Where: New South Wales, Australia (33.2° S, 148.7° E: paleocoordinates 11.0° S, 173.9° E)

• coordinate based on political unit

• local area-level geographic resolution

When: Fairhill Formation, Pridoli to Pridoli (423.0 - 393.3 Ma)

• Flora and fauna suggest Pridoli or early Gedinnian age.

• formation-level stratigraphic resolution

Environment/lithology: marine; micaceous shale and argillaceous sandstone

• Cowra Trough.
• "[Formation consists of] 1070 m of greywackes, shales, and volcanic breccias...Interbedded with greywackes in lowerr part of formation are well-lithified brown and grey siltsontes whereas high in the formation beds of soft micacous shale occur. [Fossils are in uppermost horizons of formation and include vascular plant fragments.]"
