What’s been happening in your neighborhood for the past 750 million years?

Peter Lobner

A 15 February 2019 article by Meilan Solly in the Smithsonian online magazine describes a recently released interactive map of the world that shows how the Earth’s continents have moved since 750 million years ago.   With your cursor, you can zoom in and rotate the globe in any direction. Using a pull-down menu at the top center of the screen, you can see the relative positioning of the landmasses at the point in time you selected.  A similar selection box in the upper right corner of the screen allows you to select a particular geological or evolutionary milestone (i.e., first land animals) in Earths’ development.  Even better, you can enter an address in the text box in the upper-left corner of the screen and then see how your selected location has migrated as you explore through the ages.

Following are screenshots showing what’s happened to the Lyncean Group’s meeting site in San Diego during the past 750 million years.

I hope you enjoy the interactive globe, with visualization created and maintained by Ian Webster, plate tectonic and paleogeographic maps by C.R. Scotese, and the address search tool by LocationIQ.

Current world map
20 million years ago
66 million years ago – dinosaur extinction
105 million years ago
240 million years ago – Pangea supercontinent
400 million years ago – first land animals.  Looks like the first land animals couldn’t have emerged from the sea in San Diego.
600 million years ago – Pannotia supercontinent
750 million years ago
