B. M. R.-2 Laurel Downs (Devonian to of Australia)

Where: Western Australia, Australia (18.1° S, 125.3° E: paleocoordinates 25.2° S, 113.9° E)

• coordinate stated in text

• small collection-level geographic resolution

When: Fairfield Formation, Late/Upper Famennian to Late/Upper Famennian (364.7 - 346.7 Ma)

• Playford (1976, p.6): THe section penetrated by this drillhole includes the thickest known of the Fairfield Formation (490.8 m), even though the formation has eroded contact with overlying Late Carboniferous-Permian Grant Formation. According to Henderson et al. (1963) and Playford & Lowry (1966), the Fairfield Formatoin spans the bore's 76.2 - 567 m interval. The lower Fairfield contact at 567 m is not conspicous, and its placement could well be debatable.

• formation-level stratigraphic resolution

Environment/lithology: marine; lithology not reported

• Playford (1976, p.6): The Fairfield Formation is a poorly exposed calcareous sequence of biogenic limestones with recessive interbedded calcareous sandstone, silstone and shales.

Size class: microfossils

Collection methods: core, chemical,

• Playford (1976, p. 6): Samples of all 16 cores were cut at regular ( ca. 30 m) intervals in the formation.

•Additionally, Jones (in Veevers & Wells, 1961, pp.277-281) recognized three ostracod assemblages.
