The great dinosaur bone beds of the American and Canadian West are world famous and have yielded spectacular fossil finds. But the eastern United States and maritime Canada, where dinosaurs also roamed in great numbers, have been equally important to the study of these extraordinary creatures. Some dinosaur fossils have come from the bog iron and clay pits of Maryland and New Jersey, while others have been discovered in the riverbanks of North and South Carolina. Dinosaur footprint sites have been found from central Virginia to the Bay of Fundy in Nova Scotia.

This volume presents the work of researchers at many sites spanning the East African Pliocene. The authors take a broad approach that seeks to compare paleoenvironmental and paleoecological patterns across localities and among various taxonomic groups. This volume aims to synthesize large amounts of faunal data, and to present the evolution of East African vertebrates in the context of environmental and climatic changes during the Pliocene.

About four hundred million years ago earthquake activity and possibly major storms caused sudden movements of large quantities of muddy sediment along the seafloor. Animal communities in the path of these sediment-laden flows were instantly engulfed, the inhabitants "frozen" in the last moment of their lives. Amazingly, many of the creatures lost in this ancient catastrophe were almost perfectly preserved through the eons, fossilized in a thick series of muds now known as the Hunsruck Slate west of the Rhine Valley in western Germany. Excavations there have yielded the most diverse and...

This book focuses on the first vertebrates to conquer land and their long journey to become fully independent from the water. It traces the origin of tetrapod features and tries to explain how and why they transformed into organs that permit life on land. Although the major frame of the topic lies in the past 370 million years and necessarily deals with many fossils, it is far from restricted to paleontology. The aim is to achieve a comprehensive picture of amphibian evolution. It focuses on major questions in current paleobiology: how diverse were the early tetrapods? In which...
