Swan Hills Site 1 (Paleocene of Canada)

Also known as UAP-13

Where: Alberta, Canada (54.8° N, 115.5° W)

• Paleocoordinates: 64.5° N, 76.2° W (Wright 2013)

• coordinate stated in text

• small collection-level geographic resolution

When: Paskapoo Formation, Tiffanian (61.7 - 56.8 Ma)

• bed-level stratigraphic resolution

Environment/lithology: fluvial-lacustrine; gray, argillaceous shale and silty claystone

• "low-energy fluvial or lacustrine environment" (Scott 2006)
• "most of the rock at this locality is grey bentonitic shale; there are also thin lignitic layers and beds of friable limestone" (Russell 1967)

•"fossiliferous horizons [in the Swan Hills area] are predominantly montmorillonitic argillaceous shales, interbedded with or overlain by silty clays and calcareous shales" (Scott 2006)

Size class: mesofossils

Collected by L. S. Russell in 1965; reposited in the ROM
