If Pangea existed ~225 million years ago (as we understand it) and the continents began drifting apart, is there any observable measurement of the continents drifting/merging back together?

Pangaea wasn't the original continent, it was just the most recent supercontinent. There have been lots of cycles of continents breaking up and coming back together - India (with Madagascar for the first bit) was an island continent like Australia from about 140 million years ago until it collided with Asia some time around 50 million years ago.

Using GPS (and other things) we can see how the modern tectonic plates are moving, and from present motions and our knowledge of what drives plates we can make guesses at how the continents might be configured in the future.
