Archaeologists have uncovered ten ancient burial mounds, known as kurgans, in Kazakhstan's Ulytau region, with some displaying distinctive "mustaches." These kurgans, which likely date back to the Early and Medieval Nomadic periods, were found by a team led by Zhanbolat Utubaev from the Margulan Institute of Archaeology. Three of the kurgans are unique in that they feature two ridges of stones that extend outward, giving them the appearance of mustaches, said Zhanbolat Utubaev, an archaeologist at the Margulan Institute of Archaeology in an email response to Live Science. This distinctive feature has led to their classification as "mustached kurgans," a type of burial mound that is fairly common in central Kazakhstan. More than 400 such structures have been documented across the region. The sizes of these mounds vary significantly, ranging from about 10 to 50 feet (3 to 15 meters) in diameter, Utubaev explained.
