Also known as Griffith Farm

Where: Alberta, Canada (51.9° N, 113.0° W)

• Paleocoordinates: 64.0° N, 68.1° W (Wright 2013)

• coordinate stated in text

• small collection-level geographic resolution

When: Scollard Formation, Lancian (70.6 - 66.0 Ma)

• layer "from less than 1 foot in thickness to about 3 feet"

•all of the localities are within 27 m above the Kneehills Tuff, dated at "65-66" Ma according to Clemens et al. 1979 - this site is actually 43 ft above the tuff

• bed-level stratigraphic resolution

Environment/lithology: terrestrial; lithified claystone and siltstone

Size class: mesofossils

Collected by W. A. Clemens in 1963-1967

Collection methods: bulk, surface (float), surface (in situ), sieve,

• because this quarry yielded a large majority of specimens, specimen counts assume that an absolute minimum number of listed specimens come from the other localities

•NISP 818 (maximum)

•Schowalteria specimen was found "in situ" but some parts of it were "recovered by carefully searching the outcrop and screen-washing the talus"
