Ep. 1: The Ordovician (2019-08-23)

For nearly 4 billion years, the continents of Earth were lifeless. But during the Ordovician, there was an explosion of life beneath the sea. Many strange creatures evolved, from eel-like conodonts to voracious cephalopods, until nearly all life was wiped out in our planet’s first mass extinction.
Ep. 2: The Devonian (2019-08-23)

Life in the sea rebounded with a vengeance in the Devonian. Dozens of monstrous predators emerged, like the 40-foot long Dunkleosteus. Nearly everything was wiped out in Earth’s second mass extinction. But the stage was set for an explosion of life on land.
