GREGORY JOHN RETALLACK

 

Gregory Retallack is a Professor of Geological Sciences at the University of Oregon, where he has taught since 1981. His undergraduate studies at Macquarie University were followed by a PhD awarded from the University of New England, also in Australia, in 1978, and then postdoctoral studies at Indiana University from 1978 to 1981. His early career as a paleobotanist was derailed by discovery that fossil soils could reveal much about past vegetation. Most of his research has been devoted to development of the new field of paleopedology, including two textbooks "Soils of the past (1990, 2001)" and "A colour guide to paleosols (1997)". His research is dedicated to the proposition that soils have a fossil record, like other living things. Past studies have considered the role of soils in ape and human evolution in Kenya, grassland evolution in North America, dinosaur extinction in Montana, angiosperm evolution in Kansas and the Late Permian extinction in Antarctica. Current and future studies concern Devonian evolution of trees, Cambrian explosion on land, Precambrian atmospheres, and origin of life, with fieldwork in Pennsylvania, New York, Newfoundland, and Australia.
