One hundred and sixty million years ago, the north-western half of Gondwana consisted of the vast area that was to become South America and Africa. It extended right up to the equator and had almost separated from the northern supercontinent of Laurasia. Forming the south-eastern portion of Gondwana, and not quite grazing the South Pole, was the combined area of what we now know as Antarctica, India and Madagascar, and Australasia.
