Last month, researchers were able to map majority of the land mass of Zealandia, which was considered the lost eighth continent. This month, a group of Dutch geologists have found another lost continent which is said to have broken off from Australia some 155 million years ago. It's called Argoland, and they have detected tectonic "mega-units" of it scattered on the ocean floor.
After it broke off from Australia, researchers said it drifted westward to Southeast Asia and disappeared until they found traces of it stretched throughout the Indian Ocean and Southeast Asia. Estimates indicate that it once spanned 3,000 miles and parts of it can also be found in Myanmar and Indonesia. From the remnants they had found, the researchers were able to piece together what Argoland looked like until it became fragmented and later sunk at the bottom of the sea.
