Where: Tasmania, Australia (43.3° S, 145.1° E: paleocoordinates 43.3° S, 145.1° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Payntonian to Payntonian (489.5 - 485.4 Ma)

• STRATIGRAPHIC RELATIONS: Unnamed stratigraphic unit of Upper Carboniferous age. The Cambrian succession in this area occurs in a narrow fault slice with the base faulted against Precambrian slate and quartzite. The fossiliferous sequence is disconformably overlain by unfossiliferous sandstone and conglomerate, which is in turn overlain by the Ordovician Gordon Group (Jago and Brown 1989). AGE: late Late Cambrian (Payntonian-earliest Datsonian) on the north Australian biostratigraphic scale. STRATIGRAPHIC POSITION: Highest collection in succession. Collection from the upper part of the "grey micaceous siltstone" facies, about 75 m in thickness in total, near the middle of the section, immediately above the lower part of the same facies unit (PBDB 62280), above the "alternating yellow-green and purple siltstone" facies (PBDB 62277 and 62278). Collections are differentiated on the basis of facies on the stratigraphic column and range chart of Fig. 1 (Bao and Jago 2000) in the absence of stratigraphic heights, lithostratigraphic members or beds, or sample names. Additionally facies units are divided by the enterer into upper and lower halves to further differentiate the faunal succession.
