The Pangaea theory postulates that millions of years ago, all the Earth's continents were joined together as a single landmass known as Pangaea. This supercontinent later fragmented and drifted apart to form the continents we see today. The theory is supported by geological evidence, such as matching rock formations and fossils on separate continents.
The single land mass is called Pangaea. It was the supercontinent that existed about 300 million years ago before breaking apart into the continents we know today.
Australia and Antarctica are the only continents located on their own, separate landmasses and are referred to as island continents because they do not touch any other continent. North and South America are located on a single landmass (America). Europe, Asia, and Africa are located on a single landmass (Afro-Eurasia).
The single landmass that once contained all of Earth's continents is called Pangaea. It existed during the late Paleozoic and early Mesozoic eras, before breaking apart into the continents we recognize today.
The continents that were part of Gondwana land are Australia, Antarctica and South America.
In the beginning all the continents of the Earth were joined together to form 'Pangaea' . This large piece of land was then divided into current continents . The Pangaea started to separate about 10 billion years ago .
I think you are referring to Pangaea. Pangaea was the gigantic single continent that broke into the continents we have today. See the Related Link below for the Wikipedia entry.
The inference is that both continents were once one single land-mass.

The first original land mass is called Pangaea. It was a supercontinent that existed about 335 million years ago, before breaking apart into the separate continents we have today.
When continents break apart into separate land masses, it is called continental drift or plate tectonics. This process is driven by the movement of the Earth's lithospheric plates.
