The Marsupials would be extinct as they wont be able to migrate to South America and Australia.
Explanation:
If the plate tectonics would be in a position as they are in today then the marsupials population that is found today in Australia and other countries would not have been possible as the plate tectonics would not allow them to migrate to these places.
Even if they would migrate to another pace they would not survive as these creatures don't know how to travel longer distances and would eventually die of starvation.
