This may well be an indication that earth was spinning on an entirely different axis.
Tectonic plate movement. Continents don’t stay put; they wander around.
The poles are always shifting. Usually just a few miles per year, and not in a predictable manner. Now the eco-freaks claim it is because of man made global warming.

Well, both the high northern and high southern latitudes have fossilized tropical flora and fauna, but as far as I know there is no evidence of glacial activity around the equatorial region, so it doesn’t look like a result of spinning on a different axis. It looks more like the entire planet was tropical or semi-tropical at some point.
