Paleocene Epoch (66 to 56 million years ago) With the dinosaurs gone, mammals began to fill the roles of large herbivores and carnivores. Condylarths, the first hoofed mammals, were forerunners of today’s horses, cows, sheep, deer, and antelopes. Primitive carnivores evolved into the dog, cat, and weasel families, and the first whales.The Triassic Period (252-201 million years ago) began after Earth's worst-ever extinction event devastated life.
