Archeologist Pieter Van Dalen Luna, who is in charge of the Cajamarquilla project, called the find “peculiar and unique”.
“The mummy would have been buried sometime between 800 and 1200 AD,” he said – meaning it would be at least 800 years old.
On one side of the mummy, experts found the skeleton of an Andean guinea pig and what appears to be a dog, according to the researchers at the University of San Marcos.
Traces of corn and other vegetables were found in the burial chamber.
