Abstract:

An accumulation of iguanian bone remains was found inside a rodent burrow in an Holocene archaeological site of the Argentine southern Puna. Characters of the preserved bones suggest that a minimum of two species of the Liolaemus genus is represented. One of them is undoubtedly attributed to the montanus group, probably L. poecilochromus or L. andinus. The finding of Liolaemus bone remains in the Argentine Puna Region represents the first record of this genus in an archaeological site of South America and suggests that specimens of at least two Liolaemus species exploited the same refuge simultaneously, including both adult and juvenile individuals.

Abstract:

The survey of natural profiles comprising thin interspersed volcanic and peat banks along different ecological zones and altitudinal levels in western Tinogasta (Catamarca Province, Argentina) provides an insight into the natural environmental conditions for the past human activities in these areas. The geological analysis integrated to the archaeological data allows the proposal of climatic fluctuations, explosive volcanism and, probably recurrent, seismic activity influencing the low and null occupation intensity of the highlands and lowlands, respectively, during the Mid-Holocene (8000-4000 BP). These conditions generated unstable environments that prevented the continuous and sustained occupation of the ecological zone of the Chaschuil Valley highlands (3500-4000 masl), and hindered the occupation of the lowlands in the mesothermal valleys of the Fiambalá region (1400-2400 masl). The products of explosive volcanism caused changes in topography which, along with other factors, had different impacts on the productive populations occupying the region since the first century AD.
