This volume presents state-of-the-art papers on important topics and methods in the analysis of vertebrate microfossil assemblages. The minute remains of animals and plants have proven very useful to paleontologists as tools for dating large fossils, describing the environments which existed at the time the fossils were deposited, and identifying and mapping the extent of local floras and faunas, among other things. Due to the large sample sizes that can be obtained, the chance to recover rare taxa is much higher than it is during a search for skeletal remains. Analysis of the data produced from microvertebrate localities can address a wide range of questions as these papers clearly demonstrate.

"Vertebrate microfossil assemblages are collections of small, often-fragmented fossil remains, which usually contain a variety of taxa. Prior to the acceptance of taphonomy as part of mainstream paleontological studies, little attention was paid to microvertebrate fossil assemblages. Complete skeletons were far more popular as objects of study. Because of significant limitations in the collection and interpretation of information obtained from vertebrate microfossil assemblages, many researchers have expressed doubt as to the overall utility of microfossil-derived data. In large measure, this has been due to the lack of a standardized methodology for studying such sites. With recognition of the importance of microvertebrate assemblages to the study of paleobiology and evolution, methodology for studying such sites gradually evolved. Editors Sankey (California State Univ.) and Baszio (Univ. of Bonn, Germany) have divided this detailed work into two sections: "Importance of Microvertebrate Sites, Sampling, Statistical Methods, and Taphonomy" and "Guild Analysis, Ecological and Faunal Analysis, Biodiversity, and Paleobiogeopgraphy." In 13 well-referenced chapters, 17 authors present methodological approaches to the study of microfossil assemblages, results of several recent studies, and recommendations for future research. This book is sure to stimulate significant discussion among paleontologists and evolutionary biologists. Summing Up: Recommended. Upper-division undergraduate through research collections."

". . . Here, the editors have brought together a fine collection of papers primarily addressing [vertebrate microfossil assemblages]. . . . I would say that anyone working in the Late Cretaceous of North America would do well to purchase a copy, as would those who work on some of the taxa detailed within (small theropods, frogs, etc.). Kudos to the editors and authors on this interesting contribution!September 11, 2008"

"For several decades the study of vertebrate microfaunas has contributed greatly to our understanding of the evolution and paleobiology of fossil vertebrates. Despite the importance of such studies, the discipline has perhaps been viewed as slightly out of the mainstream. This is the first time that microfaunal studies have coalesced into a single volume. Hopefully it is a harbinger of an intellectual maturation, the coming-of-age of a discipline."
