A323 (Silurian of Canada)

Where: Quebec, Canada (49.1° N, 61.7° W: paleocoordinates 21.6° S, 34.4° W)

• coordinate stated in text

• small collection-level geographic resolution

When: Richardson Member (Jupiter Formation), Aeronian (440.8 - 438.5 Ma)

• Collection A323 of Dewing 1999. Same collection names are used by Jin 1989, Jin and Zhan 2008, and Li and Copper 2006.

•The collection is noted by Dewing to be from the Richardson to Cybele mbrs. We marked here the lowest Mbr. because we do not know which one the fossils came from.

• bed-level stratigraphic resolution

Environment/lithology: lithified, argillaceous limestone and lithified, calcareous lime mudstone

• 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. "The Richardson Member consists of 25 m of predominantly argillaceous limestones in the lower part, with resistant layers of micrite and calcarenite occurring in increasing abundance toward the top."

Size classes: macrofossils, mesofossils

Preservation: original calcite

Collected by P. Copper
