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.
