The
Proto-Tethys Ocean was an ancient
ocean that existed from the latest
Ediacaran to the
Carboniferous. It was an ocean predecessor of the later
Paleo-Tethys Ocean. The ocean formed when
Pannotia disintegrated, Proto-Laurasia (Laurentia, Baltica, and Siberia) rifted away from a supercontinent that will become
Gondwana, it formed between them. However, before the start of the Paleozoic Era,
Proto-Laurasia, separated into three separate continents,
Laurentia,
Baltica, and
Siberia, opening the
Iapetus Ocean (an ocean between Baltica and Laurentia), and
Khanty Ocean (an ocean between Baltica and Siberia). The ocean was bordered by
Panthalassic Ocean to the north, separating it from Panthalassa by
island arcs and
Kazakhstania. Proto-Tethys expanded during Cambrian. The ocean was at its widest during the Late
Ordovician to Middle
Silurian. The ocean was situated between the
Siberia to the west, and
Gondwana to the east. The ocean began to shrink during the Late Silurian, when
North China, and
South China moved away from Gondwana and headed north, and during Late
Devonian. The microcontinent of
Kazakhstania collided with Siberia, shrinking the ocean further. The ocean closed when the North China collided with Siberia-Kazakstania continent in the
Carboniferous, while the Paleo-Tethys Ocean expanded.

Proto-Laurasia ("first Laurasia") was an ancient supercontinent. It has been part of two major supercontinents - Rodinia, and Pannotia. In Rodinia, South China, Baltica, and Siberia were connected to Laurentia (North America) on the eastern side of the craton.
