Pg. F4-F5, F6-F7 (fig. 2). Los Moyos Limestone of Madera Group. Consists of (ascending): (1) basal few feet of gradational beds, from the dark-colored calcareous shale and shaly limestone of the underlying Sandia formation; (2) 80 to 100 feet of cliff-forming olive- to medium-gray calcarenite; (3) cliff-forming cherty gray limestone, thin beds of dark-colored shale, and minor grayish-orange to orange siltstone, sandstone, and conglomerate; (4) top is cliff-forming calcarenite that in most places contain nodular masses of black chert. Thickness about 600 feet. Underlies Wild Cow Formation of Madera Group. Fossils (fusulinids). Age is late Middle to early Late Pennsylvanian (Desmoinesian to earliest Missourian).
Type section [= type section of Wild Cow Formation]: on west side of Priest Canyon in an east-draining ravine that cuts through a hogback, in sec. 7, T. 3 N., R. 5 E., [approx.

Pg. 6+, pls. Los Moyos Limestone of Madera Group. Consists of cliff-forming, massive, cherty, gray limestone, with subordinate amounts of dark-colored calcareous shale, sandstone, and minor conglomerate. Thickness averages 600 feet in the Manzano Mountains. Is basal formation of Madera Group. Gradationally overlies Sandia Formation; for mapping purposes, contact placed at base of lowest cherty, ledge- to cliff-forming, rusty orange-weathering limestone. Formation lies mostly within the fusulinid Foraminifera zone of BEEDEINA (assemblage subzones B. SULPHURENSIS, B. ROCKYMONTANA, B. NOVAMEXICANA, and B. INSOLITA, descending), indicating Desmoinesian. Upper 10 feet of formation, at a single locality, yielded fusulinid EOWAERINGELLA cf. E. JOYITAENSIS Stewart, 1968 (Cushman Foundation Foram. Research Spec. Pub., no. 10), of apparent earliest Missourian time. [Age of formation is considered late Middle Pennsylvanian (Desmoinesian).]
