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. This locality has ferruginous concretions, fossil charcoal, and flat 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. | |||
