Stratigraphy comments: In the Tyers River Subgroup.
Lithology and environment
Lithology description: The Locmany Member of the Rintoul Creek Formation consists of interbedded quartzose sandstones and fossiliferous siltstones. The lower portion of the Locmany Member contains a few thin, discontinuous, conglomerates and bituminous coal seams. The Locmany Member is the source of the majority of the fossils examined in this study. Localities 17A-K are from claystones, siltstones, and sandstones. The beds contain roots, horizontal burrows, plant foliage (identifiable), wood/axes (>30 cm long), ferruginous concretions, flat laminae, wavy laminae, fragmentary foliage (unidentifiable), fossil charcoal, and cross-laminae.
Environment:terrestrial indet. Tectonic setting:rift
Geology comments: The Gippsland Basin is a roughly east-west orientated rift and epicratonic sag basin located along the southeastern margin of Victoria, Australia. The basin was initiated in the latest Jurassic or Early Cretaceous as rifting propagated along a roughly west-east axis between Austrailia and Antarctica.
