The French word 'paléontologie' was introduced in 1822.
Notes on verification
Corroborated by multiple independent sources including dictionaries, French Wikipedia/Wiktionary, and a specialized paleontology history article, all attributing the term's coinage to Henri Ducrotay de Blainville in 1822.
