One hundred million years ago, during what geologists call the Cretaceous period, the face of our planet was reshaping itself, yet again. The supercontinent Pangaea had broken up into the land formations we are familiar with today. But it would take another 40 million years for the continents to make the journey to where they are currently anchored.
The land mass we now call South America was an island, slowly drifting westward. Africa was in pieces. India and Madagascar were island neighbours while much of Europe was still a series of small islands. Down under, Australia’s land mass was attached to Antarctica. And while the southern polar cap had just about settled into its current position, the temperature was a balmy 10◦C/50◦F, instead of the coldest spot on Earth.
