Archaeologists have unearthed remains of 42 children and 74 llamas and related animals that were sacrificed some 800 years ago in the fishing town of Huanchaquito, Peru.

The remains were from a massive sacrifice that formed part of a religious ceremony of the pre-Inca Chimu culture for the fertility of the ocean and the land, Reuters reported.

Oscar Gabriel Prieto, chief archaeologist on the dig, said the findings represent the largest discovery of sacrifices from the Chimu culture.

Below are the pictures of the mysterious remains.
