Answer :
Answer;
They fused into Pangaea
By the close of the paleozoic era all the continents fused into Pangaea.
Explanation;
Paleozoic era is the era of "ancient life".
During the early Paleozoic era, South America, Africa, Australia, Antarctica, India, and perhaps China comprised the vast southern continent of Gondwana.
At the beginning of this period, all continents joined together to form the supercontinent Pangaea, which was encircled by one ocean called Panthalassa.
The event that took place during the last period of the Paleozoic era was that all the continents that were present at that time joined together to form a new big supercontinent.
This supercontinent was named as Pangaea.
This was encircled by a large ocean body called as Panthalassa. The land mass at that time was very dry with harsh seasons as it was not regulated by the water bodies.
