Where: Queensland, Australia (27.6° S, 152.8° E: paleocoordinates 58.5° S, 101.2° E)

• coordinate stated in text

• outcrop-level geographic resolution

When: Norian (228.0 - 208.5 Ma)

• Purdy & Cranfield (2013) reported an unpublished SHRIMP date of 226±2 Ma for the Brisbane Tuff. Therefore, the Blackstone Formation may be considered younger than 226 Ma in absolute age. Thus, the Ipswich Coal Measures above the Brisbane Tuff, which is to say, the succession from the Mount Crosby Formation to the top of the Blackstone Formation must now be considered Norian.

• bed-level stratigraphic resolution

Environment/lithology: lacustrine - small; lithified shale

Size classes: macrofossils, mesofossils

Preservation: mold/impression
