Macro- and microbotanical remains recovered from post-Teotihuacan occupations in quarry tunnels east of the Sun Pyramid, Teotihuacan, contribute to understanding lifeways in the surrounding valley after the partial abandonment of the city. Plant remains associated with domestic and ritual contexts from the excavations directed by Linda Manzanilla (1993–1996) are relevant to subsistence questions, aspects of surrounding vegetation, landscape exploitation, and the possibility of less-intensive agricultural production during the Epiclassic and Early Postclassic occupations.
