BPS 468, Broom Point South (Cambrian of Canada)

Where: Newfoundland and Labrador, Canada (49.8° N, 57.9° W)

• Paleocoordinates: 7.5° N, 95.8° W (Wright 2013)

When: Lejopyge laevigata trilobite zone, Downes Point (lower) Member (Shallow Bay Formation), Marjumian (504.5 - 497.0 Ma)

• Kindle Zone 4 (preliminary, agnostoid-based evaluation by co-author) JA: correlates with Utah zones (see Fig. 6) that are entirely Middle Cambrian according to Gradstein et al. 2004. AGE: Dresbachian; refined by A. Hendy (6/2009) on the basis of biostratigraphic data (= Lejopyge laevigata zone).

•

•Actually, Dresbachian/Steptoan starts immediately after Lejopyge laevigata: this is Marjumian (PJW).

• bed-level stratigraphic resolution

Environment/lithology: offshore shelf; lithified, shelly/skeletal packstone and lithified grainstone

• member: coarse grained sequence of often amalgamated carbonate conglomerates. Specimens: equant casts of light-colored, bioclastic packstones and grainstones.

Size classes: macrofossils, mesofossils

Collection methods: Specimens from boulders
