Paleogeography is, at least, the partial synthesis of what is known about earth surface history through interpretation of the distribution of continents and oceans, paleotopography and paleobathymetry, distribution of erosional versus depositional settings, sedimentary environments, lithologies, and associations with paleoclimate, paleobiogeography, paleooceanography, among many other facets of earth history.  The Paleogeographic Atlas Project was conceived and directed by Alfred (Fred) M. Ziegler until his retirement in 2003. Allister Rees, former Atlas Project post-doc, currently at University of Arizona, has maintained the Paleogeographic Atlas Project lithofacies databases and placed them in the public domain. Paul Markwick, PhD of the Atlas Project, currently at Getech at the University of Leeds, has continued to update paleogeographic interpretations. Chris Scotese, also PhD of the Atlas Project, currently at University of Texas at Arlington, also has continued work on global paleogeographic reconstructions.  Other Paleogeographic Atlas Project members include, among others, Steve Barrett (BP-AMOCO), Karen Goldberg (Universidade Federal do Rio Grande do Sul), Fei Qi (China University of Geosciences), Mike Hulver (Saudi Aramco), Helen Morgans-Bell (Oxford), Nie Shangyou (Shell), Judy Parrish (University of Idaho), Ann Raymond (Texas A & M),  Dork Sahagian (Lehigh University), and David Sunderlin (Lafayette College). A large number of other graduate students, undergraduate students, visitors and research associates at The University of Chicago’s Department of the Geophysical Sciences contributed in many ways to the Atlas Project.
