Seriation can be used to date just about anything! Sir William Flinders Petrie, who had assemblages from various Predynastic Egyptian cemeteries, first implemented this dating method. Sir Petrie. Objects evolve over time based both on style and function, and these changes can be organized and tracked to form relative dating chronologies over various archaeological sites to get a better understanding of the development and spread. It is also worth noting that different types of artifact change in style decoration and shape at different rates, and therefore vary in the chronological distinctions that they indicate.
Before the advent of absolute dating methods, nearly all dating was relative.
The main relative dating method is stratigraphy. Absolute dating is the term used to describe any dating technique that tells how old a specimen is in years.
These are generally analytical methods, and are carried out in a laboratory. Absolute dates are also relative dates, in that they tell which specimens are older or younger than others. As archaeologists examine artifacts, they notice how the different styles are common, or trendy, at different times.
While one style may be popular now, it likely will have been less popular early on and will likely become less popular later. As popularity of a style changes so does how common it is, so the more popular it is the more examples of it archaeologists will find. With this in mind, archaeologists track how common a style of artifact or site is over time to see which may be older and which may be newer. Seriation is one of the oldest dating methods used by archaeologists, and is still very important today!
Archaeologists use many dating methods at the same time in order to determine the age of an artifact or date of a site, so it is important for them to be mindful of the different clues and samples that may help them learn more.

This pattern creates what we call a battleship curve, and this is the shape we look for when trying to configure our seriation sequence.

Apr 05, Seriation in archaeology is a relative dating technique where artefacts and assemblages (collections of artefacts) are separated and classified by style and frequency to create a relative chronology. Seriation can be used to date just about anything! First used, and likely invented by archaeologist Sir William Flinders-Petriein , seriation (or sequence dating) is based on the idea that artifacts change over time. Like tail fins on a Cadillac, artifact styles and characteristics change over time, coming into fashion, then fading in popularity.
Let's do an experiment here:. So what we do, is we find garbage pits or junkyards from that century, and take some samples.
Samples of different cell phones found in different landfills. We then take all the phones we found from each site and make a graph of all the data to see how much of each phone we found at each site.
Dating techniques are procedures used by scientists to determine the age of a specimen. Relative dating methods tell only if one sample is older or younger than another; absolute dating methods provide a date in years. The latter have generally been available only since Nov 06, Seriation is one of the oldest dating methods used by archaeologists, and is still very important today! Like all relative dating methods seriation can't tell you exactly how old a site is in absolute year, but it can help you estimate its age. Jul 27, Seriation, also called artifact sequencing, is an early scientific method of relative dating, invented (most likely) by the Egyptologist Sir William Flinders Petrie in the late 19th century.
Next, we take these bars that we just created and separate them according to type. From there, we sort them out to make what we call a battleship curve. Trends usually form in this way, starting small, getting bigger and then tapering out again.
We look at all the sites in relation to one another and move them around until we get a pretty decent timeline. And there you go!
