In the past 100 years, many dozens of extraordinary dinosaurs and other fossil amphibians, reptiles, birds and mammals have been found in the former Soviet Union. The Permo-Triassic of the Ural Mountains in particular have produced hundreds of superb specimens, and many of the dinosaurs from Mongolia are unique. Written by a group of Russian and Western paleontologists, this volume reveals a range of fossil faunas, in particular reptiles, that have been little known outside Russia. This is the first time that much of this large body of research has been introduced in English. Chapters contain accounts of the history of collecting, the relevant stratigraphy and geogical setting, and the major animal groups prepared by this auspicious collaboration of researchers. More than 300 illustrations and line drawings provide a clear, visual record. This volume will be of interest to graduate students and researchers in paleontology and zoology.
