The Permo-Triassic of the Ural Mountains of Russia have produced hundreds of superb specimens, and many of the dinosaurs from Mongolia are unique. This is the first compilation in any Western language of this large body of Russian research and the first time so much of this research, previously unexplored by the West, has been introduced in English. The Age of Dinosaurs in Russia and Mongolia is written by a unique mix of Russian and Western palaeontologists, and provides an entrée to a range of fossil faunas, in particular reptiles, that have been little known outside Russia. It will undoubtedly become a major reference work for all vertebrate palaeontologists.
