A0068 (Silurian of Canada)

Where: Quebec, Canada (49.7° N, 63.4° W: paleocoordinates 21.5° S, 36.3° W)

• coordinate stated in text

• small collection-level geographic resolution

When: Oulodus nathani conodont zone, Fox Point Member (Becscie Formation), Rhuddanian (443.4 - 440.8 Ma)

• Collection A68 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, 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 basal Fox Point member is dominated by thin-bedded sets of relatively clean unlaminated and laminated micrite, which are separated by thin sets of siliciclastic-rich carbonate mudstones. The lower part of the unit contains abundant discontinuous grainstone and carbonate sandstone units, with hummocky cross-stratification and local development of ball-and-pillow structures in proximity to stepped irregularities on the basal flooding surface (Fig. 3E; Long and Copper 1994). The Fox Point member thins from 22 m in the west to as little as 3.6 m in the east (Sami 1989)."

Size classes: macrofossils, mesofossils

Preservation: original calcite
