Fox Coulee Quarry (Cretaceous of Canada)

Also known as FC, Midland Provincial Park, Day Digs

Where: Alberta, Canada (51.5° N, 112.7° W: paleocoordinates 59.1° N, 84.4° W)

• coordinate stated in text

• outcrop-level geographic resolution

When: Horsethief Member (Horseshoe Canyon Formation), Early/Lower Maastrichtian (70.6 - 66.0 Ma)

• bed-level stratigraphic resolution

Environment/lithology: wet floodplain; lenticular, brown, sandy siltstone

• "overbank wetlands in the lower coastal plain"; "these topographic lows were on interfluves and filled with material from that setting"
• "Each bonebed is hosted by massive to very poorly laminated, red brown to brown, sandy siltstones or silty sandstones, and each bonebed is rich in coalified plant fragments, amber, and dispersed, normally graded fossil bone and bone fragments. Each deposit is sharp-based and broadly lenticular in all directions where exposures allow assessment, and each deposit exhibits local occurrences of iron-carbonate cement and (or) concretionary ironstone development at, or near, the base."

Size classes: macrofossils, mesofossils

Collected in 1999–2001; reposited in the TMP
