ABSTRACT Camelids were domesticated in the Andean highlands, such as in the puna habitat, and dispersed into lowland areas and the northern Central Andes. As camelids domesticated in a particular region would have had a greater economic benefit than visiting- or hunted wild camelids, it is important to reconstruct the dispersal of camelid husbandry from its initial site throughout the ancient Andean civilisation. We carried out multi-isotope analyses of animal remains recovered from the Pacopampa site to investigate the nature of camelid pastoralism and utilisation. Strontium and oxygen isotope ratios from tooth enamel suggested that camelids in the early Late Formative Period (800–500 BC) were born near the site and remained in the same habitat for up to three years. Although corresponding data for the Middle Formative Period (1200–800 BC) were not available, carbon and nitrogen isotope ratios were statistically different from those of the Late Formative Period, supporting the possibility that the camelids inhabited the highland plateau like puna. It is inferred that in the northern highlands camelids were initially rare and regarded as either tribute or ritual animals, or they were used as pack animals. Camelid husbandry using maize as fodder began during the Late Formative Period at Pacopampa. 相似文献

Attirampakkam, an open-air stratified Palaeolithic site in southeastern India is the focus of ongoing studies to investigate the nature of Lower and Middle Palaeolithic occupation in relation to changing Pleistocene environments. The paucity of faunal or palaeobotanical remains at the site required the use of rock magnetic properties (χlf, χfd, χfd %, χARM, SIRM, χARM/SIRM, SIRM/χlf, χARM/χlf, χARM/χfd, S-ratio, HIRM and HIRM/IRM300mT) as proxies for deciphering the palaeoenvironments and palaeoclimates of the region. Rock magnetic data from stratified deposits within excavated trenches show that the bulk of the sedimentation was intermittent with no subaerial exposure of sediments for long periods, and points to fluctuating wetter and drier climates associated with the Acheulian to Late Middle Palaeolithic levels. There is a general trend towards a wetter climate from Layer 5 upwards. Layer 7 offers evidence of bacterial magnetite (χARM/χlf > 40 and χARM/χfd > 1000), suggesting the onset of micro-anaerobic environments as a result of floods. Greigite is indicated in Layer 5 (SIRM/χlf > 30 × 103 A m?1), which indicates a reducing environment. Layer 2 represents an arid climate (higher proportion of haematite and a coarser magnetic grain size). Layer 1a again is indicative of an arid climate (presence of calcrete, magnetically “hard” minerals and coarser magnetic grain size). Results indicate that the southeast coast of India experienced a mostly dry tropical climate during the Pleistocene. The detected occurrence of a few notably more arid intervals did not disrupt occupation of the site by successive groups of hominins. 相似文献
