The pits were about 1.7 metres deep and 25 metres in diameter.
However, INAH's discovery of the human-built traps could mean such hunts were planned.
Archeologists believe the site, in the San Antonio Xahuento district, may be one of a series nearby that reduced the margin of error for hunters.
Experts think that groups of between 20 and 30 hunters used torches and branches to separate some mammoths from their herd and direct them into the traps.
It was previously thought that early humans could only killed mammoths that had been trapped or hurt.
It challenges the long-standing belief that humans only attacked mammoths when the opportunity presented itself, such as when a mammoth became trapped in a swamp, Sanchez Nava said in a news release.
Not only were the animals eaten, but they were honoured after the hunts. In that case, workers digging to install drainage pipe uncovered mammoth remains.
The traps consist of two pits that were used by hunters to corner and kill the huge animals.
After finally achieving their goal, they arranged its bones in a symbolic formation.
The remains of species of horse and camel that disappeared from the Americas were also discovered at the site. Researchers also believe there may be more such traps in the area.
The pits were found while space was being cleared for a garbage dump in Tultepec, north of Mexico City.
