The new season takes viewers into the Pleistocene era, millions of years after the extinction of the dinosaurs, as it has never been seen before. It features strange cycles of hot and cold that create shifting landscapes and a wide variety of mammals with complex behaviors, many resembling animals alive today, fighting to survive. Fans get their first look at clashes between woolly rhinos and saber-toothed cats, based on scientific knowledge gained from fur, soft tissues, and stomach contents preserved in permafrost and only recently discovered. Alongside the era’s most iconic animals, like woolly mammoths and Dire wolves, viewers will explore five new astonishing habitats to encounter many incredible creatures that adapted to this strange new world, including: the Columbian mammoth, a warm-weather relative of the woolly mammoth with curved tusks over 16 feet wide and sparse hair (Mammuthus columbi); 14-foot-tall bears, the largest to ever exist (Arctotherium angustidens); armadillos bigger than cars (Doedicurus clavicaudatus); and tiny elephant relatives (Stegodon sumbaensis) preyed upon by enormous giant storks (Leptoptilos robustus).
