kaolin quarry, between Willows and Readlyn (Cretaceous of Canada)

Where: Saskatchewan, Canada (49.6° N, 105.7° W: paleocoordinates 56.0° N, 77.7° W)

• coordinate estimated from map

• small collection-level geographic resolution

When: Whitemud Formation (Edmonton Group), Late/Upper Maastrichtian (70.6 - 66.0 Ma)

• bed-level stratigraphic resolution

Environment/lithology: wet floodplain; paleosol/pedogenic, ferruginous, brown, calcareous claystone and massive, white claystone

• "fining-upwards sequence of meandering streams"
• "1.5 m of white, structureless, blocky kaolinitic claystone which are overlain by 3.0m of beige to brown claystone with vertical carbonaceous rootlets and vertical tubes several centimeters long and a few millimeters in diameter composed of iron carbonate and iron oxide." Coprolites in upper 3 m of claystone. "In addition the > 100 mesh residue contains abundant silt-sized very angular quartz grains, coal fragments, and only rare well-rounded sand grains that are indicative of fluvial transport."

Size class: macrofossils

Preservation: coprolite
