Kindle boulder #357, B Biofacies, Downes Point Mb, - Young and Ludvigsen 1989 (Cambrian of Canada)

Where: Newfoundland and Labrador, Canada (49.3° N, 65.6° W)

• Paleocoordinates: 10.0° N, 101.0° W (Wright 2013)

• coordinate based on political unit

• outcrop-level geographic resolution

When: Ptychagnostus gibbus zone, Downes Point Member (Shallow Bay Formation), Solvan (510.2 - 504.5 Ma)

• Boulder #357 is from the Bathyuriscus Biofacies. While this monograph deals with the Kindle Zone 1, fauna of the Kindle Zones 2-5 can be found in Westrop et. al 1996. The Downes Point Member is about 100m thick and the general paleoenvironment is a shelf edge/upper slope environment which transported fossils as debris flows forming a deep water sediment apron..

• group of beds-level stratigraphic resolution

Environment/lithology: slope; lithified packstone and lithified wackestone

• The Bathyuriscus Biofacies has a lithology of packstone and wackstone.

Size classes: macrofossils, mesofossils

Preservation: recrystallized

Collection methods: Not all boulders were assignable to a biofacies and only trilobites were described, however other taxa are not known to be omitted since there is no mention of them in the text. The trilobites described here are part of the C. H. Kindle Collection at the Geological Survey of Canada.
