PBDB Collection

Craigleith vicinity, Georgian Bay area, Lake Simcoe area (Ordovician to of Canada)

Where: Ontario, Canada (45.5° N, 81.0° W: paleocoordinates 23.3° S, 55.6° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Belodina confluens conodont zone, Lower Member (Lindsay Formation), Edenian to Edenian (451.0 - 449.6 Ma)

• Formerly thought to be Trentonian, but now considered Edenian - Maysvillian (PJW 2017-04-18). Lindsay overlies Verulam Formation. Liberty (the author) separated the Collingwood from the Liberty (the formation), so this is the lower member.

• member-level stratigraphic resolution

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

• Possible shallow-water sedimentation.

• "The formation consists generally of grey to greenish grey, fine-grained, argillaceous limestone in beds from an inch to 2 feet thick. It also includes shale partings, as much as 2 inches thick, along most bedding planes. Interbedded are a few beds 8 to 12 inches thick, of medium-crystalline, crinoidal limestone and calcarenite, the latter commonly enclosing leses of fine to coarse conglomerate and breccia."

Size class: macrofossils

Collection methods: Fossils collected by Dr. J. F. Caley and/or the writer, identified by officers of the Geological Survey of Canada.
