Seriation sequence dating dating when you are disabled

Sequence Dating, a relative dating method, allows assemblages to be arranged in a rough serial order, which is then taken to indicate time.

Sequence dating is a method of seriation developed by the Egyptologist Sir William Matthew Flinders Petrie.

Outside evidence, such as dating of two or more stages in the development, may be needed to determine which is the first and which the last member of the series.

Flinders Petrie excavated at Diospolis Parva in Egypt in the late nineteenth century.In archaeology, seriation is a relative dating method in which assemblages or artifacts from numerous sites, in the same culture, are placed in chronological order.Where absolute dating methods, such as carbon dating, cannot be applied, archaeologists have to use relative dating methods to date archaeological finds and features.Absolute dating techniques were not available to him (radiocarbon dating wasn't invented until the 1940s); and since they were separately excavated graves, stratigraphy was no use either.Petrie knew that styles of pottery seemed to come and go over time--in his case, he noted that some ceramic urns from the graves had handles and others had just stylized ridges in the same location on similarly shaped urns.
