Where: Quebec, Canada (49.7° N, 63.8° W: paleocoordinates 22.0° S, 37.4° W)

• coordinate estimated from map

• small collection-level geographic resolution

When: Belonechitina gamachiana other zone, Prinsta Member (Ellis Bay Formation), Hirnantian (445.2 - 443.4 Ma)

• Same collection names are used by Jin 1989, Jin and Zhan 2008, and Li and Copper 2006.

• member-level stratigraphic resolution

Environment/lithology: lithified, nodular, shelly/skeletal, sandy, calcareous mudstone

• From Long (2007): “The Prinsta Member in its type section on the northeast coast consists of 9 m of fossilferous laminated and nodular calcaerous mudstones, with minor thin sandstone and limestone beds. At the west end of Anticosti Island, the member is 17-19 m thick and is dominated by highly fossiliferous subnodular to nodular thin-bedded micrites. Minor grainstones and plane to wavy laminated silstone beds are apparent near the top of the member.

Size classes: macrofossils, mesofossils

Preservation: original calcite

Collected by P. Copper; reposited in the GSC

Collection methods: bulk,
