The human environment of the Xiongnu Ivolga Fortress (West Trans-Baikal area, Russia): Initial data

摘要

This article deals with the initial data coming from the Ivolga Fortress archaeological site located in the Trans-Baikal area. Multidisciplinary investigations were performed, including palynological and archaeozoological studies. Palynological data reflects the palaeovegetation of the region and shows the abundance of forested landscapes in the past. The fauna was made of molluscs (7 taxa), fishes (14 taxa), amphibians (3 taxa), reptiles (1 taxon), and wild mammals (18 taxa). The species composition and environmental data show the mosaic character of landscapes surrounding the ancient settlement: taiga and forest, steppe and forest-steppe biotopes, as well as meadows in the Selenga valley with the prevalence of open steppe spaces. In the era of the Xiongnu Empire 209 BC - 48 AD (Kradin, 2001) the climate was less arid than it is now.
