Where: Newfoundland and Labrador, Canada (48.5° N, 53.1° W: paleocoordinates 73.7° S, 89.0° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Port Union Formation, Ediacaran (635.0 - 541.0 Ma)

• No accurate radiometric dates have yet been published for successions from the Bonavista Peninsula, but the late Ediacaran units have been lithostratigraphically correlated with those of the Conception and St. John’s Groups from the Avalon Peninsula [37] (Fig. S1). If those correlations are correct, the widely cited date of 565±3 Ma obtained by U-Pb dating of zircons within a volcanic tuff from the Mistaken Point Formation (published without supporting isochrons in an abstract, ref. 24) would suggest that both the Back Cove locality and the Burnt Point paratype locality are younger than 565 Ma (Fig. S1).

• bed-level stratigraphic resolution

Environment/lithology: submarine fan; lithified siltstone

Size class: macrofossils

Preservation: mold/impression, replaced with pyrite

Reposited in the OUM

• Specimen remains uncollected in the field according to provincial law. Plastotype held in collections of Oxford University Museum of Natural History.
