AREQUIPA, PERU—Peru This Week reports that a team of archaeologists from Poland’s University of Wroclaw and Peru’s Universidad Católica de Santa Maria discovered tombs from the Tiwanaku culture near the coastline in Peru’s Tambo Valley. Looters had been to the site, but the scientists were able to recover human remains and artifacts. The tombs had been constructed between 600 and 800 A.D. The researchers do not expect to find a Tiwanaku settlement in the area.
