Coelospira-Pacificocoelia Community, Lochkovian, Eastern Quebec (Devonian of Canada)

Where: Quebec, Canada (48.0° N, 66.0° W: paleocoordinates 31.3° S, 25.2° W)

• coordinate based on political unit

• local area-level geographic resolution

When: Lochkovian (419.2 - 410.8 Ma)

• Gedinnian

Environment/lithology: offshore; calcareous siltstone

• "Geographic and stratigraphic relations are consistent with BA 4-5 assignment...somewhat quiet-water...possibly lower in oxygen...but with enough current to disarticulate shells..."

•SEP environmental call based on given info

• "...shells occur scattered on bedding planes and are commonly disarticulated. Sediment has high organic content and is very thinly bedded to laminated calcareous siltstone. Coquinas and shell lenses generally absent."
