Shifts in the Genetic Landscape of the Western Eurasian Steppe Associated with the Beginning and End of the Scythian Dominance Highlights d 31 new ancient genomes help compare the Scythians to preand postdating cultures d Scythian dominance brought along an increase of eastern ancestry across the steppe d Results imply some demic diffusion in the spread of the Scythian culture d Genetic makeup agrees with the Gothic source of post-Scythian Chernyakhiv culture

The paper presents the outcome of the magnetic survey at the settlement and cemetery of the production center of the 3rd—5th centuries, Komariv (Khotyn district, Chernivtsi region), which is located on the right bank of the Dniester. The settlement has about seventy anomalies that may have an archaeological origin. The archaeological study of individual anomalies has confirmed, as expected, the reliability of geophysical interpretation of thermal structures (kilns, furnaces) and living and production dugouts deepened into the loess parent rock. Magnetic imaging at the cemetery showed about eight tens of local anomalies with an intensity of 1.5—4.5 nT. Excavations of some anomalies revealed the Early Iron Age dugout and two Late Roman graves. However, the other two excavated graves did not cause disturbance of magnetic field. Laboratory measurements of magnetic susceptibility, natural remanent magnetization and other concentration-dependent and grain-size-dependent parameters of the ferromagnetic phase, as well as magnetic mineralogy examination have shown that grave pits, which appeared on a magnetic map, are refilled almost exclusively with humus soil material. Magnetic modeling proved graves can create measured anomalies if their magnetization is equal to the magnetization of the humus horizon of the soil. Thus, these grave pits were left open and gradually refilled with moist soil material. In particular, conditions have been created for the formation of detrital remanence. When restoring the spatial structure of Komariv sites based on magnetic prospecting results, it is necessary to take into account probable multilayered structure of monuments, geomorphological features of the area, which can be misinterpreted as archeological objects, and the fact that important examples of ancient architecture constructed of non-magnetic materials and grave pits refilled immediately after digging will be absent on magnetic maps.

An archaeological map of Buzovitsya-1 Roman time site was obtained based on a combination of geophysical and remote sensing results. The KH-9 Hexagon image reveals Roman structures.
