Summary:

Pg. 133-145. Pueblo formation of Cisco [group]. Bounded at top by Pueblo limestone [Camp Colorado limestone], which is yellow, fossiliferous, and impure. Near Red Bed line in Stephens County, central northern Texas, it changes to sand and loses its identity, but just below its horizon is a thin limestone abundant in MYALINA fossils [pelecypods], which characterize this bed. The members of this formation are so variable that no one section is typical. Underlies Moran formation and overlies Waldrip formation [now (ca. 1938) replaced by Harpersville formation]. [Age is Pennsylvanian.]
[Named from exposures along valley of Battle Creek at Pueblo, Callahan Co., Brazos River Valley, central northern TX.]

Summary:

Pg. 66 (fig. 1), 91, 93. Pueblo group. Rank raised to group and expanded below to redefined Permian-Pennsylvanian boundary (Wolfcamp-Cisco) which is placed at disconformity in Harpersville formation above Waldrip-Newcastle coal zone about 40 to 150 feet below Saddle Creek limestone. As redefined includes (ascending) Saddle Creek, Stockwether, and Camp Colorado formations. Underlies Moran group; overlies Thrifty group (redefined).

Summary:

Pg. 276-270. Pueblo formation, in Brazos River Valley, comprises (ascending) Waldrip shale, Saddle Creek limestone, Camp Creek shale, Stockwether limestone, Salt Creek Bend shale, and Camp Colorado shale members. Thickness 275 to 400 feet. Overlies Chaffin limestone member of Thrifty formation; underlies Watts Creek shale member of Moran formation. Locally, Chaffin and underlying shale members of Thrifty are absent and Pueblo rests on rocks as old as Breckenridge member of Thrifty. Boundary between Pueblo and Moran not mapped north of Elm Creek (east-central Throckmorton and west-central Young Counties, northern central Texas); boundary difficult to discern because of probable absence of Camp Colorado limestone. [Age is Early Permian (Wolfcamp).]
