Where: Cedar County, Nebraska (42.7° N, 97.0° W: paleocoordinates 42.8° N, 60.8° W)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Blue Hill Member (Carlile Shale Formation), Middle Turonian (93.5 - 89.3 Ma)
• Located at least 25 m below the contact between the Blue Hill Shale Member and Fort Hays Member (i.e., within the bottom half of the Blue Hill Shale). An ammonite Collignoniceras percarinatum (Hall and Meek, 1856) is reported from “the middle part of the Carlile Shale” in Dixon County (Kennedy et al., 2001, fig. 48), that dates the Blue Hill Shale (Fig. 1A) to the Middle Turonian.
• group of beds-level stratigraphic resolution
Environment/lithology: offshore; poorly lithified, nodular, phosphatic shale
Size class: macrofossils
Collected by J.I. Kirkland; reposited in the UNSM
Collection methods: surface (in situ)
