Museum collections were used to document the worldwide Pliocene and Pleistocene fossil record of 59 species that now occur on the Atlantic continental margin of North America. Tabulation of these data indicates that benthic foraminifera evolve at all latitudes and in all parts of the world ocean rather than from some center or centers of origin. Dispersal in geologic time is very rapid.
