Etymology: "Clavarium" appears to be built from Latin "clava", meaning "club", plus the suffix "-arium". In Latin, "-arium" formed nouns for a place or container where something is kept, as in "herbarium" and "aquarium". A structure that holds or houses a part of the body fits that pattern. The club link is harder to see for something shell-shaped, so the exact route from "club" to "shell" is uncertain. The suffix, however, is clear and the same one found in many modern scientific coinages made from Latin parts.

Synonyms: clavicle, key bone
