This is a very important update for BitDrifter's clip about Aztec finds. The CNN story, which was the source of the clip only mentioned about an altar belonged to 16th century Aztec empire.

But, on this AP story, it appears that the Aztec findings was relatively less important and the "big thing" of the archaeologists found was a glyphed calendar entry, believed to be carved around 700 BCE! If proved, this would make it an outstanding discovery in Mesoamerica archaeology, because it outdates the earliest samples by hundreds of years!

And this is perhaps (at least) as important as the calendar discovery itself:

The lunar calendar has frequently been associated with female figures. The site where the stone was found was also a sacred area and burial ground occupied by the graves of 14 females, whose pottery offerings depicted women.

'This suggest that women played very important roles, not only as priestesses, but politically as well,' Ahuja said.

Luciano Cedillo, director of Mexico's National Institute of Anthropology and History _ which employs Ahuja _ called the find 'important and surprising.'
