Petroglyphs of the Early Iron Age make up a large group of Tamgaly petroglyphs and differ in style, quality and content. they were created by different populations (Saki, Yuezhi, Usuni, Xiongnu, Syanbi), which replaced each other in Semirechye in view of numerous movements. In view of the rare opportunity to determine the exact age and cultural identity, the images of animals (mainly goats) are highly schematized and rather crude in execution.
