Researchers have identified numerous earthen animals rising above the coastal plains of Peru, a region renowned for the Nazca lines, the ruined city of Chan Chan, and other cultural treasures. Few animal effigy mounds had been found in South America until now. Shown here, University of Missouri anthropologist Robert Benfer stands near some of the smaller mounds. The mound in the distance is a small birdlike figure.
