Also known as Dave's II, Bonebed 105, DPP
Where: Alberta, Canada (50.8° N, 111.5° W: paleocoordinates 58.1° N, 76.1° W)
• coordinate stated in text
• outcrop-level geographic resolution
When: Oldman Formation (Belly River Group), Middle Campanian (83.5 - 70.6 Ma)
• Microvertebrate sites of Brinkman (1990) are "...placed in stratigraphic sequence by reference to a disconformity located about sixty meters below the base of the Lethbridge Coal (Eberth, 1990). The stratigraphic position of each site is expressed in terms of meteres above or below the disconformity (Fig. 2, Brinkman, 1990)."
• bed-level stratigraphic resolution
Environment/lithology: "channel"; tabular, lag, pebbly, intraclastic, silty sandstone
Size classes: macrofossils, mesofossils
Collected by D. Brinkman; reposited in the TMP
Collection methods: bulk, surface (float), sieve,
