Also known as microvertebrate, DPP, Bonebed 100, RTMP L0406
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)" where positive numbers are above and negative below.
• bed-level stratigraphic resolution
Environment/lithology: crevasse splay; fine, carbonaceous sandstone
Size classes: macrofossils, mesofossils
Collected by J. Walper; reposited in the TMP
Collection methods: bulk, surface (float), sieve,
• Screenwashed elements were collected using a screen with 9 openings per centimeter. Described as having been collected "long ago" by Currie 2005
