Two of the previous supercontinents, which formed 200 million years ago (Pangaea) and 800 million years ago (Rodinia). The Americas and Asia may fuse together to form a new supercontinent, “Amasia.”

What are the two supercontinents?
These all-in-one supercontinents include Columbia (also known as Nuna), Rodinia, Pannotia and Pangaea (or Pangea). Gondwana was half of the Pangaea supercontinent, along with a northern supercontinent known as Laurasia.
Which is older Pangea or Gondwana?
Gondwana (550-150 mya)
It assembled hundreds of millions of years before Pangea. Gondwana formed a large part of the Pangean supercontinent and even persisted for tens of millions of years after Pangea broke up.
What is Rodinia supercontinent?
Rodinia (from the Russian родина, rodina, meaning “motherland, birthplace”) was a Neoproterozoic supercontinent that assembled 1.1–0.9 billion years ago and broke up 750–633 million years ago. Valentine & Moores 1970 were probably the first to recognise a Precambrian supercontinent, which they named ‘Pangaea I’.
Which supercontinent was before Rodinia?
Rodinia is thought to have assembled at 1.1 billion years. Before that at 1.8 billion came the possible assembly of a supercontinent known as Nuna or Columbia, and at 2.5 billion the assembly of Kenorland.

What was 300 million years ago?
Characteristic of the Carboniferous period (from about 360 million to 300 million years ago) were its dense and swampy forests, which gave rise to large deposits of peat. Over the eons the peat transformed into rich coal stores in Western Europe and North America.

Reptiles arose about 300 million years ago, and they replaced amphibians as the dominant land-dwelling animal following the Permian Extinction.
Who discovered Pangea?
In 1912 Alfred Wegener (1880-1930) noticed the same thing and proposed that the continents were once compressed into a single protocontinent which he called Pangaea (meaning “all lands”), and over time they have drifted apart into their current distribution.
What is Pangea and Gondwana?
Pangea, the most recent supercontinent, attained its condition of maximum packing at ~250 Ma. At this time, it consisted of a northern part, Laurasia, and a southern part, Gondwana. Gondwana contained the southern continents—South America, Africa, India, Madagascar, Australia, and Antarctica.

The last supercontinent, Pangea, formed around 310 million years ago, and started breaking up around 180 million years ago. It has been suggested that the next supercontinent will form in 200-250 million years, so we are currently about halfway through the scattered phase of the current supercontinent cycle.
