Five great mass extinction events are recognized in the past 500 million years. Although the extinction events are agreed upon, only the Cretaceous (K-T) event has produced enough positive evidence that suggests a bolide impact. Although impacts have been suggested for other extinction events, volcanism, climate change, changes in CO. 4References cited5ILLUSTRATIONS IGURE 1 Schematic stratigraphic section from northern Ohio to central Pennsylvania22 Chart showing age and correlation of stratigraphic units discussed in this report
