Animal-Sediment Relations

The purpose of this book is to compile the published knowledge on fossil rodents from North America and present it in a way that is accessible to paleontologists and mammalogists interested in evolutionary studies of ro­ dents.Hence, this book is limited to the re cord of Tertiary rodents of North America. Thus, it is not surprising that the fossil record of this order is extensive and fossil material of rodents from the Tertiary is known from all continents except Antarctica and Australia.

The book begins with a description of the systematic position of the Ammonoidea within the Cephalopoda, providing the phylogenetic framework for the rest of the book. With its diverse viewpoints and new material, this resource will benefit researchers and graduate students in paleontology, marine biology, and evolutionary biology. Following discussions include soft- and hard-part morphology of ammonoids, rate of growth and ontogeny, and taphonomy and ecology..

Ammonoid Paleobiology Closing chapters explore the distribution of ammonoids in time and space as well as their extinction at the end of the Cretaceous.. The book begins with a description of the systematic position of the Ammonoidea within the Cephalopoda, providing the phylogenetic framework for the rest of the book.

Contributions to this volume detail paleontologic research in Manonga Valley, and shed important light on the evolutionary development of eastern Africa. Chapters provide novel insights into the taxonomy, paleobiology, ecology, and zoogeographic relationships of African faunas, as well as lay the foundation for future geological, paleontological, and paleoecological studies in this important area. Neogene Paleontology of the Manonga Valley, Tanzania.The book concludes with a discussion of the importance of investigations on broader geographical sites, including the Manonga Valley, for human evolution research.

Advances in plate tectonics form the basis for a modern synthesis and, in the broadest terms, dictate the framework within which the past and present distributions of organisms must be interpreted. Geology had made remarkable progress toward an understanding of the phys­ ical history of the Caribbean Basin for the last 100 million years or so.
