Cenozoic (66 million years ago until today) means ‘recent life.’ During this era, plants and animals look most like those on Earth today. Periods of the Cenozoic Era are split into even smaller parts known as Epochs, so you will see even more signposts in this Era. Epoch, unit of geological time during which a rock series is deposited.

For example, the extinction of the dinosaurs ...The oldest of the geological eras is the Eoarchean, which began approximately four billion years ago. The majority of the fossil evidence that we have for primate evolution comes from the Cenozoic era —the current geological era, dating from 65 million year ago (MYA) to the present. The Cenozoic era is divided into a series of epochs.Geologists have traditionally divided the Cenozoic Era into two periods: Tertiary and Quaternary, with each period further divided into epochs. Although “Tertiary” and “Quaternary” are still widely used, a different scheme for designating Cenozoic time is becoming increasingly popular. This scheme is reflected in the International Commission …Geologic map of the near side of the Moon (high resolution, click to zoom).

After much debate,

The geological Periods can be further subdivided, into Epochs and Ages. At the finest levels, most day-to-day practical time-slicing (or geological correlation, to be more correct) is still done using fossils. Some fossils aren’t very good for this - dinosaurs, for instance, which are large and rare and geographically restricted.
