Arrowie Syncline, Moro section, sample 904.5 (Cambrian of Australia)

Where: South Australia, Australia (30.7° S, 139.2° E: paleocoordinates 17.4° N, 161.2° W)

• coordinate stated in text

• outcrop-level geographic resolution

When: Winnitinny Creek Member (Wilkawillina Limestone Formation), Atdabanian (521.0 - 516.0 Ma)

• Terreneuvian, Stage 2

•the paper discussed that the Winnitinny Creek member should be equivalent to the base of the Stage 3, which equals to the beginning of Atdabanian.

• group of beds-level stratigraphic resolution

Environment/lithology: lagoonal or restricted shallow subtidal; limestone

• succession of massive carbonate, bioclastic grainstones alternating with micritic and microbial laminated carbonates.135 m thick and suggests a rapid change in depositional environment from a moderate to high energy, shallow water biohermal platform to a more restricted, low energy, intrashelf, and possibly slightly deeper lagoonal environment.

Size class: macrofossils
