The Plio-Pleistocene is an informally described geological pseudo-period, which begins about 5 million years ago (Mya) and, drawing forward, combines the time ranges of the formally defined Pliocene and Pleistocene epochs—marking from about 5 Mya to about 12 kya.
The name Plio-Pleistocene has, in the past, been used to mean the last ice age. Formerly, the boundary between the two epochs was drawn at the time when the foraminiferal species Hyalinea baltica first appeared in the marine section at La Castella, Calabria, Italy. [ 20 ]
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 2.59 to 1.81 Ma, and is now included in the Pleistocene.

Her dissertation, published in 1975, showed that the composition of the fossil vertebrate faunas of East Turkana, Kenya, varied with sedimentary environment (channel, floodplain, lake margin), and this provide new information on the taphonomy and paleoecology of hominin-bearing, Plio-Pleistocene sediments .

The Norwich Crag Formation is a stratigraphic unit of the British Pleistocene Epoch. It is the second youngest unit of the Crag Group, a sequence of four geological formations spanning the Pliocene to Lower Pleistocene transition in East Anglia.
Members of the Homotherium genus were widespread through Eurasia, Africa and the Americas during the Plio-Pleistocene period (5 million years ago to 12,000 years ago).
The Shungura Formation is a stratigraphic formation located in the Omo river basin in Ethiopia.It dates to the Late Pliocene to Early Pleistocene. Oldowan tools have been found in the formation, suggesting early use of stone tools by hominins.
Early Pliocene, Plio-Pleistocene, Late Pleistocene, Holocene Bolt's Farm is a palaeontological site in the Cradle of Humankind World Heritage Site, Gauteng province, South Africa. With more than 30 fossil deposits dating back 4.5 Ma, it is one of the oldest sites currently discovered in the Cradle of Humankind.
