Geography

Country:	Australia	State/province:	Queensland
Coordinates:	27.6° South, 152.8° East (view map)
Paleocoordinates:	58.5° South, 101.2° East
Basis of coordinate:	based on nearby landmark
Geographic resolution:	outcrop

Time

Period:	Triassic	Epoch:	Late/Upper Triassic
Stage:	Norian	10 m.y. bin:	Triassic 4
Key time interval:	Norian
Age range of interval:	227.00000 - 208.50000 m.y. ago

Stratigraphy

Stratigraphic resolution:	bed
Stratigraphy comments: "at the bottom of the Ipswich Series" well below the Denmark Hill bed Carnian according to Barone-Nugent et al. 2003. Purdy & Cranfield (2013) reported an unpublished SHRIMP date of 226±2 Ma for the Brisbane Tuff.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.

Lithology and environment

Primary lithology:	lithified "shale"
Environment:	pond	Tectonic setting:	rift
Geology comments: Ipswich basin; transtensional rift in intermontane setting. Basin geometry affected by strike-slip movement along West Ipswich fault. Ipswich coal measures deposited near end of rifting phase.

Taphonomy

Modes of preservation:	body,adpression
Size of fossils:	macrofossils,mesofossils

Collection methods and comments

Reason for describing collection:	taxonomic analysis
Museum repositories:	UQ
Collection method comments: University of Queensland Department of Geology collection
