Where: Jefferson County, Nebraska (40.0° N, 97.2° W: paleocoordinates 38.1° N, 59.5° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Graneros Shale Formation, Middle Cenomanian (99.6 - 93.5 Ma)

• The exact stratigraphic horizon or range where the fossils were found is uncertain, but they all came from the typical dark-gray silty-clayey portion of the Graneros Shale below the X-bentonite, a stratigraphic level herein referred to as the "mid-Graneros."

• bed-level stratigraphic resolution

Environment/lithology: offshore; poorly lithified, gray, silty shale

Size class: macrofossils
