Pg. 133-145. Waldrip limestone member of Waldrip formation (3rd from top of 7 formations in Cisco division). At Cisco the limestone is a dense crystalline and dark-gray fossiliferous bed, but in north part of Shackelford County west of Breckenridge it changes to sandstone and disappears. Overlies coal bed which forms a conspicuous scarp throughout its outcrop. In places where the coal does not outcrop the Waldrip limestone can be identified by the large numbers of large crinoids on its surface and the characteristic fossils from the shale just below. Underlies Pueblo formation. Age is Pennsylvanian. Report area in Brazos River Valley, north-central Texas.
Type locality not designated. Derivation of name not stated, but probably named from Waldrip, McCulloch Co., TX.
[GNC remark (ca. 1938, US geologic names lexicon, USGS Bull. 896, p. 2264): In 1922 Plummer and R.C. Moore replaced this name with Saddle Creek limestone member, finding it to be same as Drake's older name Saddle Creek bed.]

"Waldrip Bed" of Drake (1893) not used--these rocks assigned to newly named Harpersville formation of Cisco Group (revised) in the Colorado River Valley, north-central TX on Bend arch. In the Colorado River Valley Harpersville consists of a persistent dark-gray limestone at top--the Saddle Creek [limestone member]--and beneath it a series of blue clays, carbonaceous and ferruginous shales, containing lenses of sandstone and a few conglomerate beds, and three limestone beds, buff, yellow, and brown in color. The three limestone beds were designated Waldrip Beds 1, 2, and 3 by Drake (1893). [The Saddle Creek limestone [member] is probably the same as "Waldrip limestone" [member] of Waldrip formation as described by Plummer, 1919--this is not stated, however.] The uppermost of these three limestone layers contains many FUSULINA and, more rarely, other fossils, so that it is quite easily recognized and possibly is to be correlated with the newly named Belknap limestone [member, of Harpersville] of the Brazos River Valley. Stratigraphic chart, measured sections. Of Pennsylvanian age.
