Also known as SSF 110.3
Where: Quebec, Canada (46.8° N, 71.1° W: paleocoordinates 34.0° S, 82.2° W)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Bicella bicensis zone, Anse Maranda Formation, Dyeran (515.3 - 511.2 Ma)
• Bicella bicensis subzone, high in Olenellus zone; = Elliptocephala asaphoides zone

•"Rasetti (1946) noted that 3.3 m of shales and limestones with the Bicella bicensis assemblage are overlain by two ridge-forming limestone pebble–cobble debris flows (his units 2 and 4). The lower shales are assigned to the top of the “Anse Maranda Formation” (Lebel and Hubert, 1995), and the fossiliferous upper conglomerate marks the base of the Lauzon Formation in the Bacchus slice (Rasetti, 1946). The proposal of the “Anse Maranda Formation” (Lebel and Hubert, 1995) lacked such criteria as designation of a precise type locality, adequate lithologic description, and a detailed type section (e.g., North American Commission on Stratigraphic Nomenclature, 1983). For these reasons, its status as a formal lithostratigraphic unit is incomplete, and “Anse Maranda” is used in quotes in this report."
