C661 (Silurian of Canada)

Where: Quebec, Canada (49.6° N, 63.3° W: paleocoordinates 22.4° S, 33.8° W)

• coordinate stated in text

• small collection-level geographic resolution

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

• Collection C661 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, bioturbated, hardground, 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 32 to 34 m thick Cybèle Member is characterized by thin- to medium-bedded, predominantly barren micrites with minor thin calcarenites. Bioturbation and hardground surfaces are common. Laminated calcareous mudstones may be present locally but are poorly exposed."

Size classes: macrofossils, mesofossils

Preservation: original calcite
