The Cretaceous unit cropping out in the map area consists of the late Cretaceous Owl Creek Formation with the Cretaceous-Tertiary boundary forming the upper contact. While studying the aftermath of the Cretaceous-Tertiary, or K-T, extinction, which wiped out the dinosaurs 65 million years ago, Jablonski noticed that many surviving lineages of plants and animals lingered a paltry few million years and then petered out. I would like to present the hypothesis of a direct link between chemical stress and a major mass extinction process, the Cretaceous-Tertiary (C-T) event, with the aim of providing a more holistic view on the potential of chemical stress on the evolutionary process. |
