Where: Quebec, Canada (49.2° N, 62.7° W: paleocoordinates 22.9° S, 33.4° W)

• coordinate stated in text

• small collection-level geographic resolution

When: Ferrum Member (Jupiter Formation), Telychian (438.5 - 433.4 Ma)

• Collection A347 of Dewing 1999. Same collection names are used by Jin 1989, Jin and Zhan 2008, and Li and Copper 2006.

• bed-level stratigraphic resolution

Environment/lithology: lithified, hardground, calcareous lime mudstone and lithified, calcareous grainstone

• Member description taken from 2007 Long. Tempestite frequency curves: a key to Late Ordovician and Early Silurian subsidence, sea-level change, and orbital forcing in the Anticosti foreland basin, Quebec, Canada. Can. J. Earth Sci. Vol. 44, 413-431. "Along the south coast the Ferrum Member is at least 32 m thick. It is characterized by marked lithologic variability with thin-bedded micrite with calcareous mudstone partings, thin calcarenites, hardgrounds, and intraformational conglomerates."

Size classes: macrofossils, mesofossils

Preservation: original calcite
