From the distribution and general composition of marine sedimentary rocks and their faunas in the Gondwana area, I have concluded that the widespread occurrence of marine rocks of Paleozoic and Mesozoic ages, especially in Western Australia, southern Africa, and Antarctica, is inconsistent with the hypothesis of Gondwanaland. Historically, this hypothesis was based on the assumption, now proved erroneous, that most Paleozoic and Mesozoic rocks in Southern Hemisphere (Gondwana) continents were of continental origin.

The general theme of this publication is the assessment and reassessment of various data, observations, and ideas about the earth as they relate to the concept that has come to be known as plate tectonics. Much widely scattered material was brought together for this publication, and its 24 papers contain an abundance of worldwide references that are important in studying plate tectonics.
