INAH has uncovered a huge burial of over 60 mammoths and 15 humans at the General Felipe Ángeles International Airport north of Mexico City. Three exploration areas are being studied. The mammoth burials date to 12,000 years ago. The mammoths were stuck in the mud of what was then Lake Xaltocan. Humans may or may not have been involved in getting them there.
The farmers were buried with pots, bowls and clay figurines in domestic style burials. The human burials nearby are from a much later time period, 750-950 CE.
INAH has the report here (In Spanish);
