Also known as Bear Creek coal field or Red Lodge coal field, Carbon County, Montana (Fort Union Formation)

Where: Montana (45.0° N, 109.0° W: paleocoordinates 52.3° N, 79.0° W)

• coordinate based on political unit

• local area-level geographic resolution

When: Fort Union Formation, Cretaceous to Cretaceous (145.0 - 66.0 Ma)

• The exact formation in which the coal beds of the is field belong appears to have been rahter difficult to determine, and for many years there has been considerable controversy over the stratigraphic position of the Fort Union formation, placing it in either the top of the Cretaceous or the base of the Tertiary. (In many localities the formation lies immediatley above the Cannonball member of the Lance formation.)

• group of beds-level stratigraphic resolution

Environment/lithology: mire or swamp; coal

Size class: microfossils

Preservation: charcoalification, coalified, original sporopollenin

Collection methods: surface (in situ), chemical,
