Also known as UCMP locality V80092; MOR HC-530, Doldrums

Where: Garfield County, Montana (47.7° N, 106.4° W: paleocoordinates 54.3° N, 79.4° W)

• coordinate estimated from map

• small collection-level geographic resolution

When: Hell Creek Formation, Lancian (70.6 - 66.0 Ma)

• The locality is a small shallow wash with extensive exposures of a bone-rich basal lag of the Ten Meter Sand (Hartman et al., 2014; Fowler, 2016). The Ten Meter Sand occurs ~10 m below the contact with the overlying Fort Union Formation (which is visible in adjacent cliffs ~100 m to the east), hence V80092/HC-530 is located in the upper part of the upper third of the Hell Creek Formation

• bed-level stratigraphic resolution

Environment/lithology: coarse channel fill; sandstone

Size classes: macrofossils, mesofossils

Collected in 1980; reposited in the UCMP
