Pg. 6 (fig. 2), 8 (fig. 4), 9, 24, pls. 2, 3, 4, 5. See also 1941 [abs.], GSA Bull., v. 52, no. 12, pt. 2, p. 1954. Tierra Loma shale member of Moreno formation. Is principally a brown shale. Thickness about 1,200 feet. Includes Mercy sandstone lentil (new) about 70 feet below the top. Underlies Marca shale member (new) of Moreno; overlies Dosados sand and shale member (new) of Moreno. Fossils (vertebrates, foraminifers). Age is Late Cretaceous. On the basis of this mapping it is concluded that Anderson and Pack (1915) show base of Moreno formation in [Ortegalito] Creek some 1,800 feet stratigraphically lower than their type Moreno in Moreno Gulch.
Type locality: Escarpado Canyon, Panoche Hills, 6 mi south of Moreno Gulch and 2 mi north of Panoche Creek, in secs. 7 and 8, T. 15 S., R. 12 E., [Chounet Ranch 7.5-min quadrangle], Fresno Co., southern CA. Named from Tierra Loma Schoolhouse [no longer exists] near E/4 corner sec. 9, T. 14 S., R. 12 E., [Tierra Loma School quadrangle, 1923 ed., scale 1:31,680].
