Abstract

A small collection of marine Lower Cretaceous Mollusca from Mount Samuel area, central Western Australia, consists of six genera and seven species which are known from the Roma Formation beds of the Great Artesian Basin. It is suggested that a communicating seaway existed between the Great Artesian Basin and Mount Samuel area during Aptian times. Migration of marine organisms probably took place along a southern route through Officer and Eucla Basins, but may have possibly proceeded directly to the west from Rumbalara. It is also suggested that at the same time another seaway existed between Mount Samuel area and the Dampier Peninsula.The sediments of the Great Artesian Basin occur in two areas in the Northern Territory, viz, in the vicinity and to the east of Rumbalara, at the southern extreme of the Northern Territory where they are of Aptian age and are correlated with beds of Roma Formation in Queensland; and up to about one hundred miles south of the Gulf of Carpentaria, close to the Queensland border, where they are of Aptian and of Upper Albian age and can be correlated with the Roma and Tambo Formation beds of Queensland.
