The inaugural map of the Earth's vanished continent has been released.

You may believe you're familiar with all the continents, but have you heard of Zealandia?

In 2017, a previously unknown contingent of the shores of New Zealand was discovered - making headlines globally.

Zealandia, known as Te Riu-a-Māui in the Māori language, covers more than 5 million square kilometres, making it twice the size of the subcontinent of India.

You might be asking yourself why it wasn't uncovered earlier.

The explanation lies in the fact that 95 percent of its landmass is hidden beneath the southwest Pacific Ocean, having vanished long before the arrival of humans on the planet. What remains above water are primarily a significant mountain range (the two islands of New Zealand) along with a few smaller oceanic islands.
