Our overall goal was to construct a subsurface transect of mid-Cretaceous strata that were deposited in the U.S. Western Interior Seaway (WIS), ranging from pelagic, organic-carbon rich, marine hydro-carbon source rocks in Kansas and eastern Colorado to nearshore, coal-bearing units in western Colorado and Utah. This transect of cores has provided the basis for paleoenvironmental interpretation of organic-carbon burial in an epicontinental, foreland basin setting. In part, the objectives of our study were motivated by the research emphases outlined by the Cretaceous Resources, Events and Rhythms (CRER) Project of the Global Sedimentary Geology Program. In particular, the papers in this volume focus on the Graneros Shale, Greenhorn Formation, Carlile Shale, and Niobrara Formation and equivalents in cores from six drillholes from western Kansas, southeastern Colorado, and eastern Utah. This series of cores provides unweathered samples and continuous, smooth exposures required for geochemical studies, mineralogical investigations, and biostratigraphic studies. Major objectives of the project covered in the collected papers include: (1) establishing the precise timing of sea level change, rates of subsidence, and facies change; (2) determining of controls on the accumulation, burial, and diagenesis of organic matter; (3) calibrating of depositional cycles using high-resolution stratigraphy; and (4) determining the paleogeography, paleoclimatology, and paleoceanography of the Western Interior Seaway and immediately adjacent landmasses. We gratefiilly acknowledge the many sources of funding and materials that supported these studies. Much of the research was fiinded by the Continental Scientific Drilling Program through the USGS and by the Department of Energy (DOE) through a grant to Penn State (DE-FG02-92ER14251). A core from an Amoco drillhole from western Kansas was released to the USGS in 1992, and description and analysis of this core plus that of a previously acquired well (Schock-Errington #1) in northwestern Kansas constitute the data base for the eastern end of the transect. Three holes that form the western end of the transect, funded by USGS energy programs, were drilled and continuously cored in June 1991 in the Kaiparowits basin near Escalante, Utah. In June 1992, a 700-foot hole, fiuided by DOE, was drilled and continuously cored near Portland, Colorado, east of the Florence oil field. This sequence, deposited in relatively deep water on the west side of the WIS, includes cycles of terrigenous-clastic and pelagic- marine sediments to contrast with the pelagic-carbonate-dominated cycles of Kansas and the clastic- dominated cycles of western Colorado and Utah. A second, 800-foot hole, also funded by DOE, was drilled in July 1992 about 10 miles southwest of the Portland hole in Pierre Shale, which serves as the reservoir for hydrocarbons in the Florence field. Formal descriptions of the cores are available in a computer data base published as USGS Open-File Reports. All tabulated data from the project are available through the National Geophysical Data Center (NGDC). We sincerely thank the many reviewers of individual papers in the volume for their concentrated efforts to maintain high tecimical standards and Peter Sholle for encouraging us to publish this volume through SEPM, the Society for Sedimentary Geology.

Kauffman. Erle was a collaborator in this project but was unable to complete his planned contribution to meet the deadline for the volume because of a major illness. However, Erle Kauffman's profound influence is evident in nearly every paper and we are indebted to him for helping us in so many ways. Armed with a strong intellect, boundless energy, and the gift of a silver tongue, Erle has captured the imagination of a horde of students and colleagues and ensnared many to study the spectacular but complicated Cretaceous geology of the Western Interior. Erle's own "holistic" efforts, aided by a cadre of talented students, combine grueling field work with classical principles of biozonation, radiometric dating, lithostratigraphy, and paleoecology to build a foundation for understanding Cretaceous events and basin evolution in the U.S. Western Interior. This substantial body of work includes early recognition of the utility of "Milankovitch" cyclicity in the rock record that provides an unprecedented quasi-20,000-year resolution of events preserved in sedimentary strata. Likewise, he has examined the imprints of anoxic events on faunal compositions and sedimentary structures of these strata, and has made a number of intriguing suggestions, including the hypothesis that anoxia -typically occurred at the sediment/water interface rather than within the water column as commonly assumed. Erle was also among the first to use sequence stratigraphic concepts in his studies--long before the techniques became a hallmark of sedimentary geology. In 1977, a landmark paper summarized many of these concepts as a series of enduring insights into the history of sea level and lithostratigraphy of Cretaceous Western Interior basin. He also found evidence for stepwise biotic extinctions accompanying the Cenomanian/Turonian "event," among many other contributions. Erle Kauffman has pursued both science and life with great vigor. His detailed knowledge and experience, infectious enthusiasm, and endless store of intriguing speculation coupled with boundless optimism and humor and profound generosity has affected us all. We wish him all the best as he rebounds from his unfortunate illness and hope that he will soon rejoin us in our quest to understand the intriguing strata of the Cretaceous Western Interior Seaway, of course with a few bottles of wine and strum of the ol' banjo.

ROBIN O’KEEFE ABSTRACT The taxonomic identity of two well-preserved polycotylid plesiosaur skeletons from the Pierre Shale of far northern Wyoming and southern South Dakota has been controversial since their discovery. Originally referred to Dolichorhynchops osborni, the material was almost immediate-ly christened Trinacromerum bonneri Adams 1997; more recently the material has been referred to Polycotylus. Recent preparation of the well-preserved skull of one specimen permits detailed examination of the cranial morphology of this animal for the first time, and allows for its inclusion in a cladistic analysis of the Polycotylidae.

About the Society of Vertebrate Paleontology I am a paleontologist and professor of Earth and Atmospheric Sciences at Indiana University. I represent the Society of Vertebrate Paleontology (SVP), as its Immediate Past President. SVP is the largest professional organization of paleontologists in the world and has over 2,200 members. Our mission is to advance the science of vertebrate paleontology; to support and encourage the discovery, conservation, and protection of vertebrate fossils and fossil sites; and to foster an appreciation and understanding of vertebrate fossils and fossil sites by the general public. SVP works with regulators and legislators around the world to keep scientifically important vertebrate fossils in the public trust because they provide the primary evidence for the history of vertebrate animals on our planet. We have a long, fruitful history of collaboration with the State of Utah, the Department of Interior, the US Forest Service, and the US Congress regarding protection of vertebrate fossils on state and federal public lands. We have worked especially closely with our federal partners on what is now known as the Paleontological Resources Preservation Act (PRPA) of 2009.
