1893E. Suess in Natural Sci. II. 186 We might..rather be induced to infer that in Prepalæozoic times there may have existed a universal hydrosphere or panthalassa covering the whole of the planet. 1924J. G. A. Skerl tr. Wegener's Orig. Continents & Oceans x. 149 It is..not improbable that in the most ancient ‘pre-geological times’ the film of sial..could then have been..only about 30 km. thick, and have been covered with a ‘Panthalassa’..which probably left exposed only small proportions, or none at all, of the earth's surface. 1937A. L. Du Toit Our Wandering Continents x. 210 The Drift Hypothesis..has to view the great geosynclinal seaways of earlier geological history as branches, albeit important ones, of a universal ocean or ‘Panthalassa’, which was transformed into the present oceans through the horizontal drifting of the crustal blocks. 1970R.
