Wow, that's incredible.
1. The Proterozoic era was long!
2. Amazing how recent the current configuration is.
3. I always assumed that dinosaurs were walking around Earth in its current configuration. Fossils are found in Canada, China etc, you assume it is the same as current day Canada and China, but it's just where that rock happens to be now.
4. Expect a lot more movement in future.
5. Did a load of water disappear or did the (now smaller) oceans just get deeper?

No. Supposedly there is the same amount of water on Earth there's always been. So the oceans got deeper. Or, with volcanic activity, the land masses got higher and wider.

I imagine you are correct. I've never heard that question before. But I've heard from scientific sources, there is the same amount of water on Earth as there's always been. And I've heard prehistoric oceans described as "shallow seas". The land was created by volcanic activity. And plates pushing into each other buckling the mantle. You probably already know, that's how mountain ranges are formed. Sea level also is greatly affected by global temperatures. Prehistorically, the Earth was a lot warmer. That means less ice, less frozen water, deeper oceans and seas.
