The Paleocene Epoch (As We Understand It)

For ten million years after the asteroid, the Earth quietly rebuilt itself — ferns, then forests, the first great mammals, and the small beginnings of us. A slow walk through the world the dinosaurs left behind, made for sleep. This is the story of the Paleocene: the strange, warm, largely forgotten epoch that runs from the death of the dinosaurs 66 million years ago to a great warming ten million years later. It follows how a scorched world came back — the fern spike, the rise of the first big mammals, the giant snake Titanoboa in the tropics, the birth of the modern rainforest, and the little tree-climbers who were the beginning of the primate line. Told slowly, in a low voice, as deep time to rest inside.
