Following a brief review of some general considerations, the distributions in space and time of two exemplar sets of Cainozoic Ostracoda, one marine and the other dominantly freshwater but each containing about 150 species, are used to evaluate the alternatives of continental permanence or continental drift. Taxa are approached phenetically. Discontinuities and dispersal potentials provide appropriate scales of values. It is concluded that the evidence does not negate Drift Theory.
