Piker Hills Formation Ammonoids, Famennian, Canning Basin (Devonian of Australia)

Where: Western Australia, Australia (18.0° S, 125.5° E: paleocoordinates 21.4° S, 117.9° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Piker Hills Formation, Famennian (372.2 - 358.9 Ma)

• Paraclymenia- and Clymenia-Stufen; doIV and doV.

• formation-level stratigraphic resolution

Environment/lithology: marine; limestone and shale

• From ref. 10549: "The marginal-slope facies...consists of calcarenite, calcirudite, and megabreccia, while the basin facies...consists of interbedded shale, siltstone, calcarenite, and calcilutite." Monograph doesn't really give information needed to partition individual collecting localities into different lithologies.
