Pangea was the latest in a line of supercontinents in Earth’s history.

Pangea began developing over 300 million years ago, eventually making up one-third of the earth’s surface. The remainder of the planet was an enormous ocean known as Panthalassa.

As time goes by, scientists are beginning to piece together more information on the climate and patterns of life on the supercontinent. Similar to parts of Central Asia today, the center of the landmass is thought to have been arid and inhospitable, with temperatures reaching 113ºF (45ºC). The extreme temperatures revealed by climate simulations are supported by the fact that very few fossils are found in the modern day regions that once existed in the middle of Pangea. The strong contrast between the Pangea supercontinent and Panthalassa is believed to have triggered intense cross-equatorial monsoons.

By this unique point in history, plants and animals had spread across the landmass, and animals (such as dinosaurs) were able to wander freely across the entire expanse of Pangea…

Since the average continent is only moving about 1 foot (0.3m) every decade, it’s unlikely you’ll ever be alive to see an epic geographical revision to the world map.

However, for whatever life exists on Earth roughly 300 million years in the future, they may have front row seats in seeing the emergence of a new supercontinent: Pangea Proxima…

As we go with the flow, we might send historic birthday greetings to Dorothy Annie Elizabeth Garrod; she was born on this date in 1892.  An archaeologist who specialized in the Palaeolithic period, she was the first women to hold a chair at an Oxbridge university, serving as of Disney Professor of Archaeology at the University of Cambridge from 1939 to 1952.
