Jim's Site, RTMP BB 115 (Cretaceous of Canada)

Also known as microvertebrate, DPP, Bonebed 115

Where: Alberta, Canada (50.8° N, 111.4° W: paleocoordinates 58.0° N, 75.9° 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"; intraclastic, brown, green, silty mudstone and carbonaceous sandstone

• muddy channel fill - described as an "estuarine channel"
• BB 115 fossils are present in a 2-3 cm thick intraclast bed at the lowest portion of a 3.5 m thick U-shaped unit of silty, organic-rich mudstone. Dark brown, massive-to-poorly laminated, very fine-grained siltstone with rare sandstone and carbonaceous laminae. phosphatic nodules common. Intra clasts are green, angular and breccia-like measure in some cases more than 5 cm in maximum dimension.

Size classes: macrofossils, mesofossils

Collected by J. McCabe in 1991; reposited in the TMP

Collection methods: bulk, surface (float),

• Weight % fossil content 0.1556 kg fossil weight, fossil/sample = 0.09% (Table 3, Eberth 1990). Screenwashed elements were collected using a screen with 9 openings per centimeter.
