Also known as microvertebrate, DPP, Bonebed 108
Where: Alberta, Canada (50.8° N, 111.6° W: paleocoordinates 58.1° N, 76.2° 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: channel lag; intraclastic sandstone
Size classes: macrofossils, mesofossils
Collected by W. Marshall; reposited in the TMP
Collection methods: bulk, surface (float),
• Weight % fossil content 0.5935 kg fossil weight, fossil/sample = 0.35% (Table 3, Eberth 1990).
•Screenwashed elements were collected using a screen with 9 openings per centimeter.
