Sungir (Сунгирь, sometimes spelled Sunghir) is an Upper Paleolithic archaeological site in Russia and one of the earliest records of modern Homo sapiens in Eurasia. It is situated about two hundred kilometres east of Moscow, on the outskirts of Vladimir, near the Klyazma River. It is dated by calibrated carbon analysis to between 32,050 and 28,550 BC. Additional pollen finds suggest the relative warm spell of the "Greenland interstadial (GI) 5" between the 30,500 and 30,000 BCE as most probable dates. The settlement area was found to have four burials: the remains of an older man and two adolescent children are particularly well-preserved, and the nature of the rich and extensive burial goods suggests they belonged to the same class. In addition, a skull and two fragments of human femur were also found at the settlement area, and two human skeletons outside the settlement area without cultural remains. This site was discovered in 1955, in the course of local digging from clay pits. Some 4500 square meters were excavated in sixteen field seasons between 1957 and 1977 (Bader 1965; 1967; 1978; 1998). Archeology teams from the Geological Institute of the Russian Academy of Science (R.A.S.), University of Groningen, Oxford University, and the University of Arizona in the United States have all worked on the excavations and related studies to review the findings from the site. They determined that the cultural layer was located in what is called Bryansk soil, related to the period (thirty-two to twenty-four millennia ago) of the corresponding interstadial of the Valdai Ice age of the Late Pleistocene. Evidence of only surface dwellings on the site led the team to conclude it was likely used seasonally. Graves 1 and 2 at Sungir are described as "the most spectacular" among European Gravettian burials. The adult male was buried in what is called Grave 1 and the two adolescent children in Grave 2, placed head-to-head, together with an adult femur filled with red ochre.
