Sturgeon Heights Cottage Section (S1), Lot 9, Lake Simcoe area (Ordovician of Canada)

Where: Ontario, Canada (44.5° N, 78.7° W: paleocoordinates 25.1° S, 54.8° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Climacograptus americanus - Orthograptus ruedemanni graptolite zone, Lower Member (Verulam Formation), Chatfieldian (453.8 - 451.0 Ma)

• M5 - M6

• member-level stratigraphic resolution

Environment/lithology: deep subtidal; gray, argillaceous limestone and green shale

• "170 feet of grey and brownish grey, fine- and medium-grained, argillaceous and sublithographic limestone; and higher in the formation, 8- to 10-inch beds of grey, medium-crystalline, crinoidal limestone alternating with 2- to 3-foot beds of greenish grey shale. Most of the strata weather to thin, 1- to 2-inch beds and to a buff and rusty colour. The lowermost 10 to 30 feet are non-resistant and consist of an alternation of grey and brownish grey, fine-grained, argillaceous limestone and thin, 1-inch greenish shale partings."
