Ste. Anne de Chicoutimi (Ordovician to of Canada)

Also known as Chicoutimi-North

Where: Quebec, Canada (48.5° N, 71.1° W: paleocoordinates 24.3° S, 47.6° W)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Simard Formation, Kirkfieldian to Kirkfieldian (457.3 - 449.6 Ma)

• "Ordovician limestones, believed to be of Black River age, at the lower part of the section." (Flower, 1952 p. 48). Originally two limestone-bearing lithostratigraphic units have been described in the Chicoutimi area: the Tremblay Fm. and the Simard Fm. Since the Tremblay Fm. is restricted to the basal siliciclastics by Desbiens & Lespérance (1989, Can. J. Earth Sci. 26(6)) only the Simard Fm. is in line with the "description" given by Flower. The Simard Fm. appears to occupy a stratigraphic interval spanning the latest Kirkfieldian to Shermanian. (Desbiens & Lespérance, 1989).

Environment/lithology: gray lime mudstone

• " [...] the [Simard] formation is a predominantly dark gray calcilutite" (Desbiens & Lespérance, 1989).

Size class: macrofossils

Preservation: cast
