The province of Van in north-eastern Turkey served as a land bridge between Africa and Eurasia during the Palaeolithic. The region is of particular relevance for understanding the movement of hominins between these continents. This study concerns the lithic remains from a locality at Gürgürbaba Hill, named Locality 010, north of the village of Ulupamir (Erciş district). Locality 010 was dated to 311±32 kya by terrestrial cosmogenic nuclides method, which coincides with Marine Isotope Stage 9 (MIS 9), a Middle Pleistocene interglacial period. The assemblage from this site is attributed to the Late Acheulean and resembles that of the southern Caucasus. This similarity indicates that the artefacts from Locality 010 were probably produced by late Lower Palaeolithic technology in a broad sense. These findings suggest local adaptations of late Middle Pleistocene hominins to high plateau environments.

AbstractThe Ceprano human calvarium, dated around 400,000 yr, is a well-known fossil specimen. It represents significant evidence of hominin presence in the Italian peninsula during the Middle Pleistocene and may be considered representative of an archaic variant of the widespread and polymorphic species Homo heidelbergensis. Since its discovery (March 1994), systematic surveys in the Campogrande area near Ceprano, central Italy, identified 12 localities (CG1-12) with archaeological and/or paleontological assemblages. On this basis, fieldwork was carried out at Campogrande between 2001 and 2006, including drilled cores and excavations, allowing a detailed description of the stratigraphic and paleoenvironmental context associated with the human fossil specimen and the archaeological materials. In the present paper we focus on the stratigraphy and sedimentological features of the uppermost deposits, coupled with a detailed appraisal of the available lithic assemblages that mostly belongs to overlying sediments (CG9 and CG10 localities). We conclude that the Ceprano hominin died in a floodplain environment with a low topographic gradient, where a fluvial meandering channel occurred. The archaeological materials describe a network of sites that document common behavioural features of human groups of the mid-to-late Middle Pleistocene, representing evidence of the regionalization observed across Europe after Marine Oxygen Isotope Stage 12.

AbstractExcavations from 2013 to 2015 at the site of Shishan Marsh 1 (SM1) in the Azraq Basin of eastern Jordan have yielded substantial late middle Pleistocene lithic assemblages in association with faunal remains. Faunal preservation is poor, but multiple taxa have been identified, including cf. Panthera leo, Gazella sp., Bos cf. primigenius, Camelus sp., Equus spp., cf. Stephanorhinus hemitoechus, Palaeoloxodon cf. recki, and Elephas cf. hysudricus. The overall Azraq habitat may have been most similar to a savanna ecosystem, with a mixture of open grassland/shrub habitats and more closed vegetation along the wetlands margins. These taxa were drawn to the relatively lush oasis environment, where they were a dietary resource of the hominin groups exploiting the wetlands resources.

The East Asian monsoon system is an important part of global atmospheric circulation; however, records of the East Asian monsoon from different regions exhibit different evolutionary rhythms. Here, we show a high-resolution record of grain size and pollen data from a lacustrine sediment core of Dajiuhu Lake in Shennongjia, Hubei Province, China, in order to reconstruct the paleovegetation and paleoeclimate evolution of the Dajiuhu Basin since the late Middle Pleistocene (~237.9 ka to the present). The results show that grain size and pollen record of the core DJH-2 are consistent with the δ18O record of stalagmites from Sanbao Cave in the same area, which is closely related to the changes of insolation at the precessional (~20-kyr) scale in the Northern Hemisphere. This is different from the records of the Asian summer monsoon recorded in the Loess Plateau of North China, which exhibited dominant 100-kyr change cyclicities. We suggest that the difference between paleoclimatic records from North and South China is closely related to the east–west-oriented mountain ranges of the Qinling Mountains in central China that blocked weakened East Asia summer monsoons across the mountains during glacial periods.

Abstract Previous investigation of isolated landforms, on the eastern margin of the East Anglian Fenland, England, has demonstrated that they represent an ice-marginal delta and alluvial fan complex deposited at the margin of an ice lobe that entered the Fenland during the ‘Tottenhill glaciation’ (termed the ‘Skertchly Line’). They have been attributed, based on regional correlations, to a glaciation during the Late Wolstonian (i.e. Late Saalian) Substage (Drenthe Stadial, early Marine Isotope Stage (MIS) 6). This paper aimed to test this correlation by directly optically luminescence dating, for the first time, sediments found within the Skertchly Line at Shouldham Thorpe, Norfolk, and Maidscross Hill, Suffolk, together with those in associated kame terrace deposits at Watlington, Norfolk. Ages ranged from 244 ± 10 ka to 12.8 ± 0.46 ka, all the results being younger than MIS 8 with some clearly showing the landforms have been subsequently subjected to periglacial processes, particularly during the Late Devensian Substage (∼MIS 2). Most of the remainder fall within the range 169–212 ka and could be assigned to MIS 6, thus confirming the previously proposed age of the glaciation. The local and regional implications of these conclusions are discussed, the maximum ice limit being linked to that of the Amersfoort–Nijmegen glaciotectonic ridge limit in the central Netherlands.

Abstract The opportunistic debitage, originally adapted from Forestier’s S.S.D.A. definition, is characterized by a strong adaptability to local raw material morphology and its physical characteristics and it is oriented towards flake production. Its most ancient evidence is related to the first European peopling by Homo sp. during Lower Pleistocene starting from 1.6 Ma and gradually increasing around 1 Ma. In these sites a great heterogeneity of the reduction sequences and raw materials employed is highlighted, bringing to the identification of multiple technical behaviours. However, the scientific community does not always agree on associating the concepts of opportunism and method to describe these lithic complexes. The same methodological issues remain for the Middle Pleistocene where, simultaneously to an increase of the archaeological evidence and the persistence of the opportunistic debitage, the first bifacial complexes are attested. Further implications concerning the increasing complexity highlighted in core technology management are now at the centre of an important debate regarding the genesis of more specialized method (Levallois and Discoid) especially during MIS 12 and MIS 9. We suggest that the opportunistic debitage could be the starting point for this process, carrying within itself a great methodological and cultural potential.

This chapter investigates the archaeological landscapes of the frontiers of the Sasanian Empire. Drawing on evidence from current and archived archaeological surveys, in combination with high-resolution remote sensing datasets such as CORONA spy photography, we compare the organisation of settlements and defensive structures of the Sasanian frontier zones in response to a variety of external pressures. These varied from the Roman Empire in the west to less centralised entities, including nomadic groups, in the south-west and north-east. Following a general discussion of the multiple manifestations of Sasanian frontiers drawn from southern Mesopotamia (Iraq), northern Syria and north-eastern Iran, the main focus of the chapter is on the complex frontier landscape of the southern Caucasus, particularly the area of modern Azerbaijan, Georgia and Daghestan. We discuss the role of linear barriers, including the Gorgan Wall in north-eastern Iran and the Ghilghilchay and Derbent Walls in the Caucasus, irrigation systems, and alignments of fortifications and settlements in shaping their local landscapes. By placing the archaeological remains of the Sasanian Empire in a wider context we are able to examine the relationships between military installations, settlement patterns, infrastructure and geographical features such as mountain ranges and rivers. Comparing the different case studies allows us to conclude with some general statements on the nature of Sasanian power in the frontier territories of the empire.

The critically endangered yellow-tailed woolly monkey (Oreonax flavicauda) is endemic to the cloud forests of north-eastern Peru and one of the least studied of all primate species. We conducted fifteen months of group follows using focal animal sampling techniques to gather the first behavioural data on free ranging O. flavicauda. Group follows took place in an area of disturbed primary and regenerating secondary forest near the village of La Esperanza, Amazonas department. Yellow-tailed woolly monkey activity budgets at La Esperanza average: 29.8% feeding, 26.3% resting, 29.0% travelling, 2.3% in social and 12.8% in other activities. Significant differences were observed in the frequency of behaviours between age/sex classes as well as on temporal scales. Our findings are similar to those of other woolly monkey species although yellow-tailed woolly monkeys were found to be more vocally active then other species. We recommend further study of this species at other sites with different forest types to better understand its behavioural ecology and conservation needs. Particular emphasis should be given to studying this species at different altitudes.

Cover sediments of the York Terrace exposed near the California River, western Seward Peninsula, Alaska, yield mollusks, ostracodes, and foraminifera that lived during the Anvilian transgression of early Pleistocene age. The fossiliferous sediments lie at the inner edge of the York Terrace, a deformed wave-cut platform that extends eastward from Bering Strait along much of the southern coast of Seward Peninsula. The seaward margin is truncated by the little-deformed Lost River Terrace, carved during the Pelukian (Sangamonian) transgression. The early Pleistocene sediments seem to have been deposited between the first and second of four glaciations for which evidence can be found in the California River area.The California River fauna includes several extinct species and several species now confined to areas as remote as the northwestern Pacific and north Atlantic. The fauna probably lived in water temperatures much like those of the present time but deeper water on the Bering Shelf is suggested.The presence of an early Pleistocene fauna at the inner edge of the York Terrace at California River shows that the terrace was largely carved before and during early Pleistocene time. However, a marine fauna apparently of middle Pleistocene age is found on the York Terrace near Cassiterite Peak, and this seems to indicate that the terrace remained low until middle Pleistocene time. Uplift of the York Terrace probably was accompanied by uplift of Bering Strait. The strait may have been deeper, and there may have been no land bridge between the Seward Peninsula of Alaksa and the Chukotka Peninsula of Siberia during most of early and middle Pleistocene time.
