Bleriot Ferry bonebed (Cretaceous of Canada)

Also known as Day Digs, BF

Where: Alberta, Canada (51.6° N, 112.9° W: paleocoordinates 59.3° N, 84.6° W)

• coordinate based on nearby landmark

• 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, carbonaceous siltstone

• "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 1993–1998; reposited in the TMP

Collection methods: quarrying, surface (in situ),
