Absolute dating methods anthropology
Landslides and slips can completely change the topography of an entire archaeology site burying what was once on top by that which is much older, hence reversing the strata layers.A more precise and accurate archaeology dating system is known as absolute dating and can in most circumstances provide a calendar year to the object.Since 1950 there has been a transformation in the dating techniques of archaeologists. Absolute dating is highly dependant on laboratory analysis. The shape and style of an artefact changes through time although its function may remain the same.The changing styles of pottery, glass, stoneware, and metal objects provide archaeology analysts with known progressive sequences.Once an artefact is compared to its known development date then whenever that item reappears in the archaeological record, of that or any other site, it can quickly be dated.The potential flaws in relative dating in archaeology are obvious.
The missing amount can then determine how long it took to be lost and therefore date the object to a precise period. It's just a bit frustrating when you can't get an absolute conclusion, and many differing opinions. When an archaeological site is excavated the sides of the unexcavated baulk reveals layering of subsequent settlements and activity.Stratigraphic excavation is the recording and study of these different strata as they are removed from the area.Simply assuming that an artefact is older because it was found at a lower depth in the record is only subjective science.There are many instances of deep holes being dug for rubbish pits or to locate well water that protrude into the record of older strata injecting more modern material as they are filled in over time.
