Greg Retallack (PhD, 1978; University of New England, Armidale, Australia) is Director of the Condon Collection of Fossils and professor of earth sciences at the University of Oregon. A fellow of the American Association for the Advancement of Science and the Geological Society of America, he has written 14 books, including two textbooks, and published more than 270 refereed articles and 45 encyclopedia and informal publications. Greg is best known for pioneering the study of fossil soils and their role in major events in the history of life—such as human evolution in Kenya, dinosaur extinction in Montana, Permian plant extinctions in Antarctica, evolution of forests and early land plants, and origin of life in soils. Among his most frequently cited research is that demonstrating the role of grassland coevolution in global cooling culminating in the last Ice Age—research that has important implications for carbon farming in the current greenhouse crisis.
