Medieval burials at Ryabchikov Klyuch-1, the Kansk-Rybinsk basin

Previously, burials at Ryabchikov Klyuch-1 on the Kan River near Kansk were dated to the Late Middle Ages (pre-Russian period) and attributed to autochthonous group. In 2015, two burials were discovered at the cemetery, with remains of an adolescent girl and a child. A comprehensive analysis of the burial rite and grave goods suggests that the burials date to the 12th century. Numerous archaeological and ethnographic parallels were found. Morphologically, the girl’s cranium reveals generally eastern traits, specifically those common in Western Siberian (Uralic and Ob-Irtysh) populations. The cranium was restored, and a graphical reconstruction of the face was made. Burial practices of the 17th-19th century Middle Kan populations are described. They were Ket-speaking Kotts, Turkic-speaking Karagas, and Samoyed-speaking Kamasins. The analysis of sources suggests that the buried people were likely ancestors of the Kotts.
