Archaeologists in Siberia have excavated the burial of a man who went into the ground wearing a cloak made of bird beaks. A section of the cloak is preserved below his left hand in this photo. Mor was piled into a pillow behind his head.
Detail of the beaks; analysis is not complete but they look like herons or cranes. This is one of the most shamanistic things I have ever seen. Via The History Blog.
