	Glacial Period - LoveToKnow Watches (Site not responding. Last check: 2007-10-31)
		The periodicity of glacial advances and retreats, demanded by those who believe in the validity of so-called " interglacial " epochs, is explained by a series of complicated processes involving the alternate depletion and completion of the normal charge of carbon dioxide in the air.
		In addition to the stratified deposits and their contents, important evidence in favour of interglacial epochs occurs in the presence of weathered surfaces on the top of older boulder clays, which are themselves covered by younger glacial deposits.
		The cause of the interglacial hypothesis has been most ardently championed in England by Professor James Geikie; who has endeavoured to show that there were in Europe six distinct glacial epochs within the Glacial period, separated by five epochs of more moderate temperature.

		It has been suggested also that the end of this cold period was responsible for the subsequent Cambrian Explosion, a time of rapid diversification of multicelled life during the Cambrian era.
		It is now perhaps more common (before the previous interglacial to the current (Holocene) one, the Eemian) to refer to periods by their Marine isotopic stage number.

		The colder periods are called 'glacial periods', the warmer periods 'interglacials', such as the Eemian interglacial era.
		The complex pattern of changes in Earth's orbit and the change of albedo may influence the occurrence of glacial and interglacial phases — this was first explained by the theory of Milutin Milankovic.
		In particular, during the last 800 thousand years the dominant inter/glacial oscillation has been 100 thousand years, which corresponds to changes in Earth's eccentricity and orbital inclination, and yet is by far the weakest of the three frequencies predicted by Milankovic.

	HighBeam Encyclopedia - Pleistocene epoch (Site not responding. Last check: 2007-10-31)
		Since the interglacial periods of the Pleistocene were of longer duration than the time elapsed since the end of the Pleistocene 11,000 years ago, it is sometimes suggested that the Holocene, or Recent, epoch, which is occurring now, may be merely another such interglacial stage and that the glaciers may return at some future time.
		The characteristic formation laid down in the glacial stages of the Pleistocene, as in all glacial periods, is the drift.
		The interglacial stages were marked by the weathering of the till of the drift to form a sticky, heavy soil called the gumbotil and by the deposition of peat and loess.

		In application to the interglacial intervals the term Age is quite appropriate; however, the application of Stage is not so clear because the physical record of much of this time is preserved in soil profiles that represent the alteration of earlier rocks.
		The name Yarmouth was proposed by Leverett (1898b) to apply to the soil that served to separate the tills of Kansan and Illinoian ages in east-central Iowa.
		It is the oldest of the interglacial Ages to be based on a buried soil.

		The Hoxnian interglacial (and is analogous to the Yarmouth interglacial in North America, the Holsteininterglacial in northern Europe and the Mindel-Riss interglacial in the Alps) isa name for an interglacial period which occurred between 300,000 and200,000 years ago.
		It was a warm period and its deposits directly overlie material from the preceding Anglian glaciation and lie beneath those from the following Wolstonian glaciation.
		The name Hoxnian interglacial is used by British geologists and archaeologists who named it after the Hoxne in the English county of Suffolk where some of the deposits itcreated were first found.

		The peoples of India lay stagnant, with a civilization that was unprogressing; the yellow man was consolidating his holdings in central Asia; the brown man had not yet begun his civilization on the near-by islands of the Pacific.
		During the previous hunting era the superior tribes had intermarried with the higher types of war captives and had unvaryingly destroyed those whom they deemed inferior.
		Man ordinarily evolved into a farmer from a hunter by transition through the era of the herder, and this was also true among the Andites, but more often the evolutionary coercion of climatic necessity would cause whole tribes to pass directly from hunters to successful farmers.

	Lepe Beach, Hampshire - Geology of the Wessex Coast
		The interglacial deposits are now generally considered to be mainly estuarine sediments of the Ipswichian (last) Interglacial, although the matter is not simple and recent papers on the subject, such as that of Brown et al.
		The authors thought that as at Selsey, the gravel apparently overlying the interglacial deposit was marine and is related to the same marine transgression that produced the brackish water conditions.
		It is obvious that the limestones of Black Rock and Hampstead Ledge are the same, and that the visible outcrops must once have swept round northward and southward near Yarmouth to close in the basin, for neither the limestone nor the overlying clays continue as far as the present coast-line of the mainland.

		Thus, the Paleozoic Era refers to ‘‘ancient life,’’ the Mesozoic Era to ‘‘medieval life’’ and the Cenozoic Era to ‘‘modern life.’’ Rocks older than Paleozoic generally lack diagnostic fossils and are widely known as belonging to the Precambrian Era.
		This era included about 80 percent of Earth's history, that is, from nearly 5 billion years to 800 million or 700 million years ago.
		Of particular significance is the investigation of the stratigraphic records of sea floors that has led to new views on the length and frequency of glacial and interglacial episodes.

	Only one Ice Age (Site not responding. Last check: 2007-10-31)
		An interglacial is the period between ice ages when all of the glaciers melted, except for Antarctica and Greenland.
		This mainly consists of presumed interglacial deposits between layers of till and the old appearance of some glacial debris, especially in the north-central United States.
		In conclusion, the idea that these clay layers represent interglacial times between ice ages is a stretch.

	Glaciers
		In North America, there were at least four major glaciations separated by warm interglacial periods during the Great Ice Age beginning 1.6 m.y.a.
		These advances include the Nebraskan, the Kansan, the Illinoian, and the Wisconsinan glacial cycles and the Aftonian, Yarmouth, the Sangamon and the present interglacial.
		Evidence from the Illinoian and Wisconsinan glacial periods are easier to interpret than older ones because sediment deposits are directly accessible on the glacially shaped landscape.

		In particular, during the last 800 thousand years the dominant inter/glacial oscillation has been 100 thousand years, which corresponds to changes in Earth's eccentricity and inclination, and yet is by far the weakest of the three frequencies predicted by Milankovic.
		The reasons for preferring one frequency to another are poorly understood and an active area of current research, but the answer probably relates to some form of resonance in the Earth's climate system.

		Each time Era (except the first) is divided into Periods (e.g., the Cenozoic into the Quaternary and the Tertiary) and Periods are further divided into Epochs (e.g., the Tertiary into the Pliocene, Miocene, Oligocene, Eocene, and the Paleocene).
		For each time period, whether an Era, Period, or Epoch, there is a corresponding rock formation by which the time period has been dated.
		Rock formations constituting a specific (time) Era form a Group of rocks; those rocks having been formed during a specific (time) Period constitute a rock System; and those rock formations originating during a specific (time) Epoch are said to belong to a particular Series of rocks.

		It may have been possible for Seaside Sparrows, if any were then in existence, to have gained a footing on Floridian shores during sub- sequent glacial stages of the Pleistocene Epoch.
		During the last part of the Wisconsin glacial era when the sea level dropped to minus 25 feet or more, it might have been possible (and probably was) for the ancestral sparrow to populate the west shoreline of Florida then lying several miles out in what is now the Gulf of Mexico.
