In a manner relating to or according to the methods of archaeology; from an archaeological perspective.
From 'archaeologic' + '-ally' (adverb suffix). This adverbial form allows speakers to describe how something is done using archaeological methods or understanding.
When scientists say something is 'archaeologically significant,' they're using this adverb to mean it matters for understanding human history—like finding a 2,000-year-old finger bone that rewrites everything we thought we knew about human migration.
