Also known as BDM 2015-FPG-030

Where: Valley County, Montana (47.9° N, 107.3° W: paleocoordinates 54.7° N, 80.2° W)

• coordinate estimated from map

• small collection-level geographic resolution

When: Hell Creek Formation, Late/Upper Maastrichtian (70.6 - 66.0 Ma)

• BDM 2015-FPG-030 is a small microsite which occurs near the base of the Hell Creek Formation, ~5 m above the upper contact of what is probably the equivalent of the Hell Creek Basal Sandstone. This would place 2015-FPG-030 within the lower third of the Hell Creek Formation

• bed-level stratigraphic resolution

Environment/lithology: fluvial; mudstone

Size class: macrofossils
