Book Description
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.

Book Description
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.

Book Description
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.

Book Description
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.

Book Description
Dinosaur Tracks from Brazil is the first full-length study of dinosaurs in Brazil. Some 500 dinosaur trackways from the Cretaceous period still remain in the Rio do Peixe basins of Brazil, making it one of the largest trackways in the world. Veteran paleontologists Giuseppe Leonardi and Ismar de Souza Carvalho painstakingly document and analyze each track found at 37 individual sites and at approximately 96 stratigraphic levels. Richly illustrated and containing a wealth of data, Leonardi and de Souza Carvalho brilliantly reconstruct the taxonomic groups of the dinosaurs from the area and show how they moved across the alluvial fans, meandering rivers, and shallow lakes of ancient Gondwana. Dinosaur Tracks from Brazil is essential reading for paleontologists.
