Livestock management at the Late Iron Age site of Baltarga (eastern Pyrenees): an integrated bio-geoarchaeological approach

Abstract

Despite the important role of livestock farming amongst Iron Age communities living in mountain regions, there is little information about livestock management, and particularly stabling practises, breeding systems, and grazing/foddering patterns. The study of the ground floor of Building G in Tossal de Baltarga has provided valuable insights into these important issues and has given us a better understanding of the social and economic patterns involved in all these livestock activities. It revealed the existence of a stable from the Late Iron Age, thanks to unique in situ finds of the stabled animals, including four sheep, a goat, and a horse, in addition to a range of organic remains preserved by fire and penning deposits. It is the first documented to date in the northeastern Iberian Peninsula. Through an integrated bio-geoarchaeological approach, combining a range of analytic procedures, including osteology, dental microwear, stable isotopes, phytoliths, dung spherulite analyses, and thin-section micromorphology, for the first time, this study has provided new, high-resolution evidence of livestock management strategies. Specifically, the research shed light on animal penning and feeding practises, revealing variable herbivorous regimes between species, the practise of seasonal movements, and the possible use of fodder as the main dietary regime of the animals stabled there. At the same time, the Baltarga case-study illustrates an indoor production unit that could reveal possible private control of some domestic animals in the Pyrenean Late Iron Age.
