[1][2][3][4][5][6][7] Tsagaan Agui is located in Bayankhongor province (aimaq) in the southern foothills of the Gobi Altay Mountains at 44º 42´ 43.3” N, 101 º 10´13.4” E, about 40 km northeast of the Bayan Lig county (suum) administrative center, southwest of the Zuun Bogd Uul (Baga Bogd Uul) mountain range.
[2] JMRAAE reinitiated excavations at Tsagaan Agui in 2021 with support from the Leakey Foundation and the University of Arizona's Je Tsongkhapa Endowment for Central and Inner Asian Archaeology.
[2] Based on the analysis of artifacts from the lowermost horizons at Tsagaan Agui Cave, it is suggested that a Levallois-Acheulean like industry existed in Mongolia as early as 500-400 thousand years ago.
[2][12] Pollen of broad-leaved species such as elm, hornbeam, maple, and lime and grains of grasses including members of the Moraceae, Lonicera, and Juglans families were detected.
[2] A relatively humid environment was reconstructed in the bottom of the sediment column, therefore animal remains were only recovered from the upper units, especially from Strata 1–5 in the Main Chamber.
Mammals associated with open steppes and montane niches, including kulan, arğalı, Siberian goat and dzeren (all currently present in Mongolia) dominated the faunal assemblage.
