Archaeologists scanning a Mexican pyramid for damage following September's devastating earthquake have uncovered traces of an ancient temple.
The temple is nestled inside the Teopanzolco pyramid in Morelos state, 70km (43 miles) south of Mexico City. It is thought to date back to 1150 and to belong to the Tlahuica culture, one of the Aztec peoples living in central Mexico. The structure is dedicated to Tláloc, the Aztec rain god.
