Early Pleistocene human occupation at the edge of the boreal zone in northwest Europe

The dispersal of early humans from Africa by 1.75 Myr ago led to a marked expansion of their range, from the island of Flores in the east to the Iberian peninsula in the west. This range encompassed tropical forest, savannah and Mediterranean habitats, but has hitherto not been demonstrated beyond 45° N. Until recently, early colonization in Europe was thought to be confined to the area south of the Pyrenees and Alps. However, evidence from Pakefield (Suffolk, UK) at ∼0.7 Myr indicated that humans occupied northern European latitudes when a Mediterranean-type climate prevailed. This provided the basis for an ‘ebb and flow’ model, where human populations were thought to survive in southern refugia during cold stages, only expanding northwards during fully temperate climates. Here we present new evidence from Happisburgh (Norfolk, UK) demonstrating that Early Pleistocene hominins were present in northern Europe >0.78 Myr ago when they were able to survive at the southern edge of the boreal zone. This has significant implications for our understanding of early human behaviour, adaptation and survival, as well as the tempo and mode of colonization after their first dispersal out of Africa.

Human Burial Evidence from Hattab II Cave and the Question of Continuity in Late Pleistocene–Holocene Mortuary Practices in Northwest Africa

Archaeological excavations in 2002-3 at Hattab H Cave in northwestern Morocco revealed all undisturbed Late Palaeolithic Iberomaurusian human burial. This is the first Iberomaurusian inhumation discovered in the region. The skeleton is probably that Of a male aged between 25 and 30 years. The individual shows a characteristic absence of the central upper incisors reported in other Iberomaurusian burials. Accompanying the burial are a stone core and a number of grave goods including bone points, a marine gastropod and a gazelle horn core. Thermoluminescence dating of a burnt stone artefact in association with the burial has provided an age of 8900 +/- 1100 BP. This is one of the youngest ages reported for the Iberomaurusian and raises questions about persistence of hunter-gatherer societies in the Maghreb and the potential for continuity in burial practices with the earliest Neolithic.

An Imperial Frontier of the Sasanian Empire: further fieldwork at the Great Wall of Gorgan

Abstract The 2006 season has yielded significant new insights into the Great Wall of Gorgans relation to landscape features and settlement, notably the division of the associated complex water supply system into sectors. The westernmost part of the wall is buried deeply beneath sediments from a past transgression of the Caspian Sea. An unexpectedly high number of brick kilns, of standardised design, shed light on the manner of the walls construction. Geophysical survey, satellite images and excavations have established that some or all of the associated forts were densely occupied with buildings, thought to be barracks, suggesting a strong military garrison.

Linear barriers of northern Iran : The great wall of gorgan and the wall of tammishe

Le grand mur de Gorgan, appele aussi mur d’Alexandre ou mur de Feroz, est une vaste structure defensive de pres de 200 km de long, entre la Mer caspienne et la chaine de l’Elbrouz. La date de sa construction est controversee, et elle varie selon les auteurs sur une plage chronologique allant de la conquete macedonienne a la conquete islamique. Le projet porte par l’universite d’Edimbourg, l’Iranian Cultural Heritage et l’organisation du tourisme du Golestan consistait a trancher la question de la datation du Grand mur de Gorgan et du mur de Tammishe en utilisant les methodes modernes de prospection archeologique et de datation absolue. Ces recherches ont revelees l’existence de structure hydrauliques mais surtout, les methodes de datation au radiocarbone et par luminescence stimulee optiquement (OSL) ont permis de cerner avec une grande precision la date de ces monuments. Ils ont ete eriges autour du Ve siecle de notre ere, donc vraisemblablement par l’empereur Sassanide Feroz, pour proteger l’empire des Huns Hephtaliques.

Holocene environmental changes in the Lower Thames Valley, London, UK: Implications for understanding the history of Taxus woodland

A radiocarbon-dated multiproxy palaeoenvironmental record from the Lower Thames Valley at Hornchurch Marshes has provided a reconstruction of the timing and nature of vegetation succession against a background of Holocene climate change, relative sea level movement and human activities. The investigation recorded widespread peat formation between c. 6300 and 3900 cal. yr BP (marine ‘regression’), succeeded by evidence for marine incursion. The multiproxy analyses of these sediments, comprising pollen, Coleoptera, diatoms, and plant and wood macrofossils, have indicated significant changes in both the wetland and dryland environment, including the establishment of Alnus (Alder) carr woodland, and the decline of both Ulmus (Elm; c. 5740 cal. yr BP) and Tilia (Lime; c. 5600 cal. yr BP, and 4160–3710 cal. yr BP). The beetle faunas from the peat also suggest a thermal climate similar to that of the present day. At c. 4900 cal. yr BP, Taxus (L.; Yew) woodland colonised the peatland forming a plant community that has no known modern analogue in the UK. The precise reason, or reasons, for this event remain unclear, although changes in peatland hydrology seem most likely. The growth of Taxus on peatland not only has considerable importance for our knowledge of the vegetation history of southeast England, and NW Europe generally, but also has wider implications for the interpretation of Holocene palaeobotanical records. At c. 3900 cal. yr BP, Taxus declined on the peatland surface during a period of major hydrological change (marine incursion), an event also strongly associated with the decline of dryland woodland taxa, including Tilia and Quercus, and the appearance of anthropogenic indicators.
