Salem Point shale member of Grenola formation. The newly established Grenola formation is divided into following members (descending): Neva limestone, Salem Point shale, Burr limestone, Legion shale, and Sallyards limestone. The Salem Point member consists of gray shale, with a thin sandy-limy layer at Roca, Nebraska; of gray argillaceous shale with a thin nonfossiliferous sandy zone in southern Nebraska and northern and central Kansas; of gray calcareous and sandy shale thinning to past Hooser, Kansas, and Burbank, Oklahoma, becoming red shale at Fairfax, Ralston, and Pawnee, Oklahoma. It is less organic in origin and therefore less fossiliferous than Legion shale and Sallyards limestone. Thickness 3.5 to 10 feet. Report includes measured sections.
Type locality: the roadcuts at Salem Point, 1.5 mi northwest of Salem, Richardson Co., southeastern NE.
