From History to Cultural Diversity: The Changing Roles of the Maya Script as Archaeological Data

From History to Cultural Diversity: The Changing Roles of the Maya Script as Archaeological Data

A New Corpus of Roman Coins from England and Wales. An Overview of the Evidence and Analysis of the Data

Abstract This paper considers a new corpus of 490,154 Roman coins (site finds) which have been recorded from England and Wales. The corpus provides British and regional means to aid in the preparation of coin reports in line with Historic England guidelines, along with spatial data providing new opportunities for research. The methods of data collection will be detailed and some of the possibilities this dataset can provide presented through a number of case studies. Through the consideration of applied numismatic analyses, the social distribution of the material and, crucially, the spatial distribution of Roman coinage, we can identify new trends and patterns. Case studies evaluating the fourth century will emphasise the changing importance of settlements in Roman Britain and identify those linked with the late Roman state. Furthermore, the retraction of coinage distributions in the second half of the fourth century will be explored. Building on the national and site type means explored within the paper, the full dataset has been made available in a range of forms on the Archaeology Data Service and in an interactive map developed by Maploom.

Geology, Archaeology, and Historical Studies of the Late 16th Century Plinian Eruption of Raung Volcano: A Potential Case for Disaster Geotourism in Ijen UNESCO Global Geopark, East Java, Indonesia

The enigmatic major eruption in the late 16th century, believed to have originated from Raung, the most active stratovolcano in the Ijen UNESCO Global Geopark in East Java, Indonesia, has ignited significant debate among researchers and historians due to its profound impact on the region. This research aims to substantiate Raung as the likely source of the major eruption by integrating geological, archaeological, and historical data. This study synthesizes current findings and explores ongoing debates surrounding historical volcanic activities. Eruption parameters suggest that the late 16th century eruption exhibited a Plinian type, characterized by an explosive eruption column reaching the stratosphere, widespread pumiceous tephra fallout, and pyroclastic density current (PDC). Stratigraphic succession reveals that the eruption occurred in five phases, with deposits from 10 eruptive units. These deposits are mainly concentrated on the northwestern flank of Raung. Archaeological findings, historical records, and local legends converge to pinpoint the occurrence of this catastrophic event in the late 16th century. These diverse sources estimate that the eruption resulted in approximately 10,000 casualties, marking it as one of the most significant volcanic disasters in the past 500 years. The implications of this eruption extend beyond historical documentation, providing a critical case study for advancing disaster mitigation strategies through geotourism in the geopark area. Moreover, the eruption record outcrops identified in this study can be proposed as potential new geosites within the Ijen UNESCO Global Geopark, enhancing its educational and touristic value. We propose the Jebung Kidul, Alas Sumur, and Batu Sappar sites as potential disaster-based geosites, considering that these sites record the eruption process and preserve archaeological structures. This addition would not only commemorate the historical event but also promote awareness and preparedness for future volcanic activities in the region.

CONTEXTUAL REANALYSIS OF THE ARCHITECTURAL FORM AND SOCIO-ECONOMIC STATUS OF THE PANAGIA HOUSES AT MYCENAE

The Panagia Houses, one of the building complexes at Mycenae, located to the south-west of the Citadel, were interpreted by the excavators as a group of three independent units. They were constructed and occupied during the Late Helladic (LH) IIIB phase, with two main phases distinguishable in the archaeological record, followed by a reoccupation phase. Careful analysis of the archaeological data published by Mylonas-Shear, which focused on the arrangement of individual units, formality of layout, access and movement patterns, and visibility, suggests that the group should be interpreted rather as a single complex, developed during the period of the maximum expansion of the settlement. The building was gradually expanded to form an extended household, with primary living space surrounded by a number of additional rooms for storage, work and habitation. It was composed of a rectangular main unit, surrounded by an extension formed around a small inner courtyard. The movement between the two levels was organised through a system of connected rooftops, with trapdoors and staircases ensuring access to the various rooms of the complex. During the LH IIIB2 Early phase, Mycenae was hit by a devastating earthquake. Much of the town was left in ruin, but the Panagia Houses were rebuilt, although in a smaller form, with the main unit abandoned and the courtyard inside the extension transformed into the main room of the complex. The status of the complex probably changed, but it was still inhabited by a middle-class family, who possessed a number of valuables and took part in the palatial mobilisation system. The household probably suffered in a widespread fire which destroyed Mycenae at the end of LH IIIB. Its remains were then used as two small dwellings by the survivors of the catastrophe. The history of the complex reflects the changing vicissitudes of the Lower Town of Mycenae.

The Late Bronze–Early Iron Age transition in Canaan: new insights from Bayesian modelling of radiocarbon dates

Scholars have used the emergence of Philistine material culture and the destruction of Canaanite palatial centres as key anchors to archaeologically define the transition from the Late Bronze to the Early Iron Age in Canaan. They have not always, however, agreed on the absolute chronology of these events and its relationship with the historical record. Various hypotheses have been put forward, placing them before, during, or after, the collapse of Egyptian rule and its withdrawal from the region, potentially around 1170–1130 BC. Traditional ‘historicist’ approaches to establishing a chronology for the theoretically linked archaeological layers, have often relied on the assumption that ceramic styles, such as diagnostic artefacts, developed and declined uniformly across different sites. This synchronicity was presumed to mirror historical events as recorded in textual sources — arrival of ‘Sea Peoples’ and the palatial system’s violent collapse. Such a perspective may, however, over simplify the complex regional variations and temporal nuances inherent in the archaeological data. Analysis of multiple radiocarbon datasets from Levantine sites reveals that destructive events and shifts in material culture were not synchronous across the region. Bayesian statistical modelling of these datasets indicates that the timing of such occurrences was influenced by unique local factors, rather than following a uniform regional pattern. The absence of Late Helladic IIIC Aegean-like wares at many sites indicates a geographically restricted production and distribution. Datasets from places where such ware appears reflect the likelihood that their production and exchange occurred from the 13th century to c. 1050 BC. Conversely, the majority of destructive events at key Levantine centres appear to be concentrated within a narrower timeframe, c. 1150–1100 BC. That is, although manifesting at different times and to different degrees of intensity across the region, Philistine presence in the Levant predated most of the Late Bronze Age III destruction events.

Traceology suggests an unexpected use of antler cheekpieces from the Early Iron Age site at Gzin, Poland

Archaeological data confirm the widespread use of horse tack throughout the North European Bronze Age and the succeeding Hallstatt period in an inventory that included metal cheekpieces, phalerae, rein-knobs and other horse-related accessories. Similar usage has been assumed in the region of northern Poland, which has also furnished evidence for the use of horse gear accessories made of antler. This paper reports the results of traceological, isotopic and experimental research on three antler cheekpieces found at the Early Iron Age stronghold of Gzin in northern Poland and relates them further with archaeological and ethnographic patterns of horse exploitation. The results indicate that the artefacts from Gzin have rare comparanda and are isotopically consistent with the δ18Ow range of the site location, which can both be taken as evidence of their local origin. Moreover, traceological and experimental evidence from this study places the function and use of the analysed objects into a new light, undermining their use for horseback riding and suggesting that they were employed as cheekpiece coverings. Combined with the ethnographic record, ceramic iconography and archaeolinguistics, our findings fuel a discussion of deer valorisation during the Lusatian period in Poland, showing that the cheekpieces from Gzin may have served as elements of deer headgear.

Jejak Okupasi Manusia Prasejarah di Situs Gua Batu Baras, Kalimantan Selatan

Batu Baras Cave, located in Bangkalan Dayak village, is an archaeological site in the limestone hill area of ​​Kotabaru Regency, South Kalimantan. Kalimantan prehistoric times have not been established as well as in Java. Recent publications reveal human occupation in the Preneolithic-Paleometallic period in the Kotabaru karst, including in Batu Cave, Cililin Cave 1, Jauharlin Cave 1, and Batu Baras Cave. This article describes the variability of archaeological findings to reveal that human occupation occurred in Batu Baras Cave. Morphological and stylistic analysis aims to illustrate the variety of archaeological data found. We used several approaches to compile the interpretation, including zooarchaeology, paleoanthropology, and spatial. Our result reveals that human occupation in Batu Baras Cave occurred in the early Prenolithic-Neolithic period in 12,402-4,230 calBP. Batu Baras Cave became a dwelling and burial site for the Australomelanesid population in the Preneolithic. The Austronesians inhabited Batu Baras Cave in the Neolithic.

Roman White Marbles in Northern Marche Region (Italy): An Archaeometric Provenance Study

Archaeometric investigations were conducted on Roman marble statues, engraved slabs, and memorial bases discovered in various archaeological sites located in the present Marche Region (Italy), including Fanum Fortunae, Pisaurum, and Potentia. These artefacts are currently housed in the Archaeologic Museum of Fano, the Archaeologic Museum of Pesaro, and the Archaeologic Museum of Porto Recanati (Macerata). Spanning from the Republican age to the Severan dynasty and up until the middle of the fourth century AD, these archaeological artefacts attest to the existence of numerous urbanized Roman colonies adorned with monuments and marble decorations. Mineralogical and petrographic examinations, along with C-O stable isotopic and chemical analyses (MgO and Sr), were carried out to both characterize the marble features and determine their provenance. This research aimed to delineate the specific use and distribution of these marbles across different chronological periods. The results indicated that Proconnesian marble was mainly used in the engraved slabs from Fanum Fortunae, with one exception in which Pentelic marble was identified. The sculptures from Fanum Fortunae and Potentia were carved from white marbles, including Lunense and Parian marbles (Parian-1 and Parian-2 types), with limited use of Pentelic and Thasian marbles, notably the Thasian-3 variety. Memorial bases from Pisaurum were identified to be made from Parian, Proconnesian, and Thasianmarbles. The archaeometric provenance of the different marbles was correlated with the archaeological dating of the artefacts to establish a chronological framework describing their use over time. This work provides an opportunity to appreciate Roman artifacts crafted from precious white marbles, which are housed in various museums throughout the Marche Region. The archaeometric investigation offers a significant contribution to the dissemination of knowledge and serves as a valuable tool for the enhancement of this archaeological and cultural heritage, potentially informing policies aimed at promoting geotourism.

The BIAD Standards: Recommendations for Archaeological Data Publication and Insights From the Big Interdisciplinary Archaeological Database

Abstract This article presents a series of recommendations for the publication of archaeological data, to improve their usability. These 12 recommendations were formulated by archaeological data experts who mined thousands of publications for different data types (including funerary practices, accelerator mass spectrometry dating, stable isotopes, zooarchaeology, archaeobotany and pathologies) during the initial construction of the Big Interdisciplinary Archaeological Database (BIAD). We also include data harmonisation vocabularies utilised for the integration of data from different recording systems. The case studies we cite to illustrate the recommendations are grounded in examples from the published literature and are presented in a problem/solution format. Though practically oriented towards the facilitation of efficient databasing, these recommendations – which we refer to as the BIAD Standards – are broadly applicable by those who want to extract scientific data from archaeological information, those who work with a specific region or theoretical focus and journal editors and manuscript authors. We anticipate that the use of the BIAD Standards will increase the usability, visibility, interoperability and longevity of published data and also increase the citations of those publications from which data were mined. The Standards will also help frame a unified foundation to support the continued integration of the natural sciences with archaeological research in the future.

The rise of the Kaanuˀl kingdom and the city of Dzibanche

Abstract The Kaanuˀl dynasty ruled a hegemonic state with political influence over much of the Classic Maya Lowlands between a.d. 520 and 751. The present article introduces the subject for a special section of the journal, which refocuses attention on the archaeological zone of Dzibanche in southern Quintana Roo, Mexico, where new data are emerging about the origins of the Kaanuˀl dynasty, its urban organization, and its connections to neighboring centers. In this article, we present new data from a recent lidar survey as well as from previous work by Enrique Nalda's Instituto Nacional de Antropología e Historia (INAH) project to reevaluate Dzibanche's characteristics vis-à-vis its rise as a kingdom with far-reaching political influence. We complement these archaeological data with epigraphic information from new monuments and reanalysis of existing ones based on 3D scanning to update the list of Dzibanche rulers. We then revisit the chronology of Dzibanche's royal burials proposing correlations with known Early Classic Kaanuˀl rulers. Overall, the contributions to this special section present new perspectives on the Kaanuˀl's rise to power and its relationship with distant vassals in the crucial period of expansion into northern Peten, leading to the defeat of Tikal and eventually to its transition to a new dynastic seat at Calakmul in the a.d. 630s.

New Observations on the Dionysian Scene Mosaic Panels in the House of the Triumph of Dionysus in Daphne-Antiocheia: Iconographic Description of the Periaktos System in the Decorative Architecture of the Theatre Stage Building

and French teams between 1932 and 1940 uncovered Roman ruins such as a theatre, church and villa. In the publications on the mosaic, the objects on either side of the actors and masks in the L-shaped panels of the Dionysian centre panel in the Dionysian Victory House have been interpreted as boxes and drawers. With this study, it has been seen that the mosaic panel of the Roman villa called “The House of the Triumph of Dionysus”, where a theatrical theme related to the god Dionysos is processed, is the first known iconographic expression of the wooden, prismatic rotating decor system periaktos found in the theatre stage building. We know about the periaktos from the accounts of Vitruvius. Since this decor system was made of wood, it was not possible to find archaeological remains of it. The only archaeological data on the periaktos system is the stone platform on which the periaktos system sits in the stage building of the Kaunos theatre discovered by Prof. Varkıvanç. With this study, the pictorial expression of the stage decor system on mosaics, which we know from Vitruvius’ reports, has also been identified.

Insights into Archaeological and Modern Neotropical Biomes: Examining Diet and Shape Variation through White-Tailed Deer Lower Third Molar

The white-tailed deer (Odocoileus virginianus Zimmermann 1780) holds significant ecological importance across the Americas, both historically and in modern times. This species ranges from southern Canada to Brazil and exhibits polytypic characteristics, adapting well to diverse habitats including temperate, subtropical, semi-arid, rainforest, and savanna environments. In paleontology and archaeology, the comparison of dental characteristics between extant mammal species with known diets is commonly employed to infer the feeding behaviors of their ancient counterparts. This method assumes that extant and fossil species share similar dietary preferences, aiding in the identification of past environmental contexts. Consequently, we employed a multiproxy approach, combining the study of dental wear and 2D geometric morphometrics, to investigate potential relationships between molar shape, diet, and biomes among extant white-tailed deer populations across the Americas. Our analysis included a comparison with archaeological data from Panama. We sampled 274 extant lower second molar specimens for micro- and mesowear analysis, along with 105 lower third molar specimens from natural science museums for 2D geometric morphometric analysis. These were compared with a sample of 65 archaeological specimens from Panama. Our findings revealed distinct variations in the shape of lower m3 molars among extant white-tailed deer populations across different biomes, with notable differences observed in the archaeological samples as well. Micro- and mesowear analyses also indicated biome-related differences, suggesting a general browsing diet for white-tailed deer with nuanced variations across biomes. Mesowear analysis further suggested a dietary spectrum ranging from pure browsers to browser-mixed feeders. These findings offer valuable insights for the interpretation of fossil deer specimens recovered from archaeological sites.

On the Value of Informal Communication in Archaeological Data Work

Abstract Archaeological data simultaneously serve as formal documentary evidence that supports and legitimizes chains of analytical inference and as communicative media that bind together scholarly activities distributed across time, place, and social circumstance. This contributes to a sense of “epistemic anxiety,” whereby archaeologists require that data be objective and decisive to support computational analysis but also intuitively understand data to be subjective and situated based on their own experiences as participants in an archaeological community of practice. In this article, I present observations of and elicitations about archaeological practices relating to the constitution and transformation of data in three cases in order to articulate this tension and document how archaeologists cope with it. I found that archaeologists rely on a wide variety of situated representations of archaeological experiences – which are either not recorded at all or occupy entirely separate and unpublished data streams – to make sense of more formal records. This undervalued information is crucial for ensuring that relatively local, bounded, and private collaborative ties may be extended beyond the scope of a project and, therefore, should be given more attention as we continue to develop open data infrastructures.

ABOUT THE PROTOTYPOLOGICAL ASPECTS OF THE EVOLUTION OF THE DWELLING

Throughout human history, housing has been crucial for human existence, serving as shelter, a symbol of social status, economic prosperity, and cultural identity. Studying archaeological data from different times and peoples has enabled the analysis of the main stages of the development of one of the fundamental values of human material culture - housing. Housing stands as concrete evidence supporting hypotheses and scientific discoveries, offering insights into the life, culture, and traditions of specific epochs. Its extensive evolutionary journey has been shaped significantly by advancements aimed at optimizing living conditions, influenced by societal norms, domestic practices, and scientific advancements. This ongoing evolution has defined housing's architectural characteristics, including differentiation of family, household, functional planning, work, and communal spaces, alongside spatial and expressive architectural elements. It encompasses the development of individual housing units within broader building and settlement frameworks, encompassing diverse housing types and their typological classifications, as well as applying construction and technical methods. This study examines the distinctive typological groups of housing, characterized by their structural underpinnings. These groups are delineated by key factors influencing the inception of formative architectural techniques, such as the early development of functional-planning solutions rooted in familial and regional contexts, and cultural traditions. Additionally, the article explores the architectural evolution of housing, analyzing how prototype components have shaped the phased development of residential functional-planning structures over time. This research contributes to a broader series of investigations into typological evolution of housing, aiming to deepen our understanding of its transformative journey across different historical periods.

Environmental Change Documented in the Fluvial Landscape: A Case Study of the Late Neolithic Bršadin–Pašnjak Pod Selom Site (NE Croatia)

ABSTRACT The formation of Neolithic tell settlements in wetlands or near watercourses is documented in the published literature, but their research is not often based on environmental study. In this paper, we present the results from two sediment cores (BR1, BR2) collected from the case study archaeological site, located on the former bank of one of the Danube's tributaries in the southern Carpathian Basin. Although it has been suggested that a waterlogged environment was deliberately selected for this type of settlement in the regional Late Neolithic, the results of this study, based on both archaeological and environmental data, indicate dry and cool conditions prior and during the initial phase of the settlement formation. The abandonment of the settlement, possibly in the late 5th millennium, probably occurred due to alternating dry and wet episodes, rather than a gradual increase in wet conditions, as suggested elsewhere in the region. A large ditch encircling the settlement, not documented by archaeological research, can be indirectly confirmed by the BR2 core results and the analysis of aerial and satellite images. In general, there is a good correlation of results with the major global climate events, but there are differences in regional and wider south-eastern European context.

Reconstructing palaeogeography and landscapes around the ancient Greek colony of Abdera (Thrace, NE gr.): an integrated remote sensing approach

ABSTRACT We developed a multi-source, integrated remote sensing approach to characterize the geomorphological features of the alluvial and coastal lowlands around the ancient Abdera (coastal Thrace, Gr.). By combining multi-temporal composites of satellite imagery, DEM-derived products, orthophotography, and different cartographic resources, more than 1000 linear km of ancient landforms have been identified and mapped. When crossed with archaeological and historical data, our results allowed to propose a reconstruction of the palaeogeographic evolution and geomorphological dynamics in the eastern lobe of the Nestos Delta, the Kosynthos plain, Lake Vistonida and the Porto Lagos coast since the Antiquity. Our results suggest that the delta developed mainly between Hellenistic times and the Late Antiquity, when it had reached a shape similar to the current. Most of the large palaeochannels visible in the delta seem to be Nestos’ short-lived avulsions occurring in late Byzantine and Ottoman periods. Eastwards progradation of the Kosynthos plain, especially during Byzantine and Ottoman periods and accelerating in the 20th c. due to river channelization, was the main cause of the silting and a significant size reduction of Lake Vistonida since the Antiquity. Lake Lafra was also partially silted in late Byzantine and Ottoman times, likely due to the sedimentary discharge of the Kosynthos after a change in its course. By contrast, other lagoons and wetlands in the coast of Porto Lagos seem relatively stable in the last millennia with only minor silting and coastline progradation. Further geomorphological and geoarchaeological research in the area will allow to draw more precisely long-term interaction of past societies with environmental dynamics and resulting landscape change.

Age and Sex Structure of the Population of the Potapovo and Sintashta Cultures in the Late Bronze Age Based on the Materials of Funerary Monuments from the Volga-Ural Region

The paper analyzes the gender and age structure of the population of the Potapovo and Sintashta cultures in the late Bronze Age based on anthropological materials from a cemetery in the Volga-Ural region. According to archaeological data, both of them belong to a single cultural block; nevertheless, issues of their correlation and primacy in the time of origin are still debatable. 336 markers of gender and age definition in the individuals were applied. Calculations of the main demographic indicators were carried out; histograms of the ratio of age and gender groups were constructed for each culture under consideration. Using the principal components method, an intergroup comparison was carried out on demographic indicators of 31 series in the south of Eastern Europe and Transcaucasia. The indicators of the Potapovo and Sintashta groups have high infant mortality. At the same time, more even ratios of sex and age classes were noted for the Sintashta group of the Trans-Urals. In contrast to Potapovo, a more favorable external and internal social situation for the Sintashta population is assumed. A comparison of demographic indicators against a broader geographical and chronological background demonstrates, firstly, the convergence of the Potapovo and Sintashta groups, the manifestation of similar trends among subsequent series of log culture in the same region, and, on the contrary, sharp differences with the data of the previous pastoral Yamno-Poltavka population. Thus, the demographic indicators of the Potapovo and Sintashta cultures can symbolize the transition to new ethno-cultural living conditions, to the beginning of the formation of stationary geographical points, to the gradual settling of collectives.

Integrating thermal and optical models with legacy excavation data for spatial inventories

Researching at previously excavated archaeological sites comes with its own challenge set, which includes ground-truthing previously unearthed architectural features to correlate old and new trenches. This study presents a comprehensive examination technique to approach architectural features at mound-type archaeological settlements through the synergistic utilization of thermal and optical imagery obtained via remote sensing technologies. Employing an interdisciplinary approach involving various types of imagery (optical, thermal, and radar) embedded in archaeological data, this research aims to reevaluate legacy spatial data and enhance the understanding of subsurface archaeological features by exploiting the complementary advantages of both thermal and optical sensors.This study involves the acquisition, processing, and integration of Unmanned Aerial Vehicle (UAV)-based thermal and optical datasets to derive a complete representation of archaeological landscapes. Ground-truthing and validation exercises are incorporated to ensure the accuracy and reliability of the results. The results contribute to advancing the field of archaeological remote sensing and highlight the significance of integrating diverse sensing modalities for a comprehensive and nuanced interpretation of archaeological landscapes. The techniques exemplified with two mound-type case sites help to generate high-resolution mappings which provide tools to increase the accuracy of on-site legacy data and help digital protection of the sites by generating digital twins. This presents a less costly method than conventional photogrammetric techniques, making it feasible and advantageous for field archaeologists or researchers dealing with legacy spatial data.

Ambiguous landscapes: A framework for assessing robustness and uncertainties in archaeological point pattern analysis.

Landscape research in archaeology has greatly benefited from the increasing application of computational methods over the last decades. Spatial statistical methods such as point pattern analysis have been particularly revolutionary. Archaeologists have used point pattern analysis to explore spatial arrangements and relations between 'points' (e.g., locations of artefacts or archaeological sites). However, the results obtained from these techniques can be greatly affected by the uncertainty coming from the fragmentary nature of archaeological data, their irregular distribution in the landscape, and the working methods used to study them. Furthermore, the quantification of uncertainty in spatial data coming from non-systematic surveys has never been fully addressed. To overcome this challenge, archaeologists have increasingly relied on applying advanced methods from statistics, data science, and geography. While the application of advanced methods from formal sciences will provide robustness to models based on uncertain datasets, as with uncertainty, robustness must be assessed in relation to the case study, the regional context, and the methods used. These issues are of great importance when the models from advanced methods are directly used to create narratives about past landscapes. In this paper, we gather previous research on uncertainty quantification in archaeology and formalize its best practices into a framework to assess robustness and uncertainty in spatial statistical models, particularly focusing on one commonly used in the discipline, i.e., the Pair Correlation Function. This framework allows us to understand better how incomplete data affect a model, quantify the model uncertainties, and assess the robustness of the results achieved with spatial point processes.

Outburst floods and their impact on Chinese Neolithic cultures during the 4.2 ka BP event: Evidence from Dayeze Lake in the lower reaches of the Yellow River

Abrupt climate fluctuations between 4.2 and 3.5 ka BP, and in particular the 4.2 ka BP event, exerted a profound impact on the global ancient civilizations. However, hydroclimatic conditions within the Asian Summer Monsoon (ASM) regions during this event remain uncertain. Here we report a multi-proxy analysis of a sediment core obtained from Dayeze Lake in the lower reaches of the Yellow River in monsoonal China, to elucidate the hydroclimatic variabilities over the past 4.2 ka. Core intervals (4.2–3.5, 1.1–0.6 cal ka BP) containing high levels of sand fraction, low-frequency magnetic susceptibility and zirconium, and low levels of organic matter and calcium oxide, reflect outburst floods from the Yellow River. This is supported by the widespread fluvial deposits and slackwater deposits preserved in archaeological sites and loess-paleosol profiles from the middle and lower reaches of the Yellow River. In contrast, various climate records, such as lake level, pollen, and tree ring data, from the marginal regions of the ASM reflect widespread droughts during the same time period. This finding highlights the significant spatial heterogeneity of hydroclimate within ASM regions associated with the 4.2 ka BP event, which may be related to migrations of the monsoonal rain belt and the West Pacific subtropical high, as well as frequent El Niño–Southern Oscillation events. Referring to archaeological data, we conclude that the decline and collapse of Chinese Neolithic cultures were related to a pattern of droughts in the marginal regions of the ASM and floods in the middle and lower reaches of the Yellow River.
