Oxtotitlán

Oxtotitlán Mural 1

Oxtotitlán is the name of a natural rock shelter and archaeological site in Chilapa de Álvarez, Mexican state of Guerrero that contains murals linked to the Olmec motifs and iconography. Along with the nearby Juxtlahuaca cave, the Oxtotitlán rock paintings represent the "earliest sophisticated painted art known in Mesoamerica", thus far. Unlike Juxtlahuaca, however, the Oxtotitlán paintings are not deep in a cave system but rather occupy two shallow grottos on a cliff face.
