• 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 Prinsta Member in its type section on the northeast coast consists of 9 m of fossiliferous laminated and nodular calcareous mudstones, with minor thin sandstone and limestone beds. At the west end of Anticosti Island, the member is 17 to 19 m thick and is dominated by highly fossiliferous subnodular to nodular thin-bedded micrites. Minor grainstones and plane to wavy laminated siltstone beds are apparent near the top of the member."

Size classes: macrofossils, mesofossils

Preservation: original calcite
