what ocean existed before pangea formed?

Question

i know the answer, does anyone else know??

Answer 1

Late Proterozoic: PanAfrican and Panthalassa oceans
Cambrian: the Iapatus between Laurentia and Baltica
Ordovician: Iapetus, Paleo-tethys, Panthalassa oceans
Silurian: Iapetus, Rheic, and Paleo-Tethys Oceans between the continents and Panthalassa around the outside
Devonian-Carboniferous: the three inner oceans closing up between the continents, and Paleotethys reconfigures. Panthalassa just gets bigger.
Permian--Pangea time--Rheic and Iapetus gone. Paleotethys reconfigured, and little Tethys sea floor forming north of Australia. Panthalassa ocean really big.

Answer 2

There was three oceans when Pangaea formed. Panthalassic Ocean, Paleo-Tethys Ocean, and Tethys Ocean. Is that what you were looking for? The oceans around Pannotia (the supercontinent before Pangaea) were the Panthalassic Ocean and Panafrican Ocean. Honestly the stuff I deal with is a lot older working from Rodinia.
