The Viability of the Catastrophism Theory in Dinosaur Extinction

Abstract: An 8 page consideration of the theory of catastrophism in relation to the dinosaur extinction which occurred during the Cretaceous and Tertiary periods. Weighs the geologic evidence of such an event against the environmental effects which would have occurred to contend that such an event would have had much further effects than on the dinosaurs alone. If catastrophism resulted in the extinction of the dinosaurs it would have resulted in widespread extinction of other species as well. Concludes that this fact discounts the validity of catastrophism and suggests that gradual environmental changes and the effects of competition with other animals led to this extinction.
