New Campsite Locality, RTMP BB 100 (Cretaceous of Canada)

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

• Splay deposits typically comprise stacked sequences of interlaminated sands and siltstones separated by erosional surfaces, thus indicating repeated flooding and aggradation.
• BB 100 occurs in what appears to be a lateral "wing" of a 2.75 m thick sandstone body. Microfossils are concentrated in a 45 cm thick bed of poorly-sorted, contorted, very fine-to-fine-grained sandstone. Carbonaceous fragments are abundant.

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
