Abstract
The Jemez Springs area of north-central New Mexico contains rocks ranging in age from Precambrian to Recent. Resting on Precambrian granite are 15 to 20 feet of Mississippian limestone and shale belonging to the Arroyo Peñasco formation of probable Meramecian age. The marine fauna is restricted to Pennsylvanian rocks. In this study. 64 species representing 40 genera were recognized, and the majority are illustrated and systematically described. Fossil evidence indicates a Lampasan (Atokan) age for the Sandia formation and a Desmoinesian, Missourian, and Virgilian age for the Madera limestone. Correlation was based primarily on the predominant and well-preserved brachiopod fauna. Fusulinids offered supplemental evidence for age determinations.
Collections from Permian rocks include one species of reptile and 6 species of plants.
An index map, correlation chart, and 8 fossil plates accompany the report.
