Also known as "The Crater", QML 78
Where: Queensland, Australia (24.8° S, 148.0° E: paleocoordinates 58.0° S, 136.0° E)
• coordinate estimated from map
• outcrop-level geographic resolution
When: Arcadia Formation (Rewan Group), Induan (252.2 - 251.2 Ma)
• Warren et al. (2006) argued that the Arcadia Formation is likely earliest Triassic in age based upon SHRIMP, U/Pb and microflora evidence that the conformably underlying Sagittarius Sandstone of the Rewan Group is largely Permian in age.
•
•"Lower beds of the upper part of the Rewan Formation of the Mimosa Group [...] Howie (1972) has fully discussed the geological provenance and the reasons for assigning an Early Triassic age to the level from which the material is drawn." (Bartholomai, 1979)
•
•"Lower Arcadia Formation, Rewan Group, Early Triassic (Scythian A1 of Cosgriff, 1984). Age of fauna equivalent to Lystrosaurus Zone of southern Africa." (Warren & Hutchinson, 1990).
•Notes: The term "Mimosa Group" is obsolete and the former Rewan Formation was reranked to group status. Consequently, the original lithostratigraphic entries of this collection (which were following Bartholomai, 1979) have been changed (TL).
•
•According to Veevers et al. (1994, in Veevers & McA. Powell (eds.), GSA Mem. 184) the Arcadia Fm. constitutes the upper part of the Rewan Group. Hence, stratigraphic descriptions by Bartholomai (1979) and Warren & Hutchinson (1990) appear to refer approximately to the same stratigraphic level.
