Dicoelosia-Orthostrophella Community, Ludlow, West Point Fm., Gaspe (Silurian of Canada)

Where: Quebec, Canada (48.0° N, 65.0° W: paleocoordinates 28.6° S, 28.3° W)

• coordinate estimated from map

• local area-level geographic resolution

When: Anse a Loutre Member (West Point Formation), Ludlow (422.9 - 418.7 Ma)

• member-level stratigraphic resolution

Environment/lithology: deep subtidal shelf; gray lime mudstone

• "Shells almost entirely articulated...High diversity suggests normal oxygen...normal level of turbulence...BA 4. [P.-A. Bourque] finds that the Gaspe occurrences represent fore-reef facies of the lower reef compelx of the West Point Formation."

•SEP environmental call based on given information

• "fine grained matrix of micritic limestone...secondarily reddish due to weathering [originally gray]."

Collection methods: Comparison with other occurrences of this Community suggests that the elements listed are present here.
