The Tecomazuchil Formation is a geologic formation in Oaxaca, Mexico. It is made up of "a basal conglomerate 135 m thick and predominantly composed of quartz and metamorphic rock fragments, overlain by about 600 m of interbedded tan to red conglomerates, sandstones, and siltstones. The Tecomazuchil Formation overlies unconformably the Acatlán Complex and has been assigned a Middle Jurassic age, though it could represent at least part of the Oxfordian."[2] Fossil Bennettitales have been found in the formation.[3]
