• 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 conformably overlying Innommée member consists of 6 to 7 m of strata. At the east end of the island, these include laminated calcareous mudstone and massive to planar cross-stratified calcarenites of very fine to very coarse sand grade. Sections along the south coast are dominated by hummocky cross-stratified carbonates of fine to very fine sand grade, with subordinate micrites and coarse to very coarse sand-grade calcarenites."

Size classes: macrofossils, mesofossils

Preservation: original calcite
