4,000-year-old Shaman's stones discovered near Boquete, Panama

Archaeologists working at the Smithsonian Tropical Research Institute in Panama have discovered a cluster of 12 unusual stones in the back of a small, prehistoric rock-shelter near the town of Boquete. The cache represents the earliest material evidence of shamanistic practice in lower Central America.
Ruth Dickau, Leverhulme Post-doctoral Fellow at the University of Exeter, unearthed the cache of stones in the Casita de Piedra rock-shelter in 2007. A piece of charcoal found directly underneath the cache was radiocarbon dated to 4,800 years ago. A second fragment of charcoal in a level above the cache was dated to 4,000 years ago.
