Most of three field seasons (1960-1962) were spent examining the Cretaceous sediments and fossils of the northern portion of the Northern Territory. These sediments were traced into north-western Queensland. In addition I spent the 1963 winter season in the field as a member of a field party which, under the leadership of A. T. Wells, mapped a large area between Alice Springs and the South Australian border. My task on that occasion was the mapping of the post Devonian sediments on the Kulgera and Finke 1: 250,000 Sheet areas; these sediments include the Cretaceous Rumbalara Shale. The bulk of the first part of this Bulletin is devoted to the presentation of geological data on the Cretaceous sediments of the northern portion of,the Northern Territory, which will be presented under the title of Mullaman Beds. The Cretaceous fossils are described in Part 2 (p. 53 onwards). Many conclusions reached and presented in this Bulletin would not have been possible without datings obtained from fossils collected during the survey. The Cretaceous sediments of the Northern Region are contained in about fifty 1: 250,000 Sheet areas. Outcrops are scarce or hard of access over much of, this region, and more time could profitably be spent collecting additional information. Approximations made for lack of time in the field will become apparent with more detailed work in future years. The Cretaceous sediments of the Southern Region are much less complex; they are briefly described under the titles of Rumbalara Shale and sediments of the Hay River area. The ages of the subdivisions are given in general terms, because the faunas do not permit precise determination in terms of standard zones (see Fig. 24).
