Summary:
Sallyards limestone 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 Sallyards member is fossiliferous massive earthy limestone at Roca, Nebraska; in southern Nebraska and northern Kansas it is shaly, fossiliferous, and limy; in Oklahoma it is impure limestone grading into sandstone. Its numerous pelecypods at most points indicate that it is a near-shore marine deposit. Where there is a comprehensive fauna (as at Sallyards, Grenola, and Hooser, Kansas) it is more typically marine. Thickness 6 inches to 3.5 feet. It rests on Roca shale. Report includes measured sections.
Type locality: south bank of ravine 1 mi northeast of Sallyards, Greenwood Co., KS. Named from town of Sallyards.
