Geologists have long known that around 155 million years ago, a 5,000 km long piece of continent broke off western Australia and drifted away. They can see that by the ‘void’ it left behind: a basin hidden deep below the ocean known as the Argo Abyssal Plain. The underwater feature also lends its name to the newly formed continent: Argoland. The structure of the seafloor shows that this continent must have drifted off to the northwest, and must have ended up where the islands of Southeast Asia are located today.

    Any time I dive into geological stuff it always amazes me how scientists can piece together the ancient world from literal fragments.
