Approximately 335 million years ago the fragments of Earth's continental crust had assembled themselves into one supercontinent called Pangaea. This supercontinent was centered more or less on the equator. Between 225 and 200 million years ago,Pangaea began to breakup into the seven continents found on Earth today. The last fragment broke away from eastern Australia about 85 million years ago. This fragment is mostly underwater and its nature wasn't discovered until recently. The parts above water are New Zealand and New Caledonia.
Isolated in time and space, New Zealand and New Caledonia inherited and evolved unique lifeforms, both plant and animal. This epub contains images from New Caledonia.
