This paper describes the morphology of a small piece of the Chalk escarpment near Brook in east Kent, and reconstructs its history since the end of the Last Glaciation. The escarpment contains a number of steep-sided valleys, or coombes, with which are associated deposits of chalk debris, filling their bottoms and extending as fans over the Gault Clay plain beyond. Here the fans overlie radiocarbon-dated marsh deposits of zone II (10 000 to 8800 B.C.) of the Late-glacial Period. The debris fans were formed and the coombes were cut very largely during the succeeding zone III (8800 to 8300 B.C.). The fans are the products of frost-shattering, probably transported by a combination of niveo-fluvial action and the release of spring waters; intercalated seams of loess also occur. The molluscs and plants preserved in the Late-glacial deposits give a fairly detailed picture of local conditions. The later history of one of the coombes, the Devil’s Kneadingtrough, is reconstructed. The springs have effected virtually no erosion and have probably always emerged more or less in their present position. In the floor of the coombe the periglacial chalk rubbles of zone III are covered by Postglacial deposits, mainly hillwashes. They are oxidized and yield no pollen, but contain rich faunas of land Mollusca, which are presented in the form of histograms revealing changing local ecological and climatic conditions. During most of the Post-glacial Period, from the end of zone III until about the beginning of zone VIII, very little accumulation took place on the coombe floor. But below the springs there are marsh deposits which span much of this interval. They yield faunas of considerable zoogeographical interest. The approximate beginning of zone VII a (Atlantic Period) is reflected by a calcareous tufa, which overlies a weathering horizon, and represents an increase in spring flow. Two clearance phases are deduced from the molluscan record. The first may have taken place at least as early as the Beaker Period (Late Neolithic/earliest Bronze Age); the second is probably of Iron Age ‘A’ date. In Iron Age times the subsoil was mobilized and a phase of rapid hillwashing began. As a result the valley floor became buried by humic chalk muds. The prime cause of this process was probably the beginning of intensive arable farming on the slopes above the coombe; a possible subsidiary factor may have been the Sub-Atlantic worsening of climate. The muds yield pottery ranging in date from Iron Age ‘Kentish first A’ ( ca . 500 to ca . 300 B.C.) to Romano-British ware of the first or second centuries A.D. Evidence is put forward for a possible climatic oscillation from dry to wet taking place at about the time of Christ. In the later stages of cultivation, possibly in the Roman Era, the valley floor was ploughed and given its present-day form.

History Of

Research on the late Pleistocene and Holocene environment and archaeology of the upper Kennet valley, north Wiltshire, is described. In concentrating the work in the valley bottom, the main aims were: (1) to see if there was a record of environment and archaeology there, and if so to detail it; and (2) to redress brasses in research towards the visible archaeology of slopes and plateaus and their environmental record.Soils and sediments with biological and archaeological materials covered the late Pleistocene to the present and, with dating by14C and thermoluminescence, enabled a history of environment and human activity to be established.The distinction in hydrology and environment between the valley floor and slopes/plateaus varied with time. In the upper part of the study area at Avebury, there was no stream in the earlier Holocene: woodland covered the valley floor which in some areas was similar to that of the slopes/plateaus in being dry while in other areas it was marshy. In the lower part of the study area at West Overton there was also an earlier Holocene land surface but there were locally streams and swamps, represented by the North Farm Formation. During the earlier Neolithic there was woodland clearance and some cultivation of the valley floor which initiated minor hydrological changes, namely paludification at Avebury and alluviation at West Overton. Dry grassland later developed which was little different from that of the slopes and plateaus. There was no woodland regeneration during the later Neolithic in contrast to the situation in monument ditches on the valley slopes and plateaus. Throughout the study area there was a major episode of alluviation in open country, represented by the West Overton Formation, which was probably initiated in the Beaker period and carried on until the early Iron Age. This, while not putting the valley floor out of use and indeed perhaps enhancing its fertility, provided a very different environment from that of the slopes and plateaus. Another period of alluviation, represented by theArionClay, took place in post-Medieval times.The main Holocene deposits were not wholly allochthonous or made up solely of clastic material derived from slopewash incorporated into the river. Calcium carbonate precipitation accounted for much of the North Farm and West Overton Formations while theArionClay may derive from flocculated material redistributed from watermeadow channels in the course of their management. On the other hand, periods of arable activity in the area, often close to the river valley floor, notably in Iron Age, Roman and Medieval times, have no signal in terms of alluvium.Archaeology, although concealed, is abundant and significantly extends the local record of slopes and plateaus. Mesolithic flints, Neolithic flints and pottery, two lines of probably later Neolithic/Beaker sarsen boulders, later Bronze Age sarsen structures, pottery and a cremation are present on the valley floor, concealed by deposits of the West Overton Formation. Medieval activity, represented on the valley sides as earthworks, extends on to the valley floor where it is concealed byArionClay and earthworks of watermeadows. The visible distribution of archaeology presents a pattern which may be of more than local significance for chalkland areas.

The 19Th Century

The paper is devoted to the results of studies of ancient history on the territory of contemporary Transcarpathian province of Ukraine during the period of it being a part of Czechoslovakia (1919–1939). It was an important stage of establishment of Transcarpathian archaeological science which began its development in the middle of the 19th century from simple collecting of antiquities. In 1929 a county museum was opened in Mukachevo which became an important centre of collection, systematization, and museumification of local artifacts. During that period the ancient history of the region was studied by Czechoslovak archaeologists from the Institute of Archaeology of Czechoslovak Academy of Sciences. Among them, one should name J. Bem, J. Skutil, and J. Eisner. They carried out excavations of archaeological artifacts of the region from different epochs: Paleolithic, Neolithic, Copper and Bronze Ages, Early Iron Age. Due to the efforts of J. Bem collection of Transcarpathian antiquities was systematized, chronology and cultural attribution of numerous material findings were determined. He participated in the excavations at Neolithic and Eneolithic settlements in Nevetlenfolu (Vynohradiv district) and Diyda (Berehovo district) as well as Mala Hora in Mukachevo. Results of the studies enable one to conclude that in the Neolithic epoch this territory was within the area where the culture of linear band pottery was spread. Bearers of this culture practised mattock arable farming, cattle breeding, worshipped the foremother woman. The Stone Age artifacts on the territory of the region were studied by J. Skutil. In the neighbourhood of Berehovo (Mala Hora) and Mukachevo (Kamyanka and Halish hills), he examined a number of Paleolithic locations where he collected several dozens of chalcedony and quartzite objects. They are attributed to the middle and late Paleolithic Age. Local antiquities were also studied by local amateur archaeologists, J. Jankovich, Zatloukal brothers, P. Sova. Having acquired necessary knowledge and recommendations from the Czechoslovak researchers for field studies and documentation of the materials found, they joined the studies of artifacts of an extensive time span – from the Stone Age till Early Mediaeval period. J. Jankovich with the participation of J. Bem performed excavations at a burial mound of the early Iron Age in the village of Kushtanovytsia (Mukachevo district). Two ways of the location of cremation remnants in urns under the mound were documented: at the old level and below it. In 1931 he began the investigation of Slavic mound necropolis in Cherveniovo (Mukachevo district). The excavations revealed cremation burial sites with remnants positioned in urns at the old level or gathered in clusters. The Zatloukal brothers carried out excavations of a ground cremation necropolis in Stanovo (Mukachevo district). The remnants were buried in shallow pits without any external signs and were accompanied by two-three bowls filled with food or favourite things of the decedent. In literature, they are referred to as the Northern-Tysa urn burials of the Late Bronze Age. Key words: settlement, Transcarpathia, burial tomb, Czechoslovakian period.

The Scythians were a multitude of horse-warrior nomad cultures dwelling in the Eurasian steppe during the first millennium BCE. Because of the lack of first-hand written records, little is known about the origins and relations among the different cultures. To address these questions, we produced genome-wide data for 111 ancient individuals retrieved from 39 archaeological sites from the first millennia BCE and CE across the Central Asian Steppe. We uncovered major admixture events in the Late Bronze Age forming the genetic substratum for two main Iron Age gene-pools emerging around the Altai and the Urals respectively. Their demise was mirrored by new genetic turnovers, linked to the spread of the eastern nomad empires in the first centuries CE. Compared to the high genetic heterogeneity of the past, the homogenization of the present-day Kazakhs gene pool is notable, likely a result of 400 years of strict exogamous social rules.

The Gansu–Qinghai region lies in the key position for trans-Eurasian cultural exchange, and hence investigations of the history of agricultural development in this region are significant for understanding the spatiotemporal evolution of prehistoric crop dispersal in Eurasia. However, systematic archaeobotanical studies concerning the history of the development of prehistoric agriculture in this area are scarce. Here, based on archaeobotanical analysis and radiocarbon dating at the Jinchankou site, we investigated the history of agricultural development in the Datong River valley during the Qijia culture. Combined with previous archaeobotanical studies of the Gansu–Qinghai region, we explored the diachronic changes in the cropping patterns from the Late Neolithic to the Early Iron Age. The results suggest that millet remained the most important subsistence plant during 4100–3700 BP, while barley and wheat were first cultivated around 3900 BP at the Jinchankou site. Humans only cultivated foxtail and broomcorn millet in the Gansu–Qinghai region with a high level of agricultural management during 5900–4000 BP. Barley and wheat were added to the agricultural system in the area during 4000–3600 BP, although they played a subsidiary role compared with millet. During 3600–2100 BP, barley played an increasingly important role in the Gansu–Qinghai region but with evident differences among geomorphic units, and there was an obvious decrease in agricultural management level. It is likely that the transformation of cropping patterns and agricultural management levels in the Gansu–Qinghai region from 5900 to 2100 BP was primarily promoted by prehistoric trans-continental cultural exchange and secondly by climate change in the area.

The Bronze Age

In this article I examine how long-term economic strategies in the Bronze Age of northern Europe between 2300 and 500 BCE transformed the environment and thus created and imposed new ecological constraints that finally led to a major social transformation and a "dark age" that became the start of the new long-term cycle of the Iron Age. During the last 30 years hundreds of well-excavated farmsteads and houses from south Scandinavia have made it possible to reconstruct the size and the structure of settlement and individual households through time. During the same period numerous pollen diagrams have established the history of vegetation and environmental changes. I will therefore use the size of individual households or farmsteads as a parameter of economic strength, and to this I add the role of metal as a triggering factor in the economy, especially after 1700 BCE when a full-scale bronze technology was adopted and after 500 BCE when it was replaced by iron as the dominant metal. A major theoretical concern is the relationships between micro- and macroeconomic changes and how they articulated in economic practices. Finally the nature of the "dark age" during the beginning of the Iron Age will be discussed, referring to Sing Chew's use of the concept (Chew 2006).

Despite the important roles that horses have played in human history, particularly in the spread of languages and cultures, and correspondingly intensive research on this topic, the origin of domestic horses remains elusive. Several domestication centers have been hypothesized, but most of these have been invalidated through recent paleogenetic studies. Anatolia is a region with an extended history of horse exploitation that has been considered a candidate for the origins of domestic horses but has never been subject to detailed investigation. Our paleogenetic study of pre- and protohistoric horses in Anatolia and the Caucasus, based on a diachronic sample from the early Neolithic to the Iron Age (~8000 to ~1000 BCE) that encompasses the presumed transition from wild to domestic horses (4000 to 3000 BCE), shows the rapid and large-scale introduction of domestic horses at the end of the third millennium BCE. Thus, our results argue strongly against autochthonous independent domestication of horses in Anatolia.

This article offers an overview of the habitation history of the basin of Ioannina Epirus, from the Early Iron Age to the Roman period. The numerous settlements in this region experienced continuous, often uninterrupted, habitation from the Late Bronze Age to the Hellenistic or even Roman Imperial period. The foundation of fortified settlements/acropoleis in the late fourth to early third century BC should no longer be interpreted as a result of a synoecism, since unfortified villages continued to flourish. From the Augustan period onwards, Romans seem to have settled in the area, although it is also possible that the local population adopted Roman habits.

Excavations of sites spanning the Beaker to early Roman periods at Stackpole Warren, Dyfed, are described. The sites are in an area of blown sand which enhanced their preservation and led to the separation of several horizons. The earliest is a buried soil beneath the blown sand which contained Mesolithic to Bronze Age artefacts. At site A, there was a roundhouse associated with Early Bronze Age pottery and dated to 1620±70 and 1400±70 BC uncal., and two other roundhouses, one possibly of Beaker age. After a period of soil formation, a ritual complex of Later Bronze Age date was established, this contemporary with the earliest besanding of the area; it included a stone setting of more than 2000 small stones, an alignment of small water-worn stones and a standing stone. A cremation gave a latest date of 940±70 BC uncal. Other Later Bronze Age activity is recorded at site G/J in the form of a rectangular enclosure, possibly unfinished.Late Iron Age to early Romano-British settlement was present at sites A and B, consisting of scatters of occupation debris, burnt mounds, cooking pits, hearths and houses, some of stone, some of timber, all taking place in an area being intermittently besanded.Peripheral to the religious and domestic sites, a field system was excavated. The earliest phase was a linear earthwork from which a C14 date of 400±70 BC uncal. was obtained from charcoal in the ditch. After the decay of this, rectangular fields with stone walls were laid out, one along the line of the erstwhile earthwork, this taking place around the end of the Iron Age as dated by C14 of charcoal directly beneath a wall to 90±70 BC uncal. Some of the fields had been cultivated by a succession of cross- and one-way-ploughing, others used for cattle.An assemblage of 763 flints included a few Mesolithic artefacts but was mostly of Late Neolithic and Bronze Age date. A succession of ceramic assemblages included a small Middle Neolithic group (4 vessels), two distinct Beaker groups, one early (Lanting and van der Waals steps 1–3 (8 vessels), one late (steps 3–6) (45 vessels), an Early Bronze Age group of collared urns (43 vessels) and a Later Bronze Age group (26 vessels).Environmental data was not prolific but there was a small quantity of animal bone, mostly cattle and sheep, and cereal grain, mostly barley with some wheat. Marine molluscs were present but sparsely utilized and there was no other indication of the exploitation of the coastal resources such as seals, birds, fish andiseaweed. Land Mollusca indicated open country from the Iron Age onwards when the record begins.The importance of the site is in the ritual complex from site A, the succession of Iron Age/Romano-British occupation horizons, the succession of ceramic assemblages, the field system and the fact that blown sand horizons have allowed the preservation and separation of the sequence much of which would have been at best conflated in to a single horizon or at worst destroyed. Otherwise, there is no evidence that the site was in any way special with regard to the relationship of human activity and sand deposition until the Middle Ages when the area was used as a rabbit warren. Nor was the coastal location important, at least as could be determined by the results. This was a representative of a succession of later prehistoric farming communities and their various domestic, ritual and sepulchral activities in lowland Dyfed.

The stratigraphy of sediments in two lake basins in the Caernarvonshire mountains at 600 and 900 ft. O.D. is described and it is shown that the basal layers were deposited in the Late-glacial Period. The deposits of a third site occupying a kettle-hole in morainic gravels at 1223 ft. O.D. are described and here the Late-glacial Period is not represented. The relation of these sites to the youngest corrie moraines of the district indicates that the latter were formed during the post-Allerod climatic regression (Zone III). The vegetation history of the district was studied by means of pollen analysis of lacustrine deposits from the two first-mentioned sites (above). The vegetation of the Late-glacial Period at first formed tundra (Zone I) in which arctic-alpines, notably Betula , flourished together with species of oceanic and oceanic-northern distribution and calcicolous, eutrophic and moderately thermophilous plants. The spread of juniper scrub preceded the arrival of tree birches, which form ‘park-tundra’ in Zone II at Nant Ffrancon but failed to grow as high as Llyn Dwythwch. The birch ‘ parktundra’ is considered to have covered Britain south of the Forth-Clyde at low altitudes and to have occupied central and eastern Ireland at this time. The climatic deterioration of Zone III is clearly registered by the decline of juniper and tree birch and the local severity of conditions is demonstrated by the increased abundance of the chianophilous fern, Cryptogramma crispa, Lycopodium selago, Saussurea alpina and other montane herbs. The extensive occurrence of solifluxion, augmented by glacier streams, brought down silt and clay into the lakes. The ensuing amelioration in climate and the course of forest development through the Post-glacial Period is briefly traced and the persistence of certain elements of the present mountain flora from the Late-glacial Period demonstrated. A description is given of the spores of Cryptogramma crispa which together with Lycopodium annotinum and Saussurea alpina are new to British Late-glacial records.

Although archaeological analysis emphasizes the importance of climatic events as a driver of historical processes, we use a variety of environmental and archaeological data to show that human modification of the environment was a significant factor in shaping the early history of the Yellow River region of North China. Humans began to modify site-specific and local-level environments in the Early Holocene (~11,500–7000 BP). By the Mid-Holocene (~7000–5000 BP), the effects of humans on the environment become much larger and are witnessed at regional and tributary river basin scales. Land clearance and agriculture, as well as related land use, are dominant determinants of these changes. By the Late Neolithic to Early Bronze Age (~5000–3500 BP), population growth and intensification of agricultural production expanded the human footprint across the Yellow River region. By the Mid to Late Bronze Age (~3600–2200 BP), larger populations armed with better technology and propelled by more centralized governments were altering lands throughout the Yellow River region, gradually bringing the environment under human control. By the Early Dynastic period (221 bc–ad 220), the Yellow River region was an increasingly anthropogenic environment wherein human land management practices were, in many instances, as consequential as natural forces. Throughout the Holocene history of the Middle and Lower Yellow River, anthropogenic, climatic, and natural environmental processes were acting to shape human history and behavior, making it difficult, if not impossible, to say whether human or climate processes were more consequential. There is a complex relationship in China’s early history between natural and human forcing much like there is today. The Early Anthropocene concept is useful here because it recognizes that when natural and cultural forces become so intertwined, it no longer makes sense to separate the two.
