TEHRAN - Russian archaeologists have unearthed a burial site expected to date from the Stone Age during an excavation recently completed in Tatarstan.

The burial ground was created from 4500 to 4000 BC, TV BRICS reported.

Scientists during excavations revealed nine burials of primitive people. There were found stone arrowheads, and jewellery made of animal tusks and stone.

Researchers believe that the burials may be older than the Egyptian pyramids by more than 1,500 years. It probably belongs to primitive people who did not yet know how to work metal, and made tools from stone, bone and wood.

Among the most striking burials, archaeologists have identified two. The first is a woman with a five-year-old child between her legs. In addition, scientists found the skeleton of an adult individual whose grave contains a necklace made of polished tusks of the same animal.

In addition to burials, sacrificial complexes were recorded at the necropolis site. They are pits sprinkled with ochre, in which offerings were placed. There the researchers cleared 114 bone pendants, serpentinite jewellery and an arrowhead.
