RTMP BB 119 (Cretaceous of Canada)

Also known as Turtle Pond, DPP, Bonebed 119, RTMP Quarry 159, U009

Where: Alberta, Canada (50.7° N, 111.5° W: paleocoordinates 58.0° N, 76.0° 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)."

• bed-level stratigraphic resolution

Environment/lithology: "channel"; lag, fine-grained, pebbly, intraclastic, silty sandstone

• Characterized as in-channel, coastal plain. Facies association = trough cross-stratified sandstones. Upper flow-regime, tractional plane beds fromed during flood stage. Lag deposits, or plane bed deposits that show horizontal-planar stratification, bed thicknesses exceeding single pebble diameters, normal graded or fining upward texture, and matrix-supported clasts.

•The disconformity in southern Alberta records a Cordilleran uplift event west of the Park.

• "BB 119 occurs at the lateral margin of a broadly dish-shaped (in cross-section) multistoried sandstone body (Fig. 6H). At the fossil site, the sandstone body is only 20-50 cm thick and comprises ripple-laminated, silty, fine-grained sandstones (Fig. 6I). Fossils occur at the base of this interval overlying a massive mudstone and in association with massive, mudstone-intraclast-rich sandstone.

Size classes: macrofossils, mesofossils

Collected by Brinkman, Currie, Maier in 1984–1985; reposited in the TMP

Collection methods: bulk, surface (float), sieve,

• Screenwashed elements were collected using a screen with 9 openings per centimeter.
