The last supercontinent, Pangaea, formed about 300 million years ago.
The previous supercontinent, Pannotia or Greater Gondwanaland, formed about 600 million years ago, and its dispersal formed the fragments that ultimately collided to form Pangaea.
Rodinia, existed ~1.1 billion to ~750 million years ago - a mere 150 million years before Gondwanaland.
The supercontinent before this was Columbia: ~1.8 to 1.5 billion years ago.
And before this was Kenorland: ~2.7 to ~2.1 billion years ago.
Ur existed ~3 billion years ago and Vaalbara ~3.6 to ~2.8 billion years ago.

First there was this huge super-continent named Rodinia, then it broke into two major parts: Gondwana and Protho-Laurasia, after this they began breaking and colliding with each other until Gondwana and Laurasia, not Protho anymore, formed and then this two collided a last time to form Pangaea...
Search for Pangaea in wikipedia and you won't only know the 2 before of pangaea but also the whole collision and separation story...

Brooklyn and Staten Island. If you know the answers, why ask here? It's not a quiz show.
