Zealandia (pronounced /ziːˈlændiə/), also known as Te Riu-a-Māui (Māori)[2] or Tasmantis (from Tasman Sea),[3][4] is an almost entirely submerged mass of continental crust in Oceania that subsided after breaking away from Gondwana 83–79 million years ago.[5] It has been described variously as a submerged continent, continental fragment, and microcontinent.[6] The name and concept for Zealandia was proposed by Bruce Luyendyk in 1995,[7] and satellite imagery shows it to be almost the size of Australia.[8] A 2021 study suggests Zealandia is over a billion years old, about twice as old as geologists previously thought.[9][10]
Homicide: Life on the Streets apparently had something similar in S3 E16.
I’d link a video, but the producers of the series has apparently done a lot of IP trolling on YouTube, and as shitty as YouTube is, DailyMotion is shittier.
