Archaeologists scanning a Mexican pyramid for damage following September's devastating earthquake have uncovered traces of an ancient temple, BBC reports.
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.
Archaeologists say it would have measured 6m by 4m (20ft by 13ft). Among the temple's remains they also found an incense burner and ceramic shards.
The discovery was made when scientists from Mexico's National Institute of Anthropology and History (INAH) used a radar to check for structural damage to the Teopanzolco pyramid in Cuernavaca.
