The Himalayan range which boasts of some of the highest points on the planet has not been the same during ancient times.

What we see now the towering Himalayan mountains were once under the sea. This is why marine fossils are commonly found high up in the range. The Himalayas were once underwater, in an ocean called the Tethys Ocean.

Both the Himalayan mountain range and Tibetan plateau have formed as a result of the collision between the Indian Plate and Eurasian Plate which began 50 million years ago and continues today.

225 million years ago India was a large island situated off the Australian coast and separated from Asia by the Tethys Ocean.
