R432-5-8, Upper Lmst. Member (Cambrian of Canada)

Also known as Route 432 section 5

Where: Newfoundland, Canada (50.0° N, 56.6° W: paleocoordinates 40.5° S, 72.4° W)

• coordinate estimated from map

When: Paterina brachiopod zone, Upper Limestone Member (Forteau Formation), Dyeran (516.0 - 513.0 Ma)

• Assemblage 2 zone (Paterina zone)

Environment/lithology: reef, buildup or bioherm; grainstone and carbonaceous rudstone

• It consists of a lower division comprised of archeocyathid bioherms and grainstone

•and an upper heterolithic division predominantly of carbonate with some metre-thick siliciclastic intervals. The lower division begins with a lower 7 m interval of archeocyathid bioherms, grainstone and lesser microbial boundstone. It is

•succeeded by about 18 m of oolitic, skeletal and Salterella-rich grainstone in which are scattered a few archeocyathans and broken oncoliths. Beds of matrix supported carbonate rudstone (matrix of shale, mudstone, or dolostone) occur in the lower interval and mark its base at MSM.

Size classes: macrofossils, mesofossils
