Which is the earliest epoch listed in the Cenozoic?

Explanation:
Paleocene is the earliest epoch among the Cenozoic epochs. The Cenozoic begins after the end-Cretaceous mass extinction, about 66 million years ago, and its first epoch is the Paleocene (roughly 66–56 million years ago). After that comes the Eocene, then the Oligocene, and later the Miocene. Because Paleocene precedes the other listed epochs, it is the oldest. This period marks the recovery and diversification of mammals as ecosystems reorganized after the dinosaur extinction.
