Zealandia also known as the New Zealand continent or Tasmantis,  is a nearly submerged mass of continental crust that sank after breaking away from Australia 60–85 Ma (million years) ago, having separated from Antarctica between 85 and 130 Ma ago.[3] It has variously been described as a continental fragment, a microcontinent and a continent.[4] The name and concept for Zealandia were proposed by Bruce Luyendyk in 1995.


Australinea is a continent comprising mainland Australia, Tasmania, New Guinea, Seram, Timor, and neighbouring islands.
