title: Multiple factors in the reptile extinctions of the Cretaceous period.
abstract: The selective extinction of the dinosaurs and other giant reptiles has long been a topic of speculation and controversy. Everyone is familiar with the theory of the giant bollide colliding with Earth. But, would it not be more likely that that multiple factors acted over a relatively long period of time to produce this mass extinction?
