The Pliocene (; also Pleiocene) Epoch (symbol P) is the epoch in the geologic timescale that extends from 5.333 million to 2.58 million years BP. It is the second and youngest epoch of the Neogene Period in the Cenozoic Era. The Pliocene follows the Miocene Epoch and is followed by the Pleistocene Epoch. Prior to the 2009 revision of the geologic time scale, which placed the four most recent major glaciations entirely within the Pleistocene, the Pliocene also included the Gelasian stage, which lasted from 2.588 to 1.806 million years ago, and is now included in the Pleistocene.
As with other older geologic periods, the geological strata that define the start and end are well identified but the exact dates of the start and end of the epoch are slightly uncertain. The boundaries defining the Pliocene are not set at an easily identified worldwide event but rather at regional boundaries between the warmer Miocene and the relatively cooler Pliocene. The upper boundary was set at the start of the Pleistocene glaciations.

The Origin of Species, many scientists found incised and broken bones indicating a human presence in the Pliocene, Miocene, and earlier periods.
Nonetheless, reports of incised and broken bones indicating a human presence in the Pliocene and earlier are absent from the currently accepted stock of evidence.
Certainly, there is not sufficient reason to categorically reject these bones as evidence for a human presence in the Pliocene.
If any time-travelers had brought budwood from improved stonefruits, the resulting trees might have been too susceptible to Pliocene insects and diseases to survive without chemical protection.

Some of the bones were from museum collections, and others were excavated personally by Capellini from Pliocene formations around Siena, at places such as Poggiarone.
Pliocene period, a warm sea washed the southern slopes of the Alps, depositing layers of coral and molluscs.
Millions of years ago, during the Pliocene period, a warm sea washed the southern slopes of the Alps, depositing layers of coral and molluscs.
Pliocene deposits formed in high latitudes have to a great extent been swept away by the subsequent glacial wearing, they indicate by their fossils a climatal change in the direction of greater cold.
For example, there is an almost total absence of fossils linking the Miocene apes such as Dryopithecus with the Pliocene ancestors of modern apes and humans, especially within the span of time between 4 and 8 million years ago.
Britain, man of sufficient intelligence to fashion flints and to build a fire, before the close of the Pliocene time and before the advent of the First Glaciation.
