It’s important to note that while cross-dating provides a flexible methodology for temporal analysis, additional methods such as seriation could be employed for more depth and precision. Seriation, an archaeological technique that involves arranging artefacts in chronological order based on stylistic or typological changes, can be particularly useful. It is a relative dating method that relies on the premise that styles or types of artefacts change progressively over time and can, therefore, be used to place archaeological contexts into a sequence. However, it’s necessary to acknowledge that formal seriation may not be universally applicable, as its effectiveness largely relies on the site types and the range and scale of material culture present.
For instance, sites with an extensive and varied collection of artefacts, where observable shifts in design or material use occur, are best suited for formal seriation. In other cases, an informal sequence could be more appropriate. This might be particularly useful when dealing with finds of similar character or when identifying groups of material that imply an earlier or later date – once issues of residuality and intrusion have been factored in.
By approaching seriation with flexibility, it can be aligned more closely with the realities of the archaeological record. It’s about taking into account the artefacts’ similarity in character and the impact of temporal outliers, which could be embedded into a loose sequence. This sequence, though less rigid than a formal seriation, would nonetheless contribute to a more nuanced understanding of the site’s chronology.
