Stable isotope dietary analysis of prehistoric populations from the Minusinsk Basin,Southern Siberia,Russia: a new chronological framework for the introduction of millet to the eastern Eurasian steppe

We report the results of stable carbon and nitrogen isotope analysis of 354 human and faunal samples from five archaeological cultures of the Minusinsk Basin, Southern Siberia – Afanasyevo, Okunevo, Andronovo, Karasuk and Tagar (ca. 2700–1 BC) – a key location in Eurasia due to its position on a northern corridor linking China and central Eurasia. The results indicate that the diet of Eneolithic to Middle Bronze Age (Afanasyevo to Andronovo) populations was primarily C₃-based, with C₄ plants only becoming an important component of the diet in the Late Bronze Age Karasuk and Early Iron Age Tagar cultures. Freshwater fish seems to have been an important constituent of the diets in all groups. The findings constitute the earliest concrete evidence for the substantial use of millet in the eastern Eurasian steppe. We propose that it was probably introduced from Northwestern China during the Karasuk culture at the start of the Late Bronze Age, ca. 1500 BC. We conclude with a discussion of the implications for the nature of pastoralist economies on the steppes.     

Lower Devonian ischnacanthid fish (Gnathostomata: Acanthodii) from the Taemas Limestone,Lake Burrinjuck,New South Wales

Dentigerous jawbones of ischnacanthid acanthodians from the Lower Devonian Currajong Limestone Member and the lower part of the Bloomfield Limestone Member of the Taemas Limestone (Murrumbidgee Group: early Emsian) in the Murrumbidgee valley at Good Hope, Taemas district, and the Goodradigbee valley at Wee Jasper are described. Three taxa of Taemasacanthus are recognized: T. sp. cf. erroli Long, 1986; T. narrengullenensis sp. nov. and T. cooradigbeensis sp. nov. Fragmentary fin spine remains and scales are also described.     

The Importance of Home-Area Studies for Soviet Geography

The article discusses the Soviet Union's nation-wide program of krayevedeniye, a Russian term that is difficult to translate but equivalent in meaning to the German Heimatkunde. The English “home-area studies,” though admittedly unsatisfactory, has been used to avoid foreign terms. The Soviet home-area study program includes amateur studies by local residents, school-sponsored studies to acquaint students with their school district, and government-directed study programs centered on regional museums.     

The Role of Eastern Siberia in Solving Some of the Economic Problems of the Pacific Basin

The abundance of resources in the Soviet Far East and Eastern Siberia, combined with the known scarcity of fuel and energy supplies and certain raw materials in the countries of the Pacific basin, suggests that the resources of the eastern regions of the Soviet Union, could, if properly developed, find a wide market in countries bordering on the Pacific Ocean.     

The Aral Sea Problem and its Solution

A hydrogeologist suggests that nine-tenths of the present stream flow into the Aral Sea can be diverted for other purposes without causing the sea to dry up. The diversion would cause the sea level to drop by 12 meters, where it would stabilize because of a greater intake of subsurface runoff resulting from an increased artesian pressure differential, and because the draining of flooded shore areas and the drying up of reed growths will make more water available through savings in evaporation and transpiration.
