Resumo |
Fossils of the deep marine ostracod, Clinocythereis australis Ayress & Swanson, 1991 occur within the Tambo River Formation, Gippsland Basin, southeastern Australia and record an approximately 6 Ma phase of late Miocene coastal ocean upwelling within this region. The presence of deep marine faunal elements within late Miocene Mitchellian strata is in contrast to the absence of such faunal elements in latest Miocene Cheltenhamian and younger marine strata of the Bass Strait hinterland. The absence of deep marine faunal elements in post-Mitchellian onshore strata is due to the Kosciusko Uplift, which transformed Bass Strait into a wholly shallow seaway placing adjacent coastal regions beyond the reach of ocean upwelling influences. |
