Where: Newfoundland and Labrador, Canada (46.6° N, 53.2° W: paleocoordinates 74.6° S, 94.7° E)
• coordinate estimated from map
When: Avalon other zone, Briscal Formation (Conception Group), Ediacaran (635.0 - 541.0 Ma)
• Bed BS-1 is directly above BR-5, so I am using that for both the upper and lower bounds.

Environment/lithology: basinal (siliceous); lithified, tuffaceous sandstone
Size class: macrofossils
Preservation: mold/impression
Reposited in the ROM
