That is excellent.
you can have some fun with this inter-active gravity map:

and no, down there hasn’t always been the coldest part of the globe, there are fossil forests, lots of fossil plesiosaurs, fresh water lakes under the ice...and rivers.
“Wonder how they track where a piece of the crust is xxx years ago?”
By analyzing the rocks.
There is a part of the Appalachian Mountains that mysteriously appears in Argentina. THAT ONE really intrigues me!
We are, after all, talking about spans of years in tens-of-millions or hundreds-of-millions. That is a long, long time and the earth’s crust is moving those tectonic plates around constantly though slowly.
I keep reminding myself that God created the Universe. That includes all the scientific laws that operate within it.

The Paleozoic is bracketed by two of the most important events in the history of animal life. At its beginning, multicelled animals underwent a dramatic "explosion" in diversity, and almost all living animal phyla appeared within a few millions of years. At the other end of the Paleozoic, the largest mass extinction in history wiped out approximately 90% of all marine animal species. The causes of both these events are still not fully understood and the subject of much research and controversy. Roughly halfway in between, animals, fungi, and plants alike colonized the land, the insects took to the air, and the limestone shown in this picture was deposited near Burlington, Missouri.
The Paleozoic took up over half of the Phanerozoic, approximately 300 million years. During the Paleozoic there were six major continental land masses; each of these consisted of different parts of the modern continents. For instance, at the beginning of the Paleozoic, today's western coast of North America ran east-west along the equator, while Africa was at the South Pole.

epiphany?
No subduction zones?
...how do we get earthquakes?
My head hurts...
In 1888 Ivan Osipovich Yarkovsky suggested that some sort of aether is absorbed within the earth and transformed into new chemical elements, forcing the celestial bodies to expand. This was connected with his mechanical explanation of gravitation. [23] Also the theses of Ott Christoph Hilgenberg (1933, 1974) [24] [25] and Nikola Tesla [26] were based on absorption and transformation of aether-energy into normal matter.
Well we know there are particles flying around ,...coming out of the stars....

Pangaea did not start to break up until about 200 million years ago,
