Il Madagascar e le Seychelles sono frammenti dell’antico supercontinente di Gondwana. Quando il Gondwana iniziò a frantumarsi (circa 160 milioni di anni fa) il Madagascar si separò prima dall’Africa e solo dopo dall’India (89 milioni di anni fa). Questo isolamento ha fatto del Madagascar quello che alcuni biogeografi “ottavo continente”. The Rheic Ocean was one of the dominant oceans of the late Paleozoic. Approximately 420 million years ago it separated two large land masses: the supercontinent Gondwana, consisting of present-day South America, Africa, India, Australia, and Antarctica; and Laurussia, made up of North America, Greenland, Europe, and part of Asia. Dr Squire said the researchers believed the likely source was a now-eroded supermountain range that formed when the eastern and western halves of Gondwana collided 500 million to 650 million years ago. The erosion of the mountain range deposited huge amounts of elements including iron, phosphorus, magnesium and calcium into the ocean. Touted as the last refuge of the plants and animals that populated the ancient supercontient of Gondwana, New Zealand may in fact have once sunk beneath the waves, taking all traces of Gondwana with it. Fossils of a new crocodile-like species have been unearthed in rural Queensland, Australia. Modern crocodiles and alligators may be able to trace their roots back to this species that lived on Gondwana between 95 and 98 million years ago.
