Zealandia

Mostly submerged continental crust area in Oceania

Zealandia (pronounced), also known as Te Riu-a-Māui (Māori) or Tasmantis (from the Tasman Sea), is an almost entirely submerged mass of continental crust in Oceania that subsided after breaking away from Gondwana 83–79 million years ago. It has been described variously as a submerged continent, continental fragment, and microcontinent. The name and concept for Zealandia was proposed by Bruce Luyendyk in 1995, and satellite imagery shows it to be almost the size of Australia.
