Hespeler (Silurian of Canada)

Also known as = New Hope

Where: Ontario, Canada (43.4° N, 80.3° W: paleocoordinates 28.0° S, 43.3° W)

• coordinate based on nearby landmark

• local area-level geographic resolution

When: Guelph Formation, Ludlow (427.4 - 423.0 Ma)

• formation-level stratigraphic resolution

Environment/lithology: open shallow subtidal; dolomite

• "Environment: Probably the Janius Community of the Janius Community Group, as judged from the brachiopods, representing BA 3."

•SEP: the Guelph Formation is a very well known and intensively studied unit for petroleum. It is known among petroleum geologists as a "dolomitic reef" and has been the target of drilling in Ontario and the Michigan basin for many years. There is evidence for subaerial exposure during the development of the these "reefal" buildups that fringe the Michigan basin (Charbonneau, 1990)

• "Dolomite"

Size class: macrofossils

Preservation: cast
