Pg. 129. [Describes Foraminifera from Dornick Hills formation of Ardmore basin.] The fauna was obtained from rather pure shales exposed in sec. 30, T. 3 S., R. 2 E., Carter County, Oklahoma; shales which lie between Jolliff and Otterville limestones.

Dornick Hills formation. Bluish and tan shales interrupted by limestones and sandstones, with conspicuous limestone conglomerates south of Ardmore, [Carter County, south-central Oklahoma]. The pebbles in conglomerates consist chiefly of pre-Pennsylvanian limestones and chert such as now outcrop in Criner Hills. Basal member is Jolliff limestone member; top member is Pumpkin Creek limestone. Also includes (descending) Lester limestone, Bostwick limestone conglomerate, and Otterville limestone. Thickness 1,500 to 4,000 feet. Underlies Deese formation and overlies Springer formation.

Basal member is Joliff limestone member; top member is Pumpkin Creek limestone. Also includes (descending) Lester limestone, Bostwick limestone conglomerate, and Otterville limestone. Maximum observed thickness is about 4,000 feet at north edge of Love County. Thins northward to about 2,500 feet near town of Ardmore, and to less than 1,500 feet near Glenn Village. Underlies Deese formation and overlies Springer formation. Fossils (brachiopods, mollusks, etc.). Age is Pennsylvanian. Revised Water's Dornick Hills formation to include Goldston's [W.L. Goldston, Jr., 1922, AAPG Bull., v. 6, p. 8] Otterville and "Cup Coral" members of Glenn formation, and a little more. Report includes fossil list, geologic maps, columnar section.

Chart 6 (column 37). Dornick Hills group comprises (ascending) Jolliff, Otterville, Bostwick, Lester, and Frensley limestones, and Pumpkin Creek beds. Overlies Springer group; underlies Deese group. Morrow-Lampass series.

Pg. 137 (fig. 2), 138-143. [Dornick Hills] group redefined and subdivided into 3 formations (ascending): Golf Course (new), Lake Murray (new), and Big Branch. Golf Course formation includes the Primrose at base and the Otterville at top. Primrose sandstone and shale between the Primrose and Otterville are transferred from Springer group to Dornick Hills. Overlies Springer group; underlies Deese group. Age is Early and Middle Pennsylvanian (Morrow, Atoka, Des Moines).

Pg. A10-A11, A54, A56-A57 (fig. 5). Dornick Hills Group (rank raised). Divided into (ascending): Golf Course Formation and its Primrose Sandstone (lower and upper parts), Gene Autry, Jolliff, and Otterville Limestone Members (now reduced from formation rank); and Lake Murray Formation and its Bostwick Conglomerate and Griffin Members. Overlies rocks of Springer Group (now raised from formation rank). Age is Early and Middle Pennsylvanian (Morrowan and Atokan; Namurian and Westphalian of Europe).
