Originally published by Cambridge UP in 1991, this book is a translation of a unique Russian study of fossil plant distributions in the Jurassic and Cretaceous world. The core of the work is the description and assessment of floras of the USSR, China and Japan. Information on the floras of this extensive and productive area had hitherto been available only in scattered and sometimes obscure Russian journals. Vakhrameev also summarises the more familiar Western work and divides the continents into regions and provinces illustrating the palaeolatitudinal climatic arrangement of floras. The work deals first with megafossil plants and with land plant palynomorphs. The time covered from 200 to 65 million years ago ranges both before and immediately after the main angiosperm radiation from about 130 to 100 million years ago. Vakhrameev's work represents a vast source of data, which will be of interest to any student of Mesozoic seed plants.
