Fossil Footprints Of Western North America

Offering the most comprehensive and up-to-date review of fossil footprints, for both dinosaurs and other vertebrates, in the western United States, Dinosaur Tracks covers the fossil record from the Paleozoic through the Cenozoic era. A series of illustrations depict dinosaurs in the their natural habitat, and an appendix lists museums and other major repositories of tracks and replicas, and gives details on tracksites open to the public. Includes annotated references and detailed descriptions of important specimens, describing how these trackways can help interpret behavior.

The long and distinguished tradition of tracking dinosaurs and other extinct animals in Europe dates back to the 1830s. Yet this venerable tradition of scientific activity cannot compare in magnitude and scope with the unprecedented spate of discovery and documentation of the last few years. Now, following on the heels of his Dinosaur Tracks and Other Fossil Footprints of the Western United States, Martin Lockley teams up with Christian Meyer to present an up to date synthesis of the recent findings in the field of European fossil footprints. Drawing extensively on their own research results from studies in Britain, Switzerland, Portugal, Spain, and elsewhere, the authors create a dynamic picture of mammal, reptile, bird, and amphibian "track-makers" throughout more than 300 million years of vertebrate evolution, placed in the context of Europe's changing ancient environments. Beginning with an introduction to tracking and a history of the European tracking tradition, Dinosaur Tracks and Other Fossil Footprints of Europe then charts a broad path of evolutionary proliferation from the proto-dinosaurs of the Early Triassic period to the dinosaurs' decline and disappearance in the Upper Cretaceous. The survey continues into the age of mammals and birds, ending with the cave art of our Paleolithic ancestors.

How can the tracks of dinosaurs best be interpreted and used to reconstruct them? In many Mesozoic sedimentary rock formations, fossilized footprints of bipedal, three-toed (tridactyl) dinosaurs are preserved in huge numbers, often with few or no skeletons. Such tracks sometimes provide the only clues to the former presence of dinosaurs, but their interpretation can be challenging: How different in size and shape can footprints be and yet have been made by the same kind of dinosaur? How similar can they be and yet have been made by different kinds of dinosaurs? To what extent can tridactyl dinosaur footprints serve as proxies for the biodiversity of their makers? Profusely illustrated and meticulously researched, Noah's Ravens quantitatively explores a variety of approaches to interpreting the tracks, carefully examining within-species and across-species variability in foot and footprint shape in nonavian dinosaurs and their close living relatives. The results help decipher one of the world's most important assemblages of fossil dinosaur tracks, found in sedimentary rocks deposited in ancient rift valleys of eastern North America. Those often beautifully preserved tracks were among the first studied by paleontologists, and they were initially interpreted as having been made by big birds—one of which was jokingly identified as Noah's legendary raven.

This look at the field of ichnology is “an excellent compendium and a timely piece on a rapidly expanding and changing area of research” (Quarterly Review of Biology). The latest advances in dinosaur ichnology are showcased in this comprehensive and timely volume, in which leading researchers and research groups cover the most essential topics in the study of dinosaur tracks. Some assess and demonstrate state-of-the-art approaches and techniques, such as experimental ichnology, photogrammetry, biplanar X-rays, and a numerical scale for quantifying the quality of track preservation. The high diversity of these up-to-date studies underlines that dinosaur ichnological research is a vibrant field, that important discoveries are continuously made, and that new methods are being developed, applied, and refined. This indispensable volume unequivocally demonstrates that ichnology has an important contribution to make toward a better understanding of dinosaur paleobiology. Tracks and trackways are one of the best sources of evidence to understand and reconstruct the daily life of dinosaurs. They are windows on past lives, dynamic structures produced by living, breathing, moving animals now long extinct, and they are every bit as exciting and captivating as the skeletons of their makers.

Comprehensive in detail and worldwide in scope, Chirotheres is the definitive compendium of what is known about the five-toed footprints of Triassic archosaurs, ancestors of the crocodiles. Sandstone slabs with extensive trackways have been known for almost two centuries and are highlights in museum exhibits around the globe. These trackways provide direct insight into the locomotion and behavior of the fascinating reptiles that made these tracks, and, together with known skeletons, they allow a richer reconstruction of chirothere lifestyle than is possible from bones alone. Written by expert researchers in the fields of vertebrate ichnology, vertebrate paleontology, and scientific illustration, Chirotheres explores the various facets of chirothere research including the history of their study, footprint formation and preservation, the bone record, the environment and lifestyle of chirotheres, and finally, their disappearance at the end of the Triassic. Chirotheres also features a global compendium of track collections with chirothere material, including specimen numbers, detailed phylogenetic definitions of track makers, and extensive measurements from key chirothere tracks and trackways. It represents an invaluable resource of anyone interested in these ancient animals.
