In both locations, it is possible to discern the process of megalithic construction, availability of raw material, and the conditions of labour. It is known from the present state of stone quarries that the length of the upright stone blank is usually situated on an east-west axis. A large amount of stone was separated from the capstone blank and other stones at the megalithic burial sites. Cracks on megalithic stones indicate at which points excess stone is removed. In the process of separation, stones crack along the long axis.
Cracks also appear on the short axis.
It seems likely that the process of separation, the transportation of stone to the megalith site, and the construction of the megalithic burial structure were achieved by planning. It was found that there are six possible ways to strike the upright stone to produce different intensities of cracking for the removal of the stone from the quarry. During the 8th to 3rd centuries BC, northern Eurasia was occupied by nomads from the northern shore of the Black Sea to the Ordos region of northern China. Their material culture is represented by the 'Three Scythian factors' characterized by horse trappings, arms, and stylistic animal motifs. The material culture from the Black Sea to Ordos was improperly called 'the Scythian Culture' until recently, because the proper sense of the word 'Scythian' originally implies those who left the material culture around the northern shore of the Black Sea.
