Archaeological excavations have been conducted in the Menzelinsky District of Tatarstan at the "Novobiksinteev Burial Ground." The burials of primitive people, according to radiocarbon analysis, date back to the second half of the fifth millennium BC, as reported by the Republic's Committee for the Protection of Cultural Heritage Sites. During the excavations, nine burials of Stone Age people were discovered. These contained stone arrowheads, as well as decorations made from deer and beaver teeth, fish teeth, marmot incisors, polished boar tusk plates, and round pendants made of Ural serpentinite. Archaeologists have established that similar finds have been encountered in burial sites located in the steppe zone of the European part of Russia. According to preliminary data, the burial ground is more than 15,000 years older than the Egyptian pyramids. The primitive people buried there did not yet know how to work metal. Tools were made from stone, bone, and wood. These people lived in small communities, engaging in fishing and hunting. At that time, the lakes and rivers were teeming with diverse fish species, and the forests were home to large animals such as deer, elk, and boar. This is evidenced by the artifacts found in the burials. Scientists particularly highlight two of the nine burials. The first is a double burial of a woman and a 4-5-year-old child placed between the mother's legs. The grave was covered with ochre and contained numerous ornaments. In the second burial lay the skeleton of an adult, which also contained a set of decorations, though fewer in number, including a carefully polished necklace made of boar tusks. In addition to the burials, archaeologists discovered votive complexes – small pits also abundantly sprinkled with ochre, in which offerings were placed. In one pit, 114 bone pendants were found, in another eight pendants of various shapes made from serpentinite, and in the third, a pendant and an arrowhead were discovered. Scientists have taken samples from the burials for radiocarbon analysis to help clarify their age. Anthropological and genomic analysis of the remains is also planned.
