This thesis has two main objectives. The first is a full scale analysis of both the stratigraphy and stratigraphlcal palaeontology of the Carboniferous rocks in the Yarrol Basin of Queensland and the Western Belt of New South Wales, The data of previous workers are re-assessed in the light of more detailed systematic palaeontology, several new stratigraphic sections are described, and several new faunas are dealt with in detail. The second objective is a new correlation of the Permian sections of Queensland and northernmost New Soutii Wales, the basic palaeontological data being derived from a study of the almost ubiquitous spiriferids commonly referred to as Martlniopsis.
One section of the work, viz, that on the Lower Carboniferous fauna at Watts, Babbinboon, has already been published (Jour. Palaeont, Vol, 31, no.l, 1957), The section on the Permian was written for separate publication and no attempt has been made to integrate it with the preceding Carboniferous sections.
I have received help with numerous problems from various people whose assistance is acknowledged at the appropriate points in the text. Special mention, however, must be made of the continuing interest shown by both Dr, Dorothy Hill and Professor Voisey,
