Typology (archaeology) - Wikipedia
In archaeology a typology is the result of the classification of things according to their physical Another early example is the typology published in by Flinders Petrie for the objects (mainly .

Geological time-scales Accurate knowledge of the age of the Earth was of little direct help to archaeologists, but it emphasised the potential of scientific dating techniques. The first half of the twentieth century witnessed similar progress that began with the dating of recent geological periods in which early hominids lived, and ended with the introduction of radiocarbon dating. Tour of geologic time 'Here you can journey through the history of the Earth, with stops at particular points in time to examine the fossil record and stratigraphy.
Inthe British physicist Lord Rutherford--after defining the structure of the atom-- made the first clear suggestion for using radioactivity as a tool for measuring geologic time directly Climatostratigraphy While some geologists concentrated on the age of the Earth, others studied distinctive surface traces left behind by changes in the extent of polar ice during the most recent Quaternary geological period. They identified a succession of Ice Ages alternating with temperate conditions glacials and interglacials which - if they could be dated - would reveal much about the evolution of early humans in the context of changing environmental conditions.
Temperatures from Fossil Shells 'An example of the ingenious technical work and hard-fought debates underlying the main story is the use of fossil shells to find the temperature of oceans in the distant past. Helens volcano A typical volcano that has a long history of eruptions that can influence short-term episodes of climate change detectable in ice-core records Volcano World 4. Varves Sections cut through lake beds in glacial regions reveal a regular annual pattern of coarse and fine layers, known as varves.
Variations in climate produced observable differences in the thickness of sediments, and, like the patterns of variation in tree rings, this allows matches to be made between deposits in separate lake beds. For earlier periods there are several problems. The Egyptians dated by the year of reign of the king on the throne for example 'year 3 of king X'.
If we knew the precise length of reign for every Egyptian king, chronology would be no problem. However, we do not even know the number of kings for all periods, and there is also the possibility that reigns overlapped by coregency or in times of political disunity. For their own religious and administrative purposes, the Egyptians compiled lists of kings, sometimes with the exact length of reign.
Fragments of such lists survived ' Palermo stone ' ; none of them is well enough preserved to solve every detail of absolute chronology.Our Method on Typology
Kinglists in Greek, apparently compiled by a third century BC Egyptian priest named Manetho, are preserved in summaries by early Christian writers, with excerpts in other writers of the Roman Period and later, notably the Jewish historian Josephus. Methods of dating objects typologies Artefacts often have a distinctive style or design, which developed over a period of time.
dating in archaeology
In archaeology, the gradual changes in motifs were exploited systematically as a dating method by researchers from Montelius onwards. In Egyptology the method was first used by Petrie for dating the Naqada period, from the development of the so-called wavy-handled pottery.
However, there are several problems. Thus, for example, the type "Flagstaff Black-on-white" was first defined using a collection from the vicinity of Flagstaff, Arizona, and its primary design attribute is the use of black paint on a white background. Non-archaeologists should be aware of the limitations of ceramic typology.
All such typologies are abstractions, and fail to describe all of the variability in an artistic tradition. Professional disagreement over specifics is common. Changes in ceramic design did not happen overnight, and archaeological typologies tend to break continua of design evolution into arbitrary but highly useful units.
Most archaeological dates are approximate. Non-archaeological typology as an art form[ edit ] In the middle of the twentieth century, German photographers Bernd and Hilla Becher  raised typology to an art form by photographing countless similar architectural features including water towers, workers' houses and industrial landscapes. They documented their work in books.

It is based on the physical characteristics and the external features of an artifact. Some examples of morphological and descriptive typologies would be categorizing artifacts distinctively on their weight, height, color, material, or whichever class the individual decides upon. So, the projectile points could be sorted by weight, height, color, material, or however the archaeologists prefers. One of the first national typology bases available on the web, The Projectile Points Typology Databaseexhibits how the arrowhead artifacts found are classified among the fifty states by region, state, or nationwide.
