Siberian mummies adorned with copper

A fascinating discovery near the Arctic Circle:

The 34 shallow graves excavated by archeologists at Zeleniy Yar throw up many more questions than answers. But one thing seems clear: this remote spot, 29 km shy of the Arctic Circle, was a trading crossroads of some importance around one millennium ago.

The medieval necropolis include 11 bodies with shattered or missing skulls, and smashed skeletons. Five mummies were found to be shrouded in copper, while also elaborately covered in reindeer, beaver, wolverine or bear fur. Among the graves is just one female, a child, her face masked by copper plates. There are no adult women.

Nearby were found three copper masked infant mummies - all males. They were bound in four or five copper hoops, several centimeters wide.

Similarly, a red-haired man was found, protected from chest to foot by copper plating. In his resting place, was an iron hatchet, furs, and a head buckle made of bronze depicting a bear...

Artifacts included bronze bowls originating in Persia, some 3,700 miles to the south-west, dating from the tenth or eleventh centuries. One of the burials dates to 1282, according to a study of tree rings, while others are believed to be older. ..

Unlike other burial sites in Siberia, for example in the permafrost of the Altai Mountains, or those of the Egyptian pharaohs, the purpose did not seem to be to mummify the remains, hence the claim that their preservation until modern times was an accident.

The soil in this spot is sandy and not permanently frozen.  A combination of the use of copper, which prevented oxidation, and a sinking of the temperature in the 14th century, is behind the good condition of the remains today.
