Late Ordovician Articulate Brachiopods from the Red River and Stony Mountain Formations, Southern Manitoba

2001

The Late Ordovician Epoch was marked by although the presence of the distinctive receptaculitid one of the two greatest sea-level rises and floodings of algae and the giant gastropod Maclurites had been used the North American paleocontinent in Phanerozoic by pioneer workers to date Ordovician rocks in the time, accompanied by rapid diversification of inverte- area. [...] During the Devonian and Mississippian peri- Late Ordovician erosion has removed the deposits ods, the Williston Basin became part of the giant Elk from the northeastern part of the basin (i.e., north- Point Basin, stretching from the southern Northwest central Saskatchewan and much of western Manitoba). [...] Toward the lar to the Gunn Member in lithology and fossil content, centre of the basin, in southern Saskatchewan (Well 7- except that it is dolomitized and usually weathers yel- 28-4-4W2), the equivalent of the Selkirk Member is the lowish tan in colour.
