Until the 1820s, hardly anyone even suspected that dinosaurs had ever existed. In the years since, paleontology has sought to discover the entire history of life on earth, from the era of single-celled organisms up into the human era. Paleontologists continue to make remarkable discoveries, such as that a huge meteorite that fell in the Gulf of Mexico wiped out the dinosaurs—all except the birds, the only surviving dinosaurs. "Radiometric dating" can reveal the age (often tens of millions of years) of a rock or fossil or a tiny grain of pollen by measuring how much its radioactive elements have disintegrated. The study of molecules of DNA, RNA, and proteins has also become important for dating. Paleontologists often consult with geologists searching for oil, gas, and coal deposits, since all these "fossil fuels" were formed from plant and animal remains.

Word History

Etymology

borrowed from French palaeontologie (later paléontologie), from palae- pale- + ont- (probably from Greek ónta "the things that exist, reality," noun derivative from neuter plural of ont-, ṓn, present participle of eînai "to be") + -o- -o- + -logie -logy — more at is

Note: The French noun was introduced by the zoologist Henri-Marie Ducrotay de Blainville (1777-1850), as a heading for a summary of work done on fossils in 1821 ("Analyse des principaux Travaux dans les Sciences physiques, publiés dans l'année 1821"), in Journal de physique, de chimie, d'histoire naturelle et des arts, tome 94 (janvier 1822), p. liv. Blainville had earlier (tome 90, 1820, p. 80) used palaeosomiologie in the same sense (for "l'étude des corps organisés fossiles," i.e., the study of fossil organisms), in an effort to find a word that included the remains of both plants and animals, but he seems to have judged this coinage inadequate and replaced it with palaeontologie. See Martin J. S. Rudwick, Worlds before Adam: The Reconstruction of Geohistory in the Age of Reform (University of Chicago Press, 2008), pp. 48-49.
