Seriation, on the other hand, was a stroke of genius.First used, and likely invented by archaeologist Sir William Flinders-Petrie in 1899, seriation (or sequence dating) is based on the idea that artifacts change over time.Unfortunately, the wood from the pueblos did not fit into Douglass's record, and over the next 12 years, they searched in vain for a connecting ring pattern, building a second prehistoric sequence of 585 years.In 1929, they found a charred log near Show Low, Arizona, that connected the two patterns.Cross-dating of sites, comparing geologic strata at one site with another location and extrapolating the relative ages in that manner, is still an important dating strategy used today, primarily when sites are far too old for absolute dates to have much meaning.The scholar most associated with the rules of stratigraphy (or law of superposition) is probably the geologist Charles Lyell.

Seriation is thought to be the first application of statistics in archaeology. The most famous seriation study was probably Deetz and Dethlefsen's study Death's Head, Cherub, Urn and Willow, on changing styles on gravestones in New England cemeteries.

Until the 20th century, with its multiple developments, only relative dates could be determined with any confidence.

Since the turn of the century, several methods to measure elapsed time have been discovered.

Using local pine trees, Douglass built a 450 year record of the tree ring variability.

Clark Wissler, an anthropologist researching Native American groups in the Southwest, recognized the potential for such dating, and brought Douglass subfossil wood from puebloan ruins.
