Abstract: The development of palaeobiology has involved 4 stages:palaeomorphology, palaeoecology, palaeobiogeography and study of palaeobiomigration.The last stage is an inevitable outcome of the evolution of palaeobiology at the present time.J.S.Lee, founder of Geomechanics in China, had noted biomigration as early as 1920s, and applied it to study the rules governing marine transgression.In 1960s he further emphasized the significance of study of biomigration.It is thought that the study of palaeobiomigration may provide some important informations for the study of crustal movement as well as palaeobiology.
