Answer:
During the Paleozoic era, not all continents were located at polar latitudes, so not all of them experienced glaciation. The modern continents that do not show evidence of glaciation during the Paleozoic era include Africa, South America, Australia, and Antarctica (which was located near the equator at the time).
Some of the countries located away from polar latitudes today that were once placed near the southern polar region include South Africa, Australia, and Argentina. These countries were part of the supercontinent Gondwana, which was located near the South Pole during the Paleozoic era. As a result, they were covered in ice and experienced glaciation during this time.
