The east and west hemispheres are artificial. The prime meridian through Greenwich was globally agreed upon as being 0 longitude.
So, the question is meaningless, especially in consideration of continental movement.
There is no middle of the world in the east and west sense, as there is with north and south, where the division is made by the rotation of the earth, making the Equator and the poles real markers.

Neither. In order to have an Eastern Hemisphere and a Western Hemisphere you have to have two sets of continents. Pangaea was the last time the super-continent was assembled, therefore it was "The Hemisphere".

to build upon what he said, if you take the prime meridian place back in time on a map of the earth, and watch the continents move, pangea (or pangaea) is not located specifically in either, it is spead across both of them because it stradles the prime meridian much like african and europe do today.
