Aztec exhibition opens as archaeologists seek royal tomb

Archaeologists working on an excavation in downtown Mexico City think they are on the brink of discovering the first Aztec royal tomb ever found. Meanwhile, objects from the dig are on display at "Moctezuma II: Times and Destiny of a Ruler" at the Templo Mayor Museum.

The showpiece of the exhibition is an enormous stone slab found in 2006, bearing the image of the goddess Tlatecuhtli. The carving was discovered with offerings of jewelry and sacrificed animals.
