Also known as Isle Jesus, Jesus Island, Hochelaga Archipelago, St. Lawrence Lowland
Where: Quebec, Canada (45.6° N, 73.7° W: paleocoordinates 26.0° S, 50.9° W)
• coordinate based on political unit
• small collection-level geographic resolution
When: Terrebonne Member (Tetreauville Formation), Shermanian to Shermanian (460.9 - 449.5 Ma)
• "Terrebonne formation" Flower (1952). When Flower wrote the paper used as reference here, the Terrebonne was considered a seperate formation. Today it is regarded as a facies variation of the Tetreauville Fm. (see Harland & Pickerill, 1982, Geol. Mag. 17; see also comments on lithology). Nevertheless it is given here as a member of the Tetreauville in order to include the name in the collection record. The Tetreau(lt)ville Fm. is Shermanian to Edenian in age according to Melchin & Legault (1985, Palynology 9).
• bed-level stratigraphic resolution
Environment/lithology: deep subtidal shelf; burrowed, nodular, rubbly, argillaceous limestone and shale
Size class: macrofossils
Preservation: cast
