They were killed by having their chests cut open, many with their hearts removed.
Evidence suggests the sacrifice was to do with a "climactic event" that could have hit the "economic, political and ideological stability of one of the most powerful states in the New World".
The human remains started to be dug up six years ago, after residents near the Huanchaquito-Las Llamas site noticed bones eroding out of the roadside.
An emergency excavation was ordered and archaeologists discovered the bodies over multiple digs of the 700 square metre site.
