Book Description
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.

Book Description
This study explores the origin of concentrations of small fossil bones and teeth preserved in (1) pond/lake and (2) active channel deposits in the Judith River Formation of Montana. Vertebrate fossils recovered from both types of assemblages are similar in shape and rounding, but channel concentrations are better sorted. In flume experiments, bone concentrations formed when an active flow was directed through sediment beds with initially dispersed bone material. The coarse bone fraction was minimally transported, while the fine fraction was winnowed to distal parts of the flume. These results suggest channel assemblages may be derived from pre-existing pond/lake assemblages.

Book Description
The vertebrate fossil record extends back more than 500 million years, and bonebeds—localized concentrations of the skeletal remains of vertebrate animals—help unlock the secrets of this long history. Often spectacularly preserved, bonebeds—both modern and ancient—can reveal more about life histories, ecological associations, and preservation patterns than any single skeleton or bone. For this reason, bonebeds are frequently studied by paleobiologists, geologists, and archeologists seeking to piece together the vertebrate record. Thirteen respected researchers combine their experiences in Bonebeds, providing readers with workable definitions, theoretical frameworks, and a compendium of modern techniques in bonebed data collection and analysis. By addressing the historical, theoretical, and practical aspects of bonebed research, this edited volume—the first of its kind—provides the background and methods that students and professionals need to explore and understand these fantastic records of ancient life and death.

Book Description
Easily distinguished by the horns and frills on their skulls, ceratopsians were one of the most successful of all dinosaurs. This volume presents a broad range of cutting-edge research on the functional biology, behavior, systematics, paleoecology, and paleogeography of the horned dinosaurs, and includes descriptions of newly identified species.

Book Description
This volume focuses on the broad pattern of increasing biodiversity through time, and recurrent events of minor and major ecosphere reorganization. Intense scrutiny is devoted to the pattern of physical (including isotopic), sedimentary and biotic circumstances through the time intervals during which life crises occurred. These events affected terrestrial, lacustrine and estuarine ecosystems, locally and globally, but have affected continental shelf ecosystems and even deep ocean ecosystems. The pattern of these events is the backdrop against which modelling the pattern of future environmental change needs to be evaluated.
