DMNH 7066 (Paleocene of the United States)

Also known as Corral Bluffs

Where: El Paso County, Colorado (38.9° N, 104.5° W: paleocoordinates 45.1° N, 82.5° W)

• coordinate estimated from map

• small collection-level geographic resolution

When: Puercan 2 mammal zone, Denver Formation, Puercan (66.0 - 63.3 Ma)

• There are 11 different lithologic sections. It is not mentioned from which section comes each locality. The stratigraphic position is given compared to the K/Pg boundary in the composite section of the Corral Bluffs. Numbered from bottom to top means that the locality is above the boundary, whereas numbered from top to bottom means that the locality is below the boundary.

• bed-level stratigraphic resolution

Environment/lithology: "floodplain"; mudstone

Size classes: macrofossils, mesofossils

Preservation: concretion, original phosphate

Collected in 2016-2019; reposited in the DMNH
