also known as the ice age, however there were many ice ages or glacial as they are known. It was the time of the Homo erectus.
Pleistocene
a cold episode of the Pleistocene in contrast to a warmer or interglacial period, also known as ice age.
Glacial
a subdivision of geological time, millions of years long representing units of eras.
Epoch
a warm period of the Pleistocene
Interglacial
During the 1800 two Swiss geologists identified 4 periods of glaciations in Europe, from a series of alpine deposits and river terraces.
A.Penck and E. Bruckner
Glacial stages named after local rivers in order from oldest to most recent-
the gunz, the mindel, the riss, and the wurm.
The intervening warm periods were?
gunz/mindel mindel/riss and riss/wurm
the expansion of continental glacial ice during a period of a cold climate.
Glaciation
one of several atomic states for an element.
Isotope stages: for the Pleistocene, alternations between warmer and cooler periods defined by isotopes have been numbered sequentially.
Isotope
the ratio of different isotopes of oxygen varying with the temperature of the water.
Oxygen Isotope Ratio
are accumulations of dirt and rocks that have fallen onto the glacier surface or have been pushed along by the glacier as it moves. The dirt and rocks composing.
Moraines
1920- Serbian mathematician argued that variation in the earths orbit changed climate in a cyclical fashion.
Milankovitch
A term describing the phenomenon considered to be the prime reason for glacial fluctuations and climatic change.
Milankovitch Forcing
the interval that we presently occupy- aka postglacial or the present interglacial.
Holocene
Revealed a series of remarkable shrine and centers associated with large stone architecture. Major changes are taking place in the region before the domestication of plants and animals. Human society is undergoing a major transformation in economy, social relations, politics and religion. Revolution understanding of Eurasian Neolithic. Oldest Human made stone structure discovered and it was called first temple.
Gobekli Tepe, Turkey

Adze
the movement of carbon isotopes through the food chain. The differences in the types of plants consumed or the presence of marine foods in the diet will result in changes in the carbon isotope ratio.
The information used to estimate the diet of prehistoric human groups?
The carbon atoms in collagen occur in two major stable forms?
carbon -12 and carbon -13.
The ratios from vedbaek range from ?
13.4 to -15.3 and are close to values for historical Eskimo skeletal material.
Nitrogen isotope ratio is used for what?
to tell if they eat a lot of leguminous plants and trophic level.
vegetables used as food
Leguminous plants
an organism’s position in the food chain.
Trophic Level
provided for the protection of archaeological resources located on public lands and Indian lands?
1979- archaeologist resources protection act
the survey and or excavation of archaeological and historical remains threatened by construction and development.
Cultural resource management
