Where: Quebec, Canada (50.2° N, 63.6° W: paleocoordinates 27.2° S, 46.8° W)
• coordinate estimated from map
• local area-level geographic resolution
When: Bathyurus granulosus/Ceraurinella nahanniensis trilobite zone, upper Member (Mingan Formation), Whiterockian (470.0 - 457.3 Ma)
• Bathyurus granulosus (nearshore biofacies) and Ceraurinella nahanniensis (open shelf biofacies) biozones are partially concurrent (Tremblay and Westrop 1991).
Environment/lithology: lithology not reported
Size class: macrofossils
Collected by T.E. Bolton in 1978; reposited in the GSC
• Paper states that: "Field work for the present report was undertaken in 1966, 1971, and 1972 by F. C. Shaw and in 1978 by T. E. Bolton, M. J. Copeland, and G. S. Nowlan. Additional material was supplied by A. A. Petryk, A. Desrochers, and S. Desbiens." GSC locality numbers all likely to have been collected by Bolton and others in 1978 (Shaw collections are listed separately).
