A new altar and stele have been found at Chalcatzingo in Morelos
dating back to the Olmec period, between 800-500 BCE. Almost a year
ago, a striking Olmec style 3 cats bas relief was found at the site
from the same time period. (See URL below);

A multiple burial was also found with ceramic offerings. 2 individuals
were found in a context which suggests re-burial, perhaps to dedicate
the new structure. Obsidian cores were found at a 3rd spot in a
residential unit at the same Olmec time period. Obsidian is rare in
this area so the cores must have been brought there. Lots of obsidian
flakes are also there, suggesting this was an obsidian workshop.

INAH has the report here (in Spanish);
