A new Early Carboniferous nautilid from the Caney Formation of Oklahoma, Central North America

The Caney Formation, named and defined by Taff (1901), comprises a relatively thin (approximately 115 m thick in the type section) marine sedimentary unit consisting mostly of shale with limestone concretions. The formation is divided into the Ahloso, Delaware Creek, Sand Branch, and Rhoda Creek Members in ascending order (Elias, 1956; Elias and Branson, 1959, and others). We describe below a new trigonoceratid nautilid species, Epistroboceras caneyense, recovered from limestone concretions in the dark gray shale of the Sand Branch Member at the type section for this member. The material examined was collected at an outcrop in the stream bed of Sandy Branch Creek, approximately 1.6 km downstream from the junction of this stream and Highway 48 south of the town of Wapanucka, Johnston Co., Oklahoma. The locality is identical to loc. 2082 (Girty, 1909) and loc. M-15 (Mapes, 1979). Ammonoids, including Cravenoceras richardsonianum and Eumorphoceras bisulcatum, from this locality indicate a middle Chesterian (late Early Carboniferous) age in Gordon’s (1964) biostratigraphic scheme.
