Panthalassa means "all seas." It was the all the world's oceans that surrounded Pangaea before the continental drift occurred in the triassic period.
The name "Panthalassa" comes from the Greek words "pan" meaning "all" and "thalassa" meaning "sea." It was used to refer to the global ocean that surrounded the supercontinent Pangaea during the late Paleozoic and Mesozoic eras.
Wegener chose to describe Panthalassa as a single, vast ocean because he believed it helped support his theory of continental drift. By proposing the existence of one supercontinent surrounded by a single ocean, Wegener sought to explain how the continents could have once been joined together before moving apart over geological time. This concept of a unified Panthalassa ocean helped provide a framework for his continental drift theory.
The supercontinent that existed 250 million years ago is called Pangaea, and the ocean that surrounded it is known as Panthalassa.
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.
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.

Pangaea was a supercontinent that existed around 335 million years ago and later split into the continents we have today. Panthalassa was the vast ocean surrounding Pangaea.
Alfred Wegener, a German meteorologist and geophysicist, first proposed the theory of Pangaea and Panthalassa in the early 20th century. He suggested that the continents were once joined together in a supercontinent called Pangaea, surrounded by a single large ocean known as Panthalassa.
This massive body of water was called Panthalassa.
That would be Alfred Wegener
'Panthalassa' was the great sea that surrounded Pangea.
Panthalassa was the vast global ocean that surrounded the supercontinent Pangaea during the late Paleozoic and Mesozoic eras. It covered about 70% of Earth's surface at the time and played a key role in shaping the planet's climate and geography.
The name "Panthalassa" comes from the Greek words "pan" meaning "all" and "thalassa" meaning "sea." It was used to refer to the global ocean that surrounded the supercontinent Pangaea during the late Paleozoic and Mesozoic eras.
During the time of the supercontinent Pangaea, the ocean known as Panthalassa surrounded Pangaea. Panthalassa was a vast ocean that covered most of the Earth's surface. As Pangaea broke apart, this single ocean eventually split into the modern oceans we have today.
