Basically what we're…what we're looking at is a massive graveyard.
It's the ghost of oceans past, essentially.
I've never seen anything like this before.
Picture this: a hundred million years ago, a lot of the Southern U.S. was underwater.
The geology created by this ancient ocean played a starring role in the story of cotton…and as a result, in the events that shaped African American history.
How did ancient rocks shape the legacy of slavery in our not-so-distant past, and how are these stories being revealed today through modern science?
I'm evolutionary biologist Shane Campbell-Staton, and this is Human Footprint.
Exactly what is it that I'm looking at here?
Yeah, you're seeing a million and a half years here.
Wow.
