Article: Larger Foraminifera and seas through time

The broad features of larger foraminifera1 distribution through their history from Late Palaeozoic times on are outlined on the appropriate Symposium Base Maps, and briefly discussed in the context of such maps. Major postulates in plate tectonics and continental drift theory, viz. the opening of the Atlantic Ocean and the flight of India and Australasia are considered in relation to evidence from this group of organisms.
