For the sake of simplicity, only the epochs of the Paleogene, Neogene, and Quaternary periods are shown on the time scale at the top of this page. It is important to note, however, that all of the periods of the Phanerozoic era are subdivided into the epochs and ages. The Cenozoic epoch is the most recent, and its name signifies "new life." This is due to the fossils' resemblance to modern-day animals and flora.-The era in which we live is the Cenozoic era. -The period in which we live is a quaternary period. -The epoch in which we live is the Holocene. Note: The key issue in chronology is synchronizing ...The Paleocene Epoch/Series is the first of the Cenozoic Era /Erathem. It is the first of five epochs in the Tertiary Period and the first of three in the Paleogene, which is treated either as a period in its own right or as a subdivision of the Tertiary. The Paleocene succeeds the Cretaceous Period/System and precedes the Eocene Epoch. The Cenozoic Era’s first period is the Paleogene period.
