The recent discovery of 800-year-old pyramid ruins reveals the founding of the area that is now Mexico City to be around a couple hundred years older than previously estimated:

The ancient city, once a major religious and political center for the Aztecs, was thought to be founded in 1325 after the discovery of another pyramid at the site 15 years ago.

“We have found the stairs of this, much older pyramid. The (Aztec) timeline is going to need to be revised,” archeologist Patricia Ledesma said.

The newly found pyramid is believed to have been built in 1100 or 1200. The ruin is about 36 feet (11 meters) high, and more studies are still needed for prove the pyramid’s size and age.

“What we hope to find soon should tell us much more about the society of Tlatelolco,” said Ledesma.

That’s pretty old. Old like, say… Oh, the age Walter Mercado’s original parts would have been? Oh Jesus, shut up. We’re only joshing.
