Fossils, frogs, floating islands and expanding Earth in changing-radius cartography A comment to a discussion on Journal of Biogeography

G. Scalera


In this short note I have tried to make clear the issues surrounding a recent discussion on changing-radius paleobiogeographical
problems of the Pacific Ocean biotic distribution. It is stressed that such an important discussion
cannot be developed in the absence of proper cartographic methods that must necessarily introduce an increasing
radius parameter, highlighting the effects of a changing curvature in the continental/oceanic plates in their movements
from a globe of a given radius to a new position on a globe of different radius. Many other aspects of paleogeography,
paleomagnetism, paleoclimate can be faced in a new and more open-mind philosophy and considered
in a legitimate additional degree of freedom: globe size increasing. The new increasing-radius Cartography can become
of fundamental importance for the advancement of science not only of Earth sciences.
