Where: Alberta, Canada (52.0° N, 112.9° W: paleocoordinates 59.7° N, 84.5° W)
• coordinate based on nearby landmark
• small collection-level geographic resolution
When: Scollard Formation, Late/Upper Maastrichtian (70.6 - 66.0 Ma)
• Lower 4m of formation, likely derived from an interval 1–2 m above the base of the Scollard Formation, part of an inclined heterolithic stratification deposit that overlies a lower interval of clean sandstone (all part of a single channel succession). Within the top of the 30n magnetochron and slightly younger than 67 Ma
• bed-level stratigraphic resolution
Environment/lithology: "channel"; sandstone
Size class: macrofossils
Preservation: replaced with hematite
Collected in 2004; reposited in the TMP
Collection methods: surface (in situ),
• McGill University palaeontology field course in the summer of 2004, southern edge of microsite
