At the Top of the Grand Staircase

Alan L. Titus is Monument Paleontologist at Grand Staircase–Escalante National Monument in Utah and Adjunct Curator, Natural History Museum of Utah.Mark A. Loewen is Adjunct Assistant Professor, Department of Geology and Geophysics, University of Utah and Research Associate, Natural History Museum of Utah.

...Rather than marking an end point, the volume is a foundational manuscript for ongoing research that will be indispensable to anyone researching the monument's prehistoric life. At the Top of the Grand Staircase is an essential volume for explorers who are continuing to search through what's left of Cretaceous Utah.(National Geographic Phenomena) [T]his work will be an important resource for library collections. It will be valuable to paleontologists and geologists who are working throughout the US and the world, not just this specific region. . . . Highly recommended.(Choice) This volume . . . provides a comprehensive foundation for future research ventures on Campanian-age strata worldwide. Editors Alan Titus and Mark Loewen have completed the excellent service of compiling a suite of various research topics—ranging from stratigraphic reviews and correlations to taphonomic studies—on this key scientific region.(Priscum)
