Panthalassa means "all seas." It was the all the world's oceans that surrounded Pangaea before the continental drift occurred in the triassic period.
Thalassa is the Greek primeval goddess of the sea.
The oldest ocean, geologically, is the Panthalassa Ocean which was around 220 million years ago in the Triassic era. It encompassed the whole Earth except the land mass Pangea. See related link for more information.
The supercontinent that existed several million years ago is called Pangea. It combined all of today's continents into one supercontinent, mostly in the Southern Hemisphere. It was surrounded by a super ocean, Panthalassa, and started to break up 175 million years ago.
Alfred Wegener was a German weatherman (more specifically, a meteorologist at the University of Marburg) who wrote a book, "Die Entstehung der Kontinente und Ozeane," or "The Origin of Continents and Oceans" on the idea of Pangaea. This book came out in 1912 in Germany and 1915 in the USA, despite the First World War going on. Although Alfred Wegener is often recognized as being the originator of the idea of Pangaea, the American geologist Frank Bursley Taylor started theorizing about Pangaea in 1908. He did not, however, really go anywhere with this idea and didn't come up with the name "Pangaea". Alfred Wegener did.
Pangaea or Pangea (derived from Παγγαία, Greek meaning 'all earth') is the supercontinent that existed during the Paleozoic and Mesozoic eras about 250 million years ago, before each of the component continents were separated into their current configuration.http://en.wikipedia.org/wiki/Image:Pangaea_continents.pngPangaea is believed to have been a C-shaped landmass that spread across the equator. The body of water that was believed to have been enclosed within the resulting crescent has been named the Tethys Sea. Owing to Pangaea's massive size, the inland regions appear to have been very dry, due to the lack of precipitation. The large supercontinent would potentially have allowed terrestrial animals to migrate freely all the way from the South Pole to the North Pole. The vast ocean that once surrounded the supercontinent of Pangaea has been named Panthalassa. Pangaea is believed to have broken up about 180 million years ago (mya) in the Jurassic Period, first into two supercontinents (Gondwana to the south and Laurasia to the north), thereafter into the continents as we understand them today.
The first ocean on Earth is believed to have been the "global ocean" that emerged around 3.8 billion years ago, called the "Panthalassic Ocean." This ocean eventually transformed into the modern-day Pacific Ocean through continental drift and plate tectonics.

Thalassa is the Greek primeval goddess of the sea.
'Panthalassa' was the great sea that surrounded Pangea.
That would be Alfred Wegener
This massive body of water was called Panthalassa.
The single enormous ocean which surrounded Pangaea is known as Panthalassa.
The one major ocean in the time of Pangaea has been termed as Panthalassa.
