On each of the nearly 400 maps the old county lines are superimposed over the modern ones to highlight the boundary changes at ten-year intervals. Accompanying each map are explanations of boundary changes, notes about the census, & tocality finding keys. In addition, there are inset maps which clarify ??erritorial lines, a state-by-state bibliography of sources, & an appendix outlining pitfalls in mapping county boundaries. Finally, there is an index which lists all present day counties, plus nearly all defunct counties or counties later renamed-the most complete list of American counties ever published.

The 52 papers in this vary in content from summaries or state-of-knowledge treatments, to detailed contributions that describe new species. Although the distinction is subtle, the title (Vertebrate Paleontology in Utah) indicates the science of paleontology in the state of Utah, rather than the even more ambitious intent if it were given the title “Vertebrate Paleontology of Utah” which would promise an encyclopedic treatment of the subject. The science of vertebrate paleontology in Utah is robust and intense. It has grown prodigiously in the past decade, and promises to continue to grow indefinitely. This research benefits everyone in the state, through Utah’s muse ums and educational institutions, which are the direct beneficiaries.
