After the Dinosaurs Died, Evolution Went Completely Insane

66 million years ago, an asteroid the size of a mountain ended the 165-million-year reign of the dinosaurs in a single afternoon. But that wasn't the end of the story — it was the start of the strangest, most creative chapter in the history of life on Earth. Join us LIVE for a full documentary journey through the Cenozoic Era — the 66 million years of chaos, experimentation, and explosive diversification that followed the extinction of the dinosaurs. From wolf-sized whales with four legs, to ten-foot "terror birds," to saber-toothed marsupials and forty-foot snakes, this is how a handful of small, hidden survivors rebuilt an entire planet — and eventually became us. #Evolution #Paleontology #Dinosaurs #NaturalHistory #DeepTime #PrehistoricLife #Megafauna #Documentary #LiveStream 📌 ABOUT Sleepy History Past: Hi, welcome to my channel Sleep History Past.
