Abstract

Nineteen samples were submitted by the Water Conservation and Irrigation Commission of New South Wales, from Bore No.92859on Mr.W.J. Davis property Hewart Downs via Tibooburra in north-western New South Wales. This bore is located at 29 36'S,141 17'E. Samples were taken at 50 feet intervals between the depths of 250 feet and 1100 feet. Operations have ceased at the moment, because of mechanical troubles. However, the Water Conservation and Irrigation Commission are hopeful that the bore will be continued Any palaeontological information that can be derived from bores in this part of New South Wales is important.. at the present time, because it helps in the elucidation of the subsurface stratigraphy of the Lower Cretaceous in that part of the Great Artesian Basin. An excellent suite of Lower Cretaceous foraminifera, especially calcareous species, is present from 450 feet down to 1100 feet. Further support for a Lower Albian age for these beds is given by the occurrence of the megaspore pyrobolospora, reticulata Cookson and Dettman, 1958 (determined by P.R. Evans)which is characteristic of subsurface Lower Albian beds in bores in South Australia, Victoria, New South Wales and Queensland.
