Each unit in the measured sections was sampled for fauna and lithology. A fusulinid zonation was established for the Penn sylvanian of south-central Arizona and for the first time, conodonts were used to locate intraformational disconform- ities and stage boundaries within the Naco Formation. The study indicates that the formation in the area investigated is dominantly limestone, ranges from 483 feet to 1195 feet thick, and from Early or Middle Derryan (Atokan)
