What's in a Hearth? Preliminary Findings from the Margal Hunter-Gatherer Habitation in the Eastern Mongolian Gobi Desert

abstract: Today's image of people inhabiting the vast steppe landscapes of Mongolia is inseparably linked to mobile animal herding. Indeed, archaeologists have confirmed that human-animal communities comprised of human herders and domestic livestock roamed across Mongolia's grassland environment and utilized semi-arid to arid regions such as the Gobi steppe desert for thousands of years. However, it is much rarer to catch a glimpse of the time before the advent of pastoralism in this part of the world. During the Neolithic (ca. 6000–1800 b.c.), the Gobi was much less of a desert than it is today. Sparsely scattered archaeological sites testify to the presence of hunter-gatherer groups that successfully exploited rich wetland environments. As a result of the pedestrian survey carried out by the Dornod Mongol Survey in the greater region of Delgerkhaan Uul, we discovered in situ remains of a Neolithic habitation site. Excavations at the Margal site uncovered a stratified hearth and a lithic assemblage embedded in a habitation layer and accompanied by a few faunal bone fragments. Our finds correspond with the Oasis 2 stage (ca. 6000–3000 b.c.) of the scheme established by Janz and colleagues dividing the Mongolian Neolithic into phases based on habitation, as well as subsistence patterns and technology. However, some typical Oasis 2 markers such as pottery and grinding tools are missing from the small assemblage uncovered from test excavations in 2017 and 2018. Margal likely belonged to a regional network of extended hunter-gatherer occupation relying on wild plant and faunal resources. The site represents the first of its kind in the region and has potential to shed light on hunter-gatherer subsistence and habitation decisions. In concert with adjacent archaeological surface scatters and contextualized in the supraregional network of hunter-gatherer habitation, it will contribute to refining current models of lifeways and transformations in Mongolian prehistory.
