Paleocoordinates:14.1° South, 100.0° West (Wright 2013)
Basis of coordinate:based on nearby landmark
Geographic resolution:outcrop
Time
Period: Ordovician Epoch: Late Ordovician
10 m.y. bin: Ordovician 4-5 - Ordovician 5
Key time interval: Chatfieldian - Edenian

Stratigraphy
Geological group:Trenton Formation:Simard Member:Unit 4
Stratigraphic resolution:group of beds
Stratigraphy comments: PJW: Entered as "Chicoutimi Limestone" as authors didn't name it. However, it seems to be the uppermost Simard formation (Unit 4) given Desbiens & Lespérance (1989: fig. 1). The Edenian age was tentative, but this unit spans upper Chatfieldian - lower Edenian.
