2,300-Year-Old Plush Bird from the Altai Mountains of Siberia (c.400-300 BCE): this artifact was crafted with a felt body and reindeer-fur stuffing, all of which remains intact

This stuffed bird was sealed in the frozen barrows of Pazyryk, Siberia, for more than two millennia, where a unique microclimate enabled it to be preserved. The permafrost ice lense formation that sits just beneath the barrows provides an insulating layer, preventing the soil from heating during the summer and allowing it to quickly freeze during the winter; these conditions produce a separate microclimate within the stone walls of the barrows themselves, thereby aiding in preservation.

This is just one of the many well-preserved artifacts that have been found at Pazyryk. These artifacts are attributed to the Scythian/Altaic cultures.
