What If the Asteroid Hit the Ocean Instead of Land?

The prehistoric sea that once covered the American Midwest – and the extraordinary marine fossils that farmers still find in their fields today

If you have ever driven across the endless cornfields of Kansas, Nebraska, or Iowa, it is hard to imagine that all of it was once under warm, shallow ocean water.

Ten thousand years ago, give or take a millennium, something enormous and slow finally gave way. Ice sheets that had buried entire continents for tens of thousands of years began retreating, and within a geological blink, mammoths, giant sloths, saber-toothed cats, and dozens of other outsized creatures vanished from the planet almost entirely.
