Abstract

STUDENTS of fossils are interested in Wegener's theory that the continents are floating on a heavier layer of the earth's crust which, sometimes at least, becomes plastic and allows them to move through different longitudes and latitudes. If there has been such movement during geological time, this may clearly explain the changes of climate in many areas to which fossils bear witness. It affords a possible reason for the occurrence of plants and animals of temperate or even subtropical habit among the fossils found in the present arctic and antarctic regions. It also perhaps shows why the land and fresh-water life of the coal period throughout the northern hemisphere was so remarkably uniform.
