Paul Bishop
Paul Bishop began his undergraduate studies in the School of Earth Sciences at Macquarie University in Sydney, Australia at a time when plate tectonics had begun to revolutionize our understanding of landscape evolution. His doctoral research on the late Cenozoic evolution of the upper Lachlan Valley in the Eastern Highlands of New South Wales, Australia, required an integrated study of the combined impacts of Cenozoic tectonism, vulcanism and er…
When the Land Sings
Geomorphic evidence from rivers and lakes can help explain past changes in the locations of archaeological sites as well as environmental and climatic changes in their catchment areas. Examples drawn from the Blue and White Nile valleys in northeast Africa and from the Son and Belan valleys in north-central India reveal how Quaternary climatic fluctuations in the headwaters of these rivers are reflected in changes in river channel patterns downst…
When the Sahara Was Green
The little-known history of how the Sahara transformed from a green and fertile land into the largest hot desert in the worldThe Sahara is the largest hot desert in the world, equal in size to China or the United States. Yet, this arid expanse was once a verdant, pleasant land, populated by rivers and lakes. The Sahara sustained abundant plant and animal life, such as Nile perch, turtles, crocodiles, and hippos, and attracted prehistoric hunters …

The Khartoum-Omdurman conurbation
Khartoum is one of the largest cities in Africa, located immediately south of the junction of the Blue and White Nile rivers in central Sudan. The growth of the Greater Khartoum-Omdurman conurbation arosewithout a proper urban planfrom the agricultural wealth created through the completion of three dams, and mostly in the last three decades. Urban expansion was enabled by and helped to enhance the major agricultural expansion of the Gezira clay p…
Identifying disturbance in archaeological sites in tropical northern Australia
The stratigraphic integrity of archaeological deposits in the seasonally wet tropics can be disrupted by termite activity and other processes. Significant questions have been raised about the surprisingly old age estimates for artefacts recovered from two sites in northern Australia: Nauwalabila and Madjedbebe. If accurate, a 65,000‐year date for the latter would represent a 30% increase in the currently accepted length of human occupation of the…
The Nile Basin
The Nile Basin contains a record of human activities spanning the last million years. However, the interactions between prehistoric humans and environmental changes in this area are complex and often poorly understood. This comprehensive book explains in clear, non-technical terms how prehistoric environments can be reconstructed, with examples drawn from every part of the Nile Basin. Adopting a source-to-sink approach, the book integrates events…
When did Homo sapiens first reach Southeast Asia and Sahul?
Anatomically modern humans ( Homo sapiens , AMH) began spreading across Eurasia from Africa and adjacent Southwest Asia about 50,000–55,000 years ago ( ca . 50–55 ka). Some have argued that human genetic, fossil, and archaeological data indicate one or more prior dispersals, possibly as early as 120 ka. A recently reported age estimate of 65 ka for Madjedbebe, an archaeological site in northern Sahul (Pleistocene Australia–New Guinea), if correct…

Preliminary investigation of Indigenous campsites in late Quaternary dunes, Port Augusta, South Australia
A series of late Quaternary dunes are located in the vicinity of Port Augusta in the mid-north of South Australia. Observations of deflating archaeological material were first recorded by Norman B. Tindale during the 1939 Harvard- Adelaide University Anthropological Expedition (Tindale 1939:827).        A mile & 3/4 beyond the Port Augusta Bridge on the side of the road to Iron Knob, we hunted over a site where we had on a previous occasi…
Interactions of Desertification and Climate
Stable carbon and oxygen isotopic composition of early-Holocene gastropods from Wadi Mansurab, north-central Sudan
The 8500- to 7000-year-old shell-bearing sediments in shallow claypans near Wadi Mansurab in north-central Sudan appear to reflect a widespread and much wetter period in northeast Africa. Stable carbon and oxygen isotope analysis of the Wadi Mansurab gastropods reveals that the shell carbonate is highly depleted in 13 C and 18 O. The highly depleted oxygen isotopic composition is indicative of rainfall derived from a distant oceanic source. The h…
New Geochemical Evidence for the Youngest Toba Tuff in India
New geochemical data on tephra samples from a layer present at several archeological sites in India support correlation of this layer to the Youngest Toba Tuff, erupted from northern Sumatra about 74,000 yr ago. The data show that the Indian tephra layer is not a correlative of older tephra erupted from Toba, as has been suggested on the basis of artifact assemblages. Previously published geochemical data on the Indian tephra beds was based on bu…

Evidence for the Dissolution of Magnetite in Recent Scottish Peats
Magnetic, hydrological, and geochemical data for 11 Scottish peat cores confirm previous reports that anthropogenic pollutants constitute the principal source of ferrimagnets to such environments, but indicate that postdepositional Fe 3 O 4 persistence may be more limited than formerly envisaged. In all cores, the lower stratigraphic limit of magnetic enrichment coincides with the water table, below which negative mV values and enhanced ratios of…

More important, we are a society devoted to a body of music, some of which has had considerable influence in the world, some of which has gained considerable respect, and some of which has an originality that might fill us with pride as Americans and with curiosity and dedication as scholars. Our music, in short, also implies certain responsibilities. In this century the profession of musicology has strayed into a kind of relativism in which it i…

Jazz
It is generally agreed that in the decades of the 1920s and 1930s there were important developments in jazz centered in City. City had been the home of the Bennie Moten orchestra since the early 1920s; it gave us the Count Basie orchestra with Lester Young in the mid-1930s; and it nurtured Charlie Parker before he came to national prominence in the 1940s. Such a city, such a musical environment, obviously warrants our attention. So far it has bee…

On becoming human
Only in Africa have Pliocene hominid fossils been recovered so far. The oldest well‐dated Australopithecine fossils come from the Middle Awash valley of Ethiopia and are 4 million years old. The earliest evidence of stone toolmaking, from the same region, dates to c. 2.5 million years ago, which was a time of cooler, drier climate in the Ethiopian uplands, and of rapid ice build‐up in the northern hemisphere. By 1.5 million years ago Homo erectus…

Where Plain and Plateau Meet
We had three initial aims: to determine the depositional history of river, creek and shelter; to relate any excavated faunal remains to associated cultural material; and to establish a well-dated cultural sequence for this site paying due attention to spatial variation within the shelter. A final aim was to see how far our results confirmed or opposed conclusions drawn from other and earlier work in this geographical region

The Physiography of the Central Sudan
The geological history of the Nile in the Sudan has been reviewed comprehensively by Berry and Whiteman (1968), Butzer and Hansen (1968), and more recently by Whiteman (1971). Recent fieldwork by the authors in central Sudan has more than trebled the number of radiocarbon dates available from that region, and has added significant detail to knowledge of the age and origin of the Gezira plain and the late Quaternary history of the Blue and White N…

The Efficacy of Creep and Slopewash in Tropical and Temperate Australia
Recent Expeditions to Libya from the Royal Military Academy, Sandhurst
South-east libya, one of the driest regions of Africa (Gautier, 1950; Hume, 1925, p. 79; Ball, 1939, p. 36), is administered from the oasis of Kufra, to the north of which lies the barrier of the Calanscio Sand Sea extending westwards to join the Rebiana Sand Sea. Two routes pass through the uninhabited desert to the south of Kufra. The route to Chad is provided with two deep wells, Maaten Bisciara and Sarra, each about 150 kilometres apart and d…

When Louis Armstrong first arrived in the early 1920s, the reaction of his fellow musicians was generally positive. His elders, most of them, and particularly if they were from New Orleans, heard him as a fulfillment of what they had been working on. And younger players seem to have felt that here was someone who could serve as an inspiration and guide, from whom they could take at least a part, if not all, and develop something of their own. Whe…
