Hi, Howard.
That’s pretty much the case. We know now there have been quite a few Pangaeas as the core continents bump together and break apart. Working out how they fitted together is not unlike an old, eroded aircrash reconstruction without all the pieces.

Remember continents are just the lightweight cold skin atop the slowly percolating and circulating mantle, that’s the engine of the large-scale dynamics.
