Etymology

It is borrowed from French fossile (16th century),[2][3][4] from Latin fossilis, dug up,[2][3][5] from fossus, past participle of fodere, to dig (see bed).[2][3][5]

Earliest recorded meaning

As an adjective, obtained by digging, found buried in the earth: 1563 in the OED;[6] as a noun, a rock or mineral dug out of the earth, 1619 in Barnhart, the 1610s in Etymonline.[2][3] The NODE says it first denoted a fossilized fish found, and thought to have lived, underground.[7][8]

Semantic evolution

Fossil fishes were believed in the 17th century to live in water underground (1661).[6] The narrower sense, the remains of a plant or animal of a past age preserved in rock, is from 1665,[2][6] for the noun 1736 in Etymonline.[3] The slang sense, an old or old-fashioned person, is first recorded in 1859.[3] Fossil fuel (1833 in Etymonline, 1835 in the OED) keeps the older, broader sense.[3][6] Fossilize is from 1794.[2]
