Pg. 421, 428. Paint Rock bed in Albany division [Wichita group]. Largely dark-colored shaly, slightly carbonaceous limestone interstratified with thin layers of carbonaceous argillaceous lime shale. Fossilfierous. Thickness 150 feet. Top member of Albany [Wichita] division. Age is possibly Permian.
Exposures of the typical rock along Mustang Creek, from its mouth to within 1.5 mi of Norwood, Concho Co., Colorado River region, central TX. [Named from town of Paint Rock, Concho Co., Colorado River region, central TX.]

Pg. 8, 9, 30-41, map. Paintrock formation (redefined). As here considered begins with No. 128 of general section and extends to top of No. 141. This leaves a thickness of 81 feet for the formation; Drake's thickness was 150 feet. He began Paintrock beds much lower than base here used, judging from his map, showing lower limit along Pony Creek. [These lower rocks must have been transferred to underlying Talpa limestone.] The rocks of this formation are more evenly bedded and somewhat more resistant than those of the two underlying formations [Talpa and Grape Creek]. The fauna is more sparse and less varied. Upper limit is rather hard to determine before fauna of whole section is worked out, since lithologic changes are not sharp at any point. Underlies Lueders formation, which contains larger proportion of shale and nearly impure limestones. All included in Wichita stage.

Pg. 197-198. [As Clyde formation was defined in this report it did not include Paint Rock bed of Drake, but the Paint Rock appears to be included in Wichita group, for authors state (p. 198, footnote) "the Talpa [top member of their Clyde formation] and Paint Rock beds are two formations sufficiently closely related to go in one and the same group."]

Sheet 2. Paint Rock limestone; Paint Rock beds; Paint Rock formation of previous workers. Type "Paint Rock" in Concho County, central Texas, has been traced into type exposure of Talpa limestone; "Paint Rock" is a synonym for Talpa limestone and preference in nomenclature is given latter term.
