    If you’ve ever been to, or lived in, or even flown over the central swath of North America, then you’ve seen the remnants of what was a uniquely fascinating environment. Scientists call it the Western Interior Seaway, and at its greatest extent, it ran from the Caribbean Sea to the Canadian Arctic.

    Thanks to Dmitry Bogdanov, Nobu Tamura, C.R. Scotese, NASA and the many others listed throughout the video for making their images available to use.
