First discovery of the ancient dingo-type dog in Polynesia (Pukapuka,Cook Islands)

A Dingo-type dog skeleton was excavated in Pukapuka Island of the Cook Islands with an estimated age of about 350 years. Luomala (1960) suggested that an investigation of the breed of Polynesian dogs would provide clues to the history of migration of the Polynesians, who domesticated the dogs. The Pukapuka dog skeleton is morphologically similar to the dingo and suggests some racial or economical interchange among Australia and Polynesian islands before contact with western civilization.     

Saints and Sinners: a tephrochronology for Late Antique landscape change in Epirus from the eruptive history of Lipari,Aeolian Islands

Assessing the impact of past human activity on landscape change in the Mediterranean has always presented challenges, requiring sound chronological frameworks for observed environmental change. The current research, focused on the environs surrounding the ancient city of Butrint (southern Albania) during Late Antiquity, c. 4th–6th Century AD, establishes a tephra-based chronology for landscape change through the discovery of ash horizons from a little known eruption on the island of Lipari (Aeolian Islands). Recovered glass shards were geochemically fingerprinted to a 6th Century AD event on the island, dated through local archaeological sequences and corroborated by hagiographic evidence. The presence of this marker horizon at Butrint shows a continuation of open water, estuarine conditions throughout Late Antiquity and the Early Medieval period (during which time Butrint ceases to function as an urban centre), disproving the widely held notion of increased soil erosion/deposition as a result of post-Roman landscape degradation. The study also shows that it is following the medieval revival of the town in the 13th Century that marked environmental change takes place, as estuarine areas silt, giving rise to marsh and wetland. The study highlights the importance of using a range of dating techniques to constrain landscape change, while the presence of the 6th Century Lipari tephra in Epirus, derived from an eruptive event larger than previously suspected, provides a useful regional dating marker for future landscape studies.     

关于魏晋墓砖壁画色彩保护的探索

Investigation of ancient noodles,cakes, and millet at the Subeixi Site,Xinjiang, China

Ancient foodstuffs, including noodles, cakes, and common millet, were excavated from the Subeixi Cemeteries (cal. 500–300 years BC), Turpan District in Xinjiang, China. Starch grain and phytolith analyses were undertaken to identify the plant species involved. These indicate that the noodles and cakes were made from Panicum miliaceum. Ancient food preparation technologies were also investigated by cooking experiments.     

A Note on the Results of Recent Excavations at Camber Castle,Sussex

Abstract

A significant number of clay tobacco pipes in the style of the Ottoman ‘chibouk’ can be found in museums and private collections on the islands of Malta and Gozo. Indeed the smoking of these pipes remains a folk memory with the majority of senior citizens. It became obvious that very few of these artefacts were made locally and that the Maltese, being at the geographical centre of Mediterranean culture, might have received their imports from anywhere.

In 19th-century Tunisia (Malta’s nearest North African neighbour) three-quarters of the European population were Maltese migrants. Therefore, this study set out to discover whether Tunisia was a source of supply.

In Tunis it became obvious that although clay tobacco pipes had turned up in local excavations, little attention had been paid to them and a fuller examination was welcomed. A by-product of this examination was to establish a locally made Tunis pipe, although little evidence was found for trade to Malta in that particular commodity.     

Promotion of a neglected heritage at Stone Age sites in the Western Cape,South Africa

Abstract

All archaeological sites in South Africa are protected in terms of the National Monuments Act, yet some have been badly damaged by vandals, unauthorized collectors and the effects of natural and anthropogenic erosion. In an effort to minimize such damage, the policy in the past has been either to restrict access or to keep a low profile, in relation both to rock art and excavated sites. Coupled with the fact that, in the past, the precolonial period has not been included in school history curricula, this policy has had a negative effect. South Africans generally have a limited knowledge of the results of research on rock art and archaeology and are not aware of the legislation. Furthermore, there is no infrastructure and no market for promoting such sites for tourism. The National Monuments Council has identified the need for public education in this field within a broader goal of promoting a common heritage for all South Africans in this time of political change. Three examples of recent active intervention are given in this paper. Stone Age living sites at Nelson Bay Cave and Matjes River rock shelter have been developed as local attractions, and protective conservation measures have been put into practice at rock art sites that are open to the public in the Western Cape.     

A group of 20 stone anchors from the waters of Dwarka, on the Gujarat Coast, India

A large number of stone anchors were discovered in a water depth of 10–14 m off Dwarka during the 1998–99 season. The seabed near the anchors consists of a ledge with an average height of 1 in. Several anchors were found trapped between the rocks suggesting an anchorage. Twenty stone anchors of three types were loacted in a submerged channel on the southern side of the site. The grapnel type of anchor is associated with Indo-Arab trade between the 8th and 16th centuries AD. The triangular or composite anchors have a date ranging from 2500 BC to the Modern Period. Therefore, the dating of these anchors at Dwarka is a matter of concern and is discussed.

New Data on the Relief Development of the South Shetland Islands,Antarctica

Abstract

During several expeditions to the Antarctic Peninsula and the neighbouring islands, samples were collected from different sediments which contained datable materials or which were datable with new techniques. Thus it became possible to develop, together with our geomorphic field data, some new ideas on relief development at the rim of the Antarctic continent as well as on the glacial history of the area studied.

Planation surfaces in this area seem to be fairly old. For example, the prominent marine erosion surface on Fildes Peninsula, 35–45 m above mean sea level, is probably older than 85 000 years – older than the last interglacial period and the penultimate glaciation. All Holocene beaches, which are situated between 20 m and the present coastline, were formed during the last 6000 years.

Before 6000 BP the islands were still completely glaciated. The breakdown of the ice cover to nearly the present extent must have been extremely abrupt, taking no more than 1000 years (6000 to 5000 BP). Between 3000 and 1000 BP there were at least two re-advances. These advances were restricted to the prominent outlet glaciers, which followed pre-existing valleys.     

Seasonal Patterns of Coastal Exploitation on the Farasan Islands,Saudi Arabia

Here we present the results of the analysis of coastal exploitation patterns in the southern Red Sea during the Middle Holocene. We focus on the shell midden cluster of the Farasan Islands, Saudi Arabia, which comprises over 3,000 shell midden sites. These sites date from 6,500 to 4,500 cal BP and are part of an arid landscape. We focus on one site, JW1727, which provides a snapshot of marine exploitation and will help to understand the use of food resources within the region. Stable isotope values (δ¹⁸O) were collected from the marine gastropod Conomurex fasciatus (Born 1778), which represents 72% of shell weight of JW1727, in order to reconstruct the season of capture. Results demonstrate that 1) every season is represented within the dataset; and 2) there is increased C. fasciatus deposition during the summer and autumn months. This indicates a diet consisting of C. fasciatus throughout the year in combination with other food sources and an increase of the C. fasciatus component during the arid seasons, possibly linked to the unavailability of vegetation. Additionally, size measurements of C. fasciatus were carried out to examine changes in size distribution throughout the occupation of the site that could be related to overexploitation of C. fasciatus. However, no significant trends could be observed. In sum, the results suggest a sustainable and constant habitation of the Farasan Islands despite the highly arid conditions.     

Technology,chronology and the role of crucible steel as inferred from iron objects of the ancient site at Junnar,India

Ordinary iron objects from an ancient habitation site at Junnar in India, dating to the 2nd BC to AD 2nd century, were examined for their microstructure, chemical composition and age. The objects were mostly made of high carbon steel with a homogeneous microstructure consisting of fine spherical particles of carbide in the ferrite background, free of non-metallic inclusions. Their carbon concentration ranged from 0.7% to over 1.6% with one exception at 0.2%. Some of them contained trace amounts of silicon, manganese and sulfur while one object retained cavities due to volume contraction during solidification reactions. These features indicate that the objects examined constitute an early example of Indian steel making in crucibles. Evidence was found that basic techniques needed for the success of crucible steel technology were mostly available at Junnar at the time. The radiocarbon measurement on carbon samples extracted from one of the iron objects placed its date between 176 BC and AD 20, in agreement with the radiocarbon dates of three charcoal samples from the same site. The forgoing results support that crucible steel was produced in India at a much earlier date than previously supposed, to serve as a material for specific needs arising in daily life.
