Rugosa of Redknife Fmn, upper member, Liard River/Bouvier River area, NWT (Devonian of Canada)

Where: Northwest Territories, Canada (62.0° N, 121.0° W: paleocoordinates 4.1° S, 37.5° W)

• coordinate estimated from map

• basin-level geographic resolution

When: upper Member (Redknife Formation), Frasnian (382.7 - 372.2 Ma)

• member-level stratigraphic resolution

Environment/lithology: marine; calcareous shale and argillaceous, sandy limestone

• "...a sequence of mainly calcareous beds assigned to the Redknife Formation. The lower member...the Jean-Marie Member, is a thin (2-12 m thick in outcrop), richly fossiliferous bioclastic limestone bearing a diverse rugosan assemblage...The unnamed upper member...is a recessive unit comprising calcareous shales with thin interbeds of more resistant argillaceous and sandy limestones..."
