Archaeologists working along the Irtysh River near Omsk have uncovered this amazing suit of bone armor. It has not yet been dated, but based on where it was found it was probably made in the Bronze Age, perhaps as old as 3500 to 3900 years ago.
The armor does not seem to be local; it more closely resembles objects from the Samus-Seyminskaya culture of the Altai Mountains, about 1,000 km to the south east. So it may have been a gift, or spoils of war. It was found in isolation, not in a grave, so it may have been buried or thrown into the river as a sacrifice. The bone seems to be deer or elk.
Reconstruction. I have never seen anything like this, and when I did a search for "bone armor", the only things that came up were video games and this Siberian find.
