In Mexico city, 49 adult indigenous Mexican people were found in the remains of a pyramid in Tlateloco square, (destroyed by the Spanish). The pyramid was a mass grave, and many had already been found in it, buried haphazardly. However, these 49 were different because they were buried neatly, were all adult males, were tall, and some had bones that were previously broken. They are though to be some of the last Aztec warriors who fought the Spanish conquistadors (lead by Hernán Cotréz) during the conquest of Tlateloco square in 1521, which lasted for 76 days. Interestingly, these warriors not only buried neatly, but were also lying on their backs with their arm crossed (this is how Christians traditionally bury the dead). This indicates that the Christian Spanish did the burying. However, they burial also contains Aztec elements -- incense, animals, and copper necklaces, leading historians to hypothesize that the burials were ordered by the Spanish, but carried out by Aztecs.Overall, this discovery creates "more questions than it answers".
