In the spirit of yesterday’s post on the Earth of the past, this interactive map lets you browse back in time to see what oceans and landmasses looked like all the way back to 750 million years ago. Try typing in your address to see if you’d have been a resident of Gondwana or Laurasia if you took your time machine back to the Triassic.

When I read Annals of the Former World some years back, the hardest thing to wrap my head around with geologic time was the sheer scale of what “100 million years” looks like. No matter how many of the comparisons, scale bars, or timelines I see, it’s still mind-blowing to think about continents converging, separating, and reconverging repeatedly throughout history.
