in the late jurassic, gondwanaland begins to break apart creating western gondwana, which was composed of the south american and african continental land masses, and eastern gondwana. the eastern gondwanian continent was made madagascar, greater india, antarctica, and australia. during this period of time australia shared its southern margin with antarctica and the western margin (now the exmouth plateau) with greater india. the formation of the exmouth's northern margin, the argo abyssal plain, was not initiated until 155 million years ago when australia broke apart from a continental fragment of the burma plate that's present location is argued to be subsumed under asia. it wasn't until 20 million years later that the greater indian land mass broke from western australia, forming the central and southern margins of the exmouth plateau now known as the gascoyne and cuvier abyssal plains. as australia continued to diverge away from the antarctic land mass, it migrated in a northeastern direction and rotated counterclockwise to it present location, leaving the exmouth plateau along the continent's western margin.

pangea was created by the continent of gondwanaland and the continent of laurussia. during the carboniferous period the two continents came together to form the supercontinent of pangea. the mountain building events that happened at this time created the appalachian mountains and the variscan belt of central europe. however, not all landmasses on earth had attached themselves onto pangea. it took until the late permian until the siberian land mass collided with pangea. the only land mass to not be a part of pangea were the former north and south china plates, they created a much smaller land mass in the ocean. there was a massive ocean that encompassed the world called panthalassa, because most of the continental crust was sutured together into one giant continent there was a giant ocean to match.
