The article presents the materials of archaeological research carried out in the field season of 2020 in the Aksu district, Almaty region of the Republic of Kazakhstan, by the employees of the Archaeological Expedition LLP. The works were carried out on mounds 33 and 34 of the Tausamaly burial ground. The burial ground consists of more than 80 embankments and occupies the entire alluvial cone of the Aksu River. The planigraphy of the burial ground, the construction of embankments, specific non-burial structures and the presence of a Pazyryk appearance on the northern outskirts of the monument (emergency excavations in 2019) made it possible to attribute the Tausamals to the Late Pazyryk type. As a result of new research, burials in stone boxes, on the back, with their heads in the northwestern sector, were revealed under the mounds of the mounds. Accompanying inventory and funeral rites allow the monuments to be dated to the end of the 1st millennium BC. Analogies are found in a small group of burials in stone and wooden boxes on the territory of Zhetysu. A similar type is found scattered among the mounds of the Sako-Usun time in the burial grounds of Kadyrbai III, at the Chilik tobacco state farm, Kzyl-Espe and others dating from the 4th century. BC. until the IV century. AD Newly examined burials in boxes supplement the available data, and their finding in a burial ground with pronounced Pazyryk features makes it possible to establish links for the entire group with the burial traditions of the nomads of Sayan-Altai and Mongolia at the end of the 1st millennium BC. and the turn of the era.
