Origin: Of multiple origins. Partly a borrowing from French. Partly a borrowing from Latin. Etymons: French nummulite; Latin Nummulites.

Etymology: Partly < French nummulite (Lamarck Système des animaux sans vertèbres (1801) 101) < classical Latin nummulus a coin (see nummular adj.) + French -ite -ite suffix¹, and partly < scientific Latin Nummulites, genus name (Lamarck Système des animaux sans vertèbres (1801) 101) < classical Latin nummulus a coin (see nummular adj.) + classical Latin -ītēs (see -ite suffix¹).

Zoology, Palaeontology, and Geology.

a. A fossil or extant foraminiferan of the genus Nummulites (now sometimes included in the genus Camerina) or a related genus, having a calcareous skeleton typically in the form of a flat spiral resembling a disc, and numerous in certain Tertiary strata.
