The Neogene traditionally ended at the end of the Pliocene epoch, just before the older definition of the beginning of the Quaternary Period; many time scales show this division.
By dividing the Cenozoic era into three (arguably two) periods (Paleogene, Neogene, Quaternary) instead of 7 epochs, the periods are more closely comparable to the duration of periods in the Mesozoic and Paleozoic eras.
The International Union for Quaternary Research (INQUA) counterproposed that the Neogene and the Pliocene end at 2.588 Ma., that the Gelasian be transferred to the Pleistocene, and the Quaternary be recognized as the third period in the Cenozoic, citing the key changes in Earth's climate, oceans, and biota that occurred 2.588 Ma.

During the Neogene, the Indian Plate was deflect from its northerly drift towards the north-west.
The Neogene Period spans 22 million years, during which the world became much drier and cooler, culminating in the biotic disaster of the Pleistocene ice ages and the harsh conditions of our own day.

 On a Deinotherium (Proboscidea) finding in the Neogene of Crete   (Site not responding. Last check: )
The new report of a large mammal in the Neogene of Crete is from a site situated south of the town of Seteía (Prefecture of Lasíthi, Eastern Crete) in the vicinity of the village of Maroniá, WNW of the small settlement of Sfakiá (Fig.
The Neogene deposits of the Seteía District consist primarily of marls, clays, marly limestones and sandstones.
Gradstein (1973) recognises seven Neogene lithostratigraphic formations in the Seteía region, two of which are present around Maroniá: an underlying Skopí Formation, mainly conglomerates, sands, silts and clays with Crassostrea, Ostrea and plant remains, and the Faneroméni Formation, consisting mainly of limestones and marls with foraminiferans, sponges, algae and molluscs.

 Late Neogene Paleobathymetry, Relative Sea Level, and Basin-Margin Subsidence, Northwest San Joaquin Basin, California, ...
By the late Neogene the San Joaquin Basin had reached its present overall geographic configuration (Figure 1) and was bounded to the east by the southern Sierra Nevada and to the south and west by the San Emigdio and southern Coast Ranges (see Reid, 1995, fig.
The late Neogene San Joaquin Basin inland sea was 175 km long, 100 km wide, and connected to the Pacific Ocean at the northwest through a narrow and shallow strait (Figure 1) ~13 km wide and <50 m deep (Loomis, 1990).
Abrupt decrease in paleobathymetry at ~4 Ma may be related to rapid sediment deposition in the basin associated with increased uplift of the Coast Ranges (Loomis, 1990), coincident with eustatic sea level fall (Figure 3), and the slowing of subsidence on the basin margin (Figure 4) leading to sediment bypass.

Neogene magmatism in the central Aegean took place in a rapidly extending, continental back-arc environment.
We invited oral or poster contributions that were of relevance to understanding of Neogene magmatism, in fields that include igneous petrology and geochemistry, mineral deposits and economic geology, stratigraphic studies, geochronology, metamorphic petrology, structural geology, and paleomagnetism.
The scope of the conference was not limited to the Neogene: studies of older rocks that throw light on the origin of Neogene magmatism in the central Aegean and adjacent areas were included.

 Neogene tectonics, ore deposits, and Middle Miocene reconstruction
The objective of the Neogene task is to investigate the youngest period of geologic and metallogenic history in the study area, namely the northern Basin and Range province and the adjacent coeval Snake River plain to Yellowstone hot spot track.
Tectonic, landscape, and climate evolution during the Neogene and Quaternary led to the present configuration, exposure, and concealment of pre-Neogene mineral deposits and geology.
These include the nature and timing of bimodal and calc-alkaline volcanism; the origin of regional dike-filled crustal fractures; the influence of lakes and climate on mineralization and their evolution through time; and the effects of different stages of regional extension on mineralization, uplift, and paleosurface evolution.

 PROVENANCE HISTORY OF NEOGENE SANDSTONES FROM THE ASSAM BASIN, INDIA   (Site not responding. Last check: )
Preliminary modal analysis of sand and sandstones from the Neogene Surma and Tipam Groups indicates temporal variations in detrital composition and suggests possible source terranes related to orogenic unroofing.
Polycrystalline quartz grains, many of which are highly tectonized, are conspicuous in the Neogene sandstones from the Assam basin.
During the Neogene, the Assam basin most likely acted as a transient depocenter for the northeasterly-derived sediments that were being transported ultimately toward the topographically lower Bengal basin and the Bengal fan.

 Revised Chronology of Neogene DSDP Holes from the World Ocean - chapter 1
Although this effort is, even for the Neogene, incomplete, and is itself subject to eventual obsolecensce, we believe it represents a useful source of updated chronologic information which will be useful to any scientist wishing to work with these sections.
These selection criteria were frequently in conflict, as it was often the case that only older holes with relatively incomplete recovery had detailed range chart data available; holes often had good paleontological data for only one fossil group, etc.
There are many additional Neogene holes, some of considerable importance, which we could not include due to the above limitations, for this we must ask the reader's indulgence.

Fossils from the Neogene Meyer Desert Formation (Sirius Group), exposed on the Beardmore Glacier, 500 km from the South Pole, are the basis for reassessing the role of Antarctica in insect evolution.
The fossils of broad-nosed weevils in the subtribe Listroderina and a fly in the subfamily Cyclorrhapha are of more highly evolved insects than those described from Jurassic deposits.
The occurrence of fossils of ‘modern insects’ in Antarctica during the Neogene supports Brundin’s interpretation that Antarctica, as part of Gondwana, could have been an important center for insect evolution and radiation.
