“Zealandia (/ziːˈlændiə/), also known as the New Zealand continent or Tasmantis,[2] is an almost entirely submerged mass of continental crust that sank after breaking away from Australia 60–85 million years ago, having separated from Antarctica between 85 and 130 million years ago.[3][citation needed] It has variously been described as a continental fragment, a microcontinent, a submerged continent, and a continent.[4] The name and concept for Zealandia was proposed by Bruce Luyendyk in 1995.[5] Zealandia’s status as a continent is not universally accepted, but New Zealand geologist Nick Mortimer has commented that “if it wasn’t for the ocean” it would have been recognized as such long ago.[6] ”
