A journey to plumb the remote ocean depths has revealed that Earth does indeed have an eighth continent.

A nine-week voyage took scientists from around the world to drill and explore the seafloor off New Zealand and Australia. They found evidence of land-based fossils, revealing that the ancient landmass wasn't always buried beneath the waves.

"Zealandia, a sunken continent long lost beneath the oceans, is giving up its 60 million-year-old secrets through scientific ocean drilling," Jamie Allan, program director in the U.S. National Science Foundation's Division of Ocean Sciences, said in a statement.

Lost 8th continent

Earlier this year, scientists argued that the known seven continents had a long-lost brother Zealandia, a narrow strip of land that encompasses New Zealand and lies off the east coast of Australia, and whose landmass is mostly 3,280 feet (1,000 meters) below sea level beneath the ocean's surface. Among the evidence for Zealandia: The crust that makes up Zealandia is much shallower than the surrounding oceanic crust, and its geologic makeup looks more like continental versus oceanic crust. What's more, a narrow strip of oceanic crust separates Australia from Zealandia, which suggests the two landmasses were separate.
