Kirkfield Quarry, lots 31-32, off of highway 503, near Kirkfield, Lake Simcoe Ar (Ordovician of Canada)
Where: Ontario, Canada (44.6° N, 79.0° W: paleocoordinates 24.8° S, 54.9° 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."
