Why Is Jack Sepkoski Influential?

(Suggest an Edit or Addition)

According to Wikipedia, Joseph John Sepkoski Jr. was a University of Chicago paleontologist. Sepkoski studied the fossil record and the diversity of life on Earth. Sepkoski and David Raup produced a new understanding of extinction events, by developing a statistical approach to the study of taxonomic diversification. They suggested that the extinction of dinosaurs 66 mya was part of a cycle of mass extinctions that may have occurred every 26 million years. But their most important contribution was the identification of the "Big 5" mass extinctions, events that have shaped the evolution of life on earth.
