Eras divide into periods and periods divide into epochs.

The Palaeozoic Era is composed of the Cambrian, Ordovician, Silurian, Devonian, Carboniferous and Permian periods (in that order). The Mesozoic Era is divided into the Triassic, Jurassic and Cretaceous periods. The Cenozoic Era is divided into the Tertiary and Quaternary periods. The Tertiary period is divided into the Palaeocene, Eocene, Oligocene, Miocene and Pliocene epochs while the Quaternary period is divided into the Pleistocene and Holocene epochs.

Note that eras are not the longest lengths of time. Eras may compose longer stretches of time known as eons/aeons.
