The Tethys Ocean was an ocean that existed between the continents of Gondwana and Laurasia before the opening of the Atlantic Ocean.
The Tethys Sea was a shallow inland body of water that existed between Laurasia and Gondwana, the geological ancestor of the modern Black, Caspian and Aral Seas.
Paleontologists find the Tethys Ocean particularly important because much of the world's sea shelves were found around its margins for such an extensive period of time; Marine, marsh-dwelling, and estuarian fossils from these shelves are of considerable interest to them.

 Ocean - Wikipedia, the free encyclopedia
Ocean (from Okeanos, a Greek god of sea and water; Greek ωκεανός) covers almost three quarters (71%) of the surface of the Earth, and nearly half of the world's marine waters are over 3000 m deep.
Ocean currents greatly affect Earth's climate by transferring warm or cold air and precipitation to coastal regions, where they may be carried inland by winds.

The Alps arose as a result of the pressure exerted on sediments of the Tethys Ocean basin as its Mesozoic and early Cenozoic strata were pushed against the stable Eurasian landmass by the northward-moving African landmass.
As the Tethys Ocean basin continued to widen and deepen, the elements of weathering were always at work on the surrounding landmasses.
During the approximately 100 million years of open ocean, the rivers on the surrounding landmasses transported layers of mud, sand and gravel into the depths of the Tethys Ocean and formed compacted sediment layers several thousand meters in thickness.

The Tethys Sea is a shallow inland body of water that existed between Laurasia and Gondwana, the geological ancestor of the modern Mediterranean, Black, Caspian and Aral Seas.
The theory that the Tethys Sea existed was first proposed in 1893 by Eduard Suess, who used fossil records from the Alps and Africa.
As that part of the Tethys Ocean disappeared under Cimmeria, the relatively shallow area in the western end of the Tethys Ocean opened onto the growing Atlantic Ocean, forming the Tethys Sea (or 'Tethys Seaway').

Behind this new micro-continent the rift formed a new ocean, the Tethys Ocean.
As the Tethys Ocean widened, it pushed the Cimmeria and the floor of the Proto-Tethys Ocean northward towards Laurasia, the northeastern arm of Pangaea.
The Tethys rift eventually extended westward to split Pangaea in two, and the growing Atlantic Ocean separated the northern supercontinent of Laurasia from the southern supercontinent Gondwana.

This was accompanied by the gradual concentration of crustal shortening to the Western Alps, the Apenninen-Calabrian Arc, the southern Carpathian, and the Hellenic-Taurid Arc.
Changes in the ocean volume may have been induced by changes in the ocean ridge geometry due to acceleration or deceleration of the spreading rates, by uplift and subsidence of intraoceanic plateaux, or by the desiccation and flooding of restricted basins (Pitman, 1978; Donovan and Jones, 1979; Pitman and Golovchenko, 1983; Hallam, 1984; Kominz, 1984).

The northern continental strip of the CC comprised the north Tibetan (or Qiantang) block in the west and the north China block in the east.
The northward progression of the CC lead to the subduction of the Palaeo-Tethys Ocean along the southern margin of the Tarim block and to the formation of the Neo-Tethys Ocean between the CC and the Gondwana margin (Sengör, 1984).
The closure of the Palaeo-Tethys Ocean and the suturation of the CC occurred between Middle Triassic and Early-Middle Cretaceous (Sengör, 1984; Van der Voo et al., 1999; Zanchi et al., 2000).

A large ocean that originated between eastern Gondwana, Siberia, Kazakhstan, and Baltica in the Ordovician and finally closed in the Jurassic; replaced by the Tethys Ocean as eastern Pangea was assembled.
A small ocean that existed from the Triassic to the Jurassic; as Pangea was split into Gondwana and Laurasia in the Jurassic, an arm developed westward called the Tethys Seaway or Tethys Sea.

The Tethys was named in 1893 by the Austrian geologist Eduard Suess after the Titan Tethys, the daughter of Uranus and Gaia, and the sister and consort of Oceanus, the ancient Greek god of the ocean.
The Tethys Sea also expanded westward, splitting Pangaea into the supercontinents of Gondwana (in the South) and Laurasia (in the North).
By Late Triassic and Jurassic times, the Tethys extended a long, shallow arm through what is now Central Asia and Southern Europe, known as the Tethys Seaway (yet a third "Tethys").

The Tethys was a North-Northeast trending ocean that was bound by the European/Iberian margin to the west and the Adriatic promontory of Africa to east.
This ocean began closing during the Cretaceous as Africa moved towards the northeast and the opening Atlantic pushed Southern Europe to the east.
The spreading of Tethys, which occured during the middle and upper Jurassic, was parallel to the original Triassic rifts.

 A Depositional Model   (Site not responding. Last check: 2007-10-20)
Examination of the paleogeographic position of the Early Cretaceous Tethys Ocean shows that it is situated between two distinct climate regimes (see Figure 13).
Schmidt and Mysak (1996) were able to show that depending on salinity and temperature of the polar waters, the ocean can be in a metastable state, which neither favors polar nor tropical deepwater formation.
Thus we propose that the concept of an ``undecided ocean'' (with respect to deepwater formation) susceptible to external forcing is a fruitful concept for the Early Cretaceous too.

 Velikovskian Tectonics and Pangaea
This is a truly incredible statement, given that the Tethys Ocean was proposed in 1893 by Suess [2], years before Wegener's proposal of "continental drift", and many decades before modern plate tectonics refined the nature of continent movement.
The point of this is that there is evidence for Tethys Ocean beyond continent geometry, and you and Rose have ignored it.
Another point raised by Rose (p.9) is the "problem" of the speed at which India crossed the Tethys Ocean.

By 1857 he was a professor of geology at the University of Vienna, and from there he gradually developed views on the connection between Africa and Europe; eventually he came to the conclusion that the Alps to the north were once at the bottom of an ocean, of which the Mediterranean was a remnant.
While not quite correct (mostly because plate tectonics had not yet been discovered -- he used the earlier geosyncline theory), this is close enough to the truth that he is credited with discovering the Tethys Ocean, which he named in 1893.
Again, this is not quite correct: Suess believed that the oceans flooded the spaces currently between those lands, when in fact the lands drifted apart.
