fossilized
Ancient and preserved
Fossilized describes something that has become a fossil—organic matter preserved in rock over geological time.
The word extends to anything rigid and outdated: fossilized thinking, fossilized bureaucracy.
In linguistics, a fossilized form is a word or phrase preserved from an earlier stage of the language, no longer productive but still used: to and fro, in lieu of.
