The article presents an analysis of the burial rite and chronology of the Gumarovo cemetery, located on the border of the steppe and mountain-steppe zones of the Southern Urals, at the southern tip of the almost completely forested low plateau Zilair (Russia, Orenburg oblast, right bank of the Sakmara River). The cemetery consists of 5 stone kurgans, explored in 1979–1980 by an expedition led by R.B. Ismagilov. A burial of Early Scythian time was revealed in one of the kurgans (the so-called “Bolshoy Gumarovskiy”, “Big Gumarovo”), and immediately became widely known among researchers. The cemetery itself belongs to a later time, also known as “Sauromatian” time. Based on the chronological indicators and simultaneous occurrence of accompanying inventory categories, it is determined that the cemetery dates back to the end of the 5th – beginning of the 4th centuries BC and existed for a very short time. The burial rite features of the Gumarovo kurgans (stone mounds, wide oval graves, sloping walls, circular chamber graves, heads of the deceased oriented to the west and the east) indicate that it belongs to a special “Mugodzharian” group of nomads from the Southern Urals steppes eastern part. The origin of this group of nomads is associated with the migration of the Northern and Central Kazakhstan nomads to the steppes of the Orsk-Ilek interfluve, i.e. to the west of the Mugodzhar ridge; with their long-lasting interaction with the local population of the Sauromatian (proved by Blumenfeld and East Aral complexes) and Early Sarmatian time; as well as assimilating part of the Early Saka appearance population, which occupied the steppes of the Southern Trans-Urals in the 7th – 6th centuries BC. It is shown that it is the “Mugodzharian” features that make the kurgans in the eastern part of the Southern Urals steppes significantly specific.
