A time interval of the Cenozoic era, lasting from 23.7 to 1.6 Ma and incorporating the Miocene and Pliocene epochs. If the Tertiary is designated as an era, then the Neogene and the Paleogene are its two periods.
The Neogene period is the interval of geological time from 24 to 1.8 million years ago. Neogene is derived from the Greek word for recent.
A period of geological time, dating from about 25 to 2 million years ago.
The Neogene (24 million to 1.8 million years ago) was the later part of the Tertiary Period. It is divided into the Miocene Epoch (24 million to 5 million years ago, when many mammals appeared, including the horses, dogs, bears, South American monkeys, apes in southern Europe, and Ramapithecus; also, modern birds appear) and the Pliocene Epoch (5 million to 1.8 million years ago, when the first hominids (australopithecines) developed, modern forms of whales appeared, and Megalodon swam the seas).
The later of the two periods into which the Cenozoic era is divided according to the European nomenclature of geologic time.
the later of two periods of the Cenzoic era, comprising the Miocene, Pliocene, Pleistocene, and Recent epochs. The earlier period is the Paleogene; the system of rock strata formed during this period or system. [AHDOS
Neogene Period is a unit of geologic time starting 23.03 Â± 0.05 million years ago. The Neogene Period follows the Paleogene Period of the Cenozoic Era. Under the current proposal of the International Commission on Stratigraphy (ICS), the Neogene would consist of the Miocene, Pliocene, Pleistocene, and Holocene epochs and continue until the present.Lourens, L., Hilgen, F., Shackleton, N.J., Laskar, J., Wilson, D., (2004) â€œThe Neogene Periodâ€.
