Where: Kansas (39.6° N, 97.7° W: paleocoordinates 37.9° N, 60.2° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Graneros Formation, Cenomanian (100.5 - 93.9 Ma)

• "Probably of the Benton epoch, twenty feet below the Inoceramus bed" according to Cope. The area is mapped as the Graneros Shale and Greenhorn Limestone, which agrees with Cope's description (the Graneros Shale is part of the historical "Benton" shale).

• group of beds-level stratigraphic resolution

Environment/lithology: marine; gray claystone
