Which of these is the most likely explanation for the existence of dicynodont fossils on modern-day Antarctica?

#Unit 11. Evolution and Behavior

  1. They arrived there aboard ʺraftsʺ of vegetation, and quickly adapted to the bitterly cold climate.

  2. Earthʹs polar regions were once so warm (especially immediately after the ʺsnowball Earth periodʺ) that reptiles and mammal-like reptiles flourished there.

  3. The landmass that is now the Antarctic continent was formerly located at a more-northerly position, and was also united to other landmasses.

  4. Dicynodonts originated on the island continent of Antarctica and went extinct as the continent migrated to its current position at the South Pole.
