I was looking up a different phenomena that I hear on a show which I
never heard of before, that in the deep history of the earth, before the Cambian period, the earth physically flipped north/south


I didn't find anything but I did find about a mear 88 million years ago
the planet rotated in a non-normative way nearly 12 degrees back for
forth... like if you push a top?

The gradual change of the rotation of Earth and the revolution of Moon
may have some consequences to geology and paleontology but nothing
important.
