, and chronology of kites discovered on the slopes of Mount Aragats, in Armenia. Among their hypotheses relevant to function, Malkinson et al. propose that the kites without antennae would have been meant for pastoralism, while those with antennae would have been for large herbivore game. In our opinion, this hypothesis appears to be particularly flimsy: it rests on a very incomplete body of evidence, and does not take into consideration the analysis of the morphological and morphometric aspects of these constructions. The question is whether kites with antennae and kites without them have characteristics that are sufficiently apart from one another to consider different functions.

Kites have often been interpreted as traps built for hunting purposes. This is based on ethnographic parallels, and recurrent references of the habitat range of animals and possible migration routes. Faunal remains from limited zones and from a selection of sites around kites were studied, particularly from northern Syria and eastern Jordan. When considering the wide distribution of kites in the Middle East and Central Asia, some patterns of animal exploitation and hunting strategies are explored in testing the hypothesis of a cynegetic function of the kites across these regions. As a component of the Globalkites project, the zooarchaeological analyses are used to investigate data regarding the function of kites by reconsidering faunal assemblages recorded around their distribution area, as well as by mapping the historical animal distribution in the Near East and Caucasus. The function of kites is discussed on a large scale, through intensive analyses of the subsistence economy, animal habitat and hunting activities carried out by regional human communities. Cross-referencing these variables with the surrounding environment, settlement patterns and animal ethology and their role in ancient societies, leads to an assessment of the current hypothesis on the function of kites.

International audience; The Empty Quarter (or Rub' al Khali) of the Arabian Peninsula is the largest continuous sandy desert in the world. It has been known for several decades that Late Pleistocene and Holocene deposits, representing phases of wetter climate, are preserved there. These sequences have yielded palaeontological evidence in the form of a variety of vertebrate and invertebrate fossils and have been dated using various radiometric techniques. However, evidence for human presence during these wetter phases has until now been ephemeral. Here, we report on the first stratified and dated archaeology from the Empty Quarter, recovered from the site of Mundafan Al-Buhayrah (MDF-61). Human occupation at the site, represented by stone tools, has been dated to the later part of Marine Isotope Stage (MIS) 5 using multiple luminescence dating techniques (multigrain and single grain OSL, TT-OSL). The sequence consists primarily of lacustrine and palustrine sediments, from which evidence for changing local environmental conditions has been obtained through analysis of fossil assemblages (phytoliths and non-marine molluscs and ostracods). The discovery of securely-dated archaeological material at ∼100 to 80 ka in the Empty Quarter has important implications for hypotheses concerning the timing and routes of dispersal of Homo sapiens out of Africa, which have been much debated. Consequently, the data presented here fill a crucial gap in palaeoenvironmental and archaeological understanding of the southern Arabian interior. Fossils of H. sapiens in the Levant, also dated to MIS 5, together with Middle Palaeolithic archaeological sites in Arabia and India are thought to represent the earliest dispersal of our species out of Africa. We suggest that the widespread occurrence of similar lithic technologies across southern Asia, coupled with a growing body of evidence for environmental amelioration across the Saharo-Arabian belt, indicates that occupation of the Levant by H. sapiens during MIS 5 may not have been a brief, localized ‘failed dispersal’, but part of a wider demographic expansion.

Invasive alien species have in recent decades become a major concern in such fields as conservation, agriculture, and medicine. Linked to human mobility, the movements of plants, animals, and microbes have accelerated over the last century, ushering in the new field of invasion biology. Past observers of transported organisms have variously labelled them as exotic, foreign, non-native, alien, and invasive, amongst other terms, depending on the characteristics of the organism and the circumstances and viewpoints of the observer. Historic meanings and connotations of such labels provide insights into changing attitudes toward such organisms, while also providing clues concerning their movement, extent, and number. The shifting labels applied to alien species also emphasizes the subjectivity of these words, and the caution required in employing them, as well as their ability to shape our views of the natural world. Keywords : Invasive alien species, invasion biology, environmental history, etymology, semiotics As the chapters in this volume clearly demonstrate, species move. But as soon as humans become the agent that moves species – accidentally or purposely − by jet, ship, wagon, boot, scalp, or gut, such species are deemed exotic, non-native, introduced, alien . The act of picking up a species and then carrying it along with us forever alters our judgement of it. ‘Alien’ is a term for foreign humans as well as foreign creatures, and if ‘invasive’, such creatures spread on their own after being transported to their new home. Invasive alien plants, animals, and microbes are often considered an irredeemable other, unless they moved by their own means, in which case they are usually considered indigenous. Such native creatures are always home if they can adapt and evolve to new conditions they encounter while moving. If humans were not the ones who transported a creature, then this creature seems to be as suitable as we are – has as many rights as we do – for living in a place. Yet classifying species into alien or native can be controversial. A group of biologists controversially implored colleagues not to judge a species on its origins (Davis et al. 2011), even though not doing so would run counter to the conventions of centuries of categorizing naturalists. Davis’ group explained that while there are certainly undesirable creatures, not all aliens are undesirable.

International audience; For decades, so-called Fasad points have been discovered in Oman and the UAE. These lithic projectile points have been until now fossiles directeurs (or defining artefacts) for Early Holocene human occupation prior to the development of the Arabian Neolithic. It appears that many different types of points are described in the literature as Fasad points, but the actual variability of the archaeological discoveries leads to the necessity for reassessment and clarification of the very definition of this type of artefact. We propose here a new definition of the Fasad points with the creation of sub-types. We also discuss the trend of using this lithic type as a marker for the diffusion of PPNB technology towards the southeast from the Mediterranean Levantine Neolithic core area.

International audience; Since 2013, the authors have conducted archaeological surveys across the Al-Jawf province in northern Saudi Arabia. In the past two seasons, 48 sites were mapped and characterized by the presence of Levallois technology and, therefore, attributed to the Middle Paleolithic of Arabia. Preferential Levallois reduction using different methods of dorsal core preparation have been found at these sites. The technological variability includes Nubian Levallois methods, preferential Levallois with centripetal preparation, as well as recurrent centripetal reduction methods. In Arabia, sites with Nubian Levallois reduction are known from southern Oman, eastern Yemen, and central Saudi Arabia, while in Africa this reduction method has been identified across much of the northeastern continent. Preferential Levallois with centripetal preparation and recurrent centripetal Levallois methods have been found across Saudi Arabia, Yemen, Oman, and the United Arab Emirates. Outside of Arabia, these methods have been found in many regions across the Old World. In this paper, we present the results from technological analyses on the Middle Paleolithic assemblages from the newly discovered Al-Jawf sites. The technological data are used to place these sites into a wider regional framework, assessing whether connections with known lithic industries from across the Near East and northeastern Africa can be surmised.

Dispersals, connectivity and indigeneity in Arabian prehistory

The Shi'bat Dihya 1 site in western Yemen, dated by optically stimulated lu-minescence to 55 ka, provides insight into the Middle Paleolithic peopling of the Arabian Peninsula. The archaeological layer is interstratified within thick, sandy silt floodplain deposits filling a piedmont basin. Luminescence dates, lack of soil development, and gypsum precipitation indicate a high accretion rate of the floodplain during Marine Isotope Stage 3, in connection with a (semi)-arid environment. Rapid overbank sedimentation was likely a result of the remo-bilization of loess material deposited on the Yemeni Great Escarpment at the periphery of the adjacent Tihama coastal sand desert or of other sources. Fabric and size analyses of the lithic artifacts, together with spatial projections, indicate site modifications by floods. Primary modifications include (1) selective accumulation of medium-sized lithic pieces as a result of hydraulic sorting, (2) bimodal orientation of artifacts, and (3) ripple-like arrangement of lithics and bone/tooth fragments. The overrepresentation of teeth may also be a consequence of sorting. Although floods have distorted the original site patterning, long-distance transport of artifacts by water can be excluded, as indicated by relatively high refitting rate, close proximity of artifacts derived from the same block of raw material, and lack of abrasion of the pieces. Therefore, the site is considered " geologically " in situ because its remobilization by water occurred shortly after human abandonment. This study also stresses that the effective preservation of a site cannot be assessed without careful taphonomic study, even in a potentially favorable depositional context such as silty alluvium.

International audience; Major hydrological variations associated with glacial and interglacial climates in North Africa and the Levant have been related to Middle Paleolithic occupations and dispersals, but suitable archaeological sites to explore such relationships are rare on the Arabian Peninsula. Here we report the discovery of Middle Paleolithic assemblages in the Nefud Desert of northern Arabia associated with stratified deposits dated to 75,000 years ago. The site is located in close proximity to a substantial relict lake and indicates that Middle Paleolithic hominins penetrated deeply into the Arabian Peninsula to inhabit landscapes vegetated by grasses and some trees. Our discovery supports the hypothesis of range expansion by Middle Paleolithic populations into Arabia during the final humid phase of Marine Isotope Stage 5, when environmental conditions were still favorable.

International audience; Nubian Levallois technology is the defining characteristic of the Middle Paleolithic or Middle Stone Age technocomplex known as the Nubian Complex. Until recently, this technocomplex was found exclusively in northeastern Africa; however, archaeological surveys conducted across the Arabian Peninsula in the last decade have expanded the known distribution of this technological phenomenon. Since 2009, researchers from separate archaeological missions have mapped sites yielding Nubian cores and debitage, and by extension Nubian technology, in the southern, central and northernmost parts of the Arabia Peninsula. Nubian Complex artifacts in central and southern Arabia were made using different raw materials: in Al-Kharj (central Saudi Arabia) Middle Paleolithic industries were made exclusively on quartzite, while in Dhofar (southern Oman) chert was the only knappable material available for use. Given these differences, we sought to examine the influence of raw material variability on core morphology and size. Contrary to initial hypothesis, this study finds that the differences recorded are not a function of raw material properties. In both areas, Nubian cores were reduced using the same technological systems producing a set of preferential blanks. Rather, the recorded differences from raw material constrains were primarily due to knapping accidents, which occur in higher proportions at quartzite-based assemblages from Al-Kharj (specifically the siret fracture) compared with the chert assemblages from Dhofar. In sum, we argue that raw material had little effect on Nubian Levallois core technology and was not a constraint on Nubian Complex artisans.

International audience; In the last few years, the number of inventoried kites has increased fivefold, and the known distribution zone has been greatly extended across the Near East, Arabia, the Caucasus and Central Asia. High-resolution satellite images provide substantial amounts of data that can be subjected to geomatics analysis. The resulting spatial data is used to identify regional differences.We present here a study of these kite structures at the global, regional and local scales, carried out by means of GIS. The recognition of a number of morphological characteristics, without any subjective attribute, leads to a geographically referenced inventory that clearly distinguishes five main regions. This paper suggests a method to define the morphology of the kites, which will be further augmented with cross-variables including the surrounding environment, settlement distribution, animal exploitation and ethology, providing a base for future studies.

International audience; 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. However, our knowledge of the spatio-temporal distribution of palaeohydrological resources within Arabia during MideLate Pleistocene episodes of climatic amelioration remains limited. In this paper we outline a combined method for remotely mapping the location of palaeodrainage and palaeolakes in currently arid regions that were formerly subject to more humid conditions. We demonstrate the potential of this approach by mapping palaeochannels across the whole Arabian Peninsula, and palaeolakes and marshes for select regions covering c. 10% of its surface. Our palaeodrainage mapping is based upon quantitative thresh-olding of HydroSHEDs data, which applies flow routing to Digital Elevation Model (DEM) data, while our palaeolake mapping uses an innovative method where spectral classification of Landsat Thematic Mapper (TM) imagery is used to detect palaeolake deposits within endorheic (closed) basins, before modelling maximum lake extents by flooding the basin to the level of the elevation of the highest detected deposit. Field survey in the Nefud desert and the Dawadmi and Shuwaymis regions of Saudi Arabia indicates accuracies of 86% for palaeodrainage mapping, and 96% for identifying former palae-olake basins (73% accuracy of classification of individual deposits). The palaeolake mapping method has also demonstrated potential for identifying surface and stratified archaeological site locations, with 76% of the surveyed palaeolake basins containing archaeological material, including stratified Palaeolithic archaeology. Initial examination of palaeodrainage in relation to archaeological sites indicates a relationship between mapped features and previously recorded Palaeolithic sites. An example of the application of these data for period-specific regional palaeohydrological and archaeological reconstructions is presented for a region of Northern Saudi Arabia covering the southern Nefud desert and adjacent lava fields.

International audience; Desert kites are found across a vast region. This paper presents a detailed description of kites from the Harrat al-Shaam region (Jordan) and proposes a comparative study, as well as an analysis of the morphology and organisation of kites known from Mount Aragats (Armenia) and the Ustyurt Plateau (Kazakhstan). A complete inventory of the structures in each region highlights their architectural characteristics and their spatial distribution in the landscape. Some preliminary results were obtained by comparing both regions: the core area in eastern Jordan, and peripheries—sometimes very dis-tant—such as in the Caucasus and Central Asia. Chronological data were also compared , when available. All these different and complementary aspects were finally combined with satellite imagery analyses. The interactive process between satellite images and fieldwork observations has enriched both approaches, while yielding preliminary key elements of interpretation for a better understanding of the kite phenomenon on a global scale.

International audience; Kites are remnants of long stone walls that outline the shape of a child's kite. But the kites are huge, their big size makes them often clearly visible on high-resolution satellite images. Identified at first in the Near East, their area of distribution is getting larger and larger. This wide distribution gives new dimensions in the interpretation of these structures. Consequently, a large scale recognition of kites will help archeologists to understand the functionality of these enigmatic constructions. In this paper, we investigate how the satellite imagery can be exploited in this purpose using a graph representation of the kites. We propose a similarity measure and a kite identification process that can highlights the preservation state of the kites. We also construct from real images a benchmark of kite graphs that can be used by other researchers
