This Map Lets You Plug in Your Address to See How It's Changed Over the Past 750 Million Years

The interactive tool enables users to home in on a specific location and visualize how it has evolved between the Cryogenian period and the present

Some 240 million years ago, the patch of land that would one day become the National Mall was part of an enormous supercontinent known as Pangea. Encompassing nearly all of Earth’s extant landmass, Pangea bore little resemblance to our contemporary planet. Thanks to a recently released interactive map, however, interested parties can now superimpose the political boundaries of today onto the geographic formations of yesteryear—at least dating back to 750 million years ago.

The results are intriguing: During the early Triassic epoch, the National Mall in Washington, D.C., for example, was wedged almost directly adjacent to Mauritania, yet to be separated from the Northwest African country by the vast waters of the Atlantic Ocean.

Ancient Earth, the tool behind this millennia-spanning visualization, is the brainchild of Ian Webster, curator of the world’s largest digital dinosaur database. As Michael D’estries reports for Mother Nature Network, Webster drew on data from the PALEOMAP Project—spearheaded by paleogeographer Christopher Scotese, the initiative tracks the evolving “distribution of land and sea” over the past 1.1 billion years—to build the map.

Users can input a specific address or more generalized region, such as a state or country, and then choose a date ranging from zero to 750 million years ago. Currently, the map offers 26 timeline options, traveling back from the present to the Cryogenian period at intervals of 15 million to 150 million years.

So interesting! Had no idea that Pangea looked like that. Wonderful! Quite a bit of water around then! Judi Lynn Nov 2023 #19
It really is! I created ten or so subject tabs of each epoch and some of the creatures to read today. littlemissmartypants Nov 2023 #20

Thanks for turning everyone on to the link. But I thought the earth was only 6000 years old, where's the button for 6000 years ago. Only asking for a non friend.

So much there to unpack.

That our planet is fifty percent or more water and that we know so little about the contents blows my mind, too.

Thanks so much for your reply and encouraging words, Judi Lynn. I really enjoy your posts!
