  Miocene epoch. The Columbia Encyclopedia, Sixth Edition. 2001-05
Miocene rocks are found along the Atlantic as far N as Martha’s Vineyard, but the series, everywhere thin, is thickest and least interrupted from New Jersey to Maryland.
The mammalian life of the Miocene was marked by further stages in the development of the horse, by the multiplication and final extinction of the giant hogs, and by the appearance of the mastodons, raccoons, and weasels.
In the Miocene a distinct cooling of the climate resulted in the reduction of forests and an increase in grassy plains.

 Miocene - Wikipedia, the free encyclopedia
The Miocene epoch is a period of time that extends from about 23 to 5.3 million years before the present.
The Miocene follows the Oligocene Epoch and is followed by the Pliocene Epoch.
The subdivisions within the Miocene are defined by the relative abundance of different species of calcareous nanofossils (calcite platelets shed by brown single-celled algae) and foraminifera (single-celled protists with diagnostic shells).

 Palaeos Cenozoic: Miocene: The Miocene Epoch
During the late Miocene the island continent of India slammed into Asia, pushing up the Himalayas and triggering a global cooling that was to culminate in the Pleistocene ice ages.
Later in the Miocene a distinct cooling of the climate resulted in the further reduction of both tropical and conifer forests, and the flourishing of grasslands and savanna in their stead.
The Miocene saw the continuation of bioregional provinces in some instances, and great mammal migrations in other cases, as animals that had evolved on different continents during the Eocene and Oligocene spread via land-bridges.

The elevation of the Alps, and probably of the whole Alpine system of mountain folds from Morocco to Indo-China, though initiated by earlier Miocene and late Oligocene movements, took place mainly during the latter part of the Vindobonian period, and was completed in the Sarmatian.
The Miocene was a period of change, of mountain-building, climatic differentiation hitherto unprecedented, and of moderation in organic life, especially on land.
The spread of turf-forming grasses was succeeded in the Pontian by an enormous increase of herbivorous mammals, including Hip parion and horned ruminants (Helladotherium, Antilope, Cervus, Camelopardalis, Palaeotragus), whose migrations were facilitated by the desiccation of the Medi terranean basin.

 THE METAL OBSERVER - Band History - MIOCENE
MIOCENE offstage are quiet, happy to argue amongst themselves and smoke as much weed as they can without simply floating away - but onstage they snap, and become demonic, energized, as if someone flips a switch on their angry machine.
In the year and a half since MIOCENE exploded onto the UK's incredibly fertile Hardcore/Metal scene, their profile has gone from strength to strength: from being an "insiders-only" secret, playing incendiary live shows in packed venues before a demo was released, to being the most talked-about band London has seen for years.
The future is bright for MIOCENE too; they are currently holed up in the studio, working on the follow-up album to "Refining The Theory!" (released in December 2000 on Infernal Records), and are once again aiming to push back even more boundaries and expand on their already distinctive brand of noise.

 MIOCENE TROBRIAND FOREARC BASIN
During the early and middle Miocene, the Trobriand forearc was extensional and a forearc basin developed that filled with sediments up to 5-7 km thick (Tjhin, 1976; Pinchin and Bembrick, 1985; Francis et al., 1987).
This Miocene forearc basin history is amply documented west of 151°E by commercial wells (Goodenough 1 and Nubiam 1) and seismic surveys (Tjhin, 1976; Pinchin and Bembrick, 1985; Francis et al., 1987).
The middle Miocene was a time of deepwater deposition of (silty) shales with tuffaceous interbeds that in the late Miocene shoaled upward during deposition of the thick Nubiam shale (Fig.

 Miocene epoch --  Encyclopædia Britannica
It is often divided into the Early Miocene epoch (23.7 to 16.6 million years ago), the Middle Miocene epoch (16.6 to 11.2 million years ago), and the Late Miocene epoch (11.2 to 5.3 million years ago).
The term Oligocene is derived from Greek and means the “epoch of few recent forms,” referring to the sparseness of the number of modern animals that originated during the Oligocene.
The Miocene was a period of volcanism and mountain building, during which the topography of the modern world was becoming established.

Miocene basaltic-rock aquifers consist primarily of flood-type basaltic lava flows that were extruded from major fissures; some flows extend along former lowlands for about 100 miles.
In the Miocene basaltic lava flows, some of the open spaces that initially formed during cooling or subsequently formed during folding have been filled with secondary clay minerals, calcite, silica, or unconsolidated alluvial deposits emplaced by streams or in lakes.
Permeability of the Miocene basaltic-rock aquifers is extremely variable.

 Evidence for Late Miocene Reactivation
To assess the lateral extent of Late Miocene reactivation, samples were obtained from transects perpendicular to the belt in the Marysandi River and Darondi Khola, central Nepal, the Bhagirathi River, Garhwal Himalaya, and Dudh Kosi, south of Mt. Everest [Figure 1].
Late Miocene monazite ages from rocks collected along transects spaced ~20 km apart in central Nepal and over 400 km west in the Garhwal Himalaya reveal evidence of widespread reactivation of the MCT and development of the MCT Zone.
The widespread occurrence of Late Miocene recrystallization in the inverted metamorphic sequences strongly suggest that the presently exposed inverted metamorphic sequences and Early Miocene crustal melts are not temporally related and thus there is little justification in seeking a causal relationship between the two.

Reef-rimmed progradational platforms were widespread in the western Mediterranean during the late Miocene (Esteban, 1979, in press).
The Upper Miocene rocks of the Balearic archipelago (Mallorca, Menorca, Ibiza, Formentera and smaller islands) are commonly flat-lying limestones and dolostones,with only slight tilting and flexure, probably caused by normal and strikeslip faulting in the Late Neogene to Middle Pleistocene.

 Rednova NEWS | Miocene Songbirds and the Composition of the European Passeriform Avifauna   (Site not responding. Last check: 2007-10-26)
From the early Miocene of Australia, crown-group oscines have been reported and even assigned to distinct extant genera (Boles 1995b, 1997), thus corroborating molecular phylogenies that indicate an origin of oscines on the Australian continental plate.
Because of the geological age of the specimens, we consider it likely that absence of the six-canal pattern in the fossil hypotarsi is indeed primitive and indicates that the taxa are outside the crown-group Eupasseres.
Few late Oligocene or early to middle Miocene songbirds have been described from Europe so far, and all were considered to be within the Eupasseres -representatives either of the suboscines (Ballmann 1969, Mourer-Chauvir 1995, Cheneval 2000) or of the oscines (MourerChauvir et al.
