Also known as microvertebrate, Bonebed 54, DPP
Where: Alberta, Canada (50.8° N, 111.6° W: paleocoordinates 58.1° N, 76.1° W)
• coordinate stated in text
• outcrop-level geographic resolution
When: Dinosaur Park Formation (Belly River Group), Late/Upper 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: fine channel fill; silty, carbonaceous sandstone and mudstone
Size classes: macrofossils, mesofossils
Collected by L. J. Strong in 1985; reposited in the TMP
Collection methods: bulk, surface (float), sieve,
• Screenwashed elements were collected using a screen with 9 openings per centimeter.
