Etymology: "Squamella" is a diminutive of the Latin "squama," meaning "a scale," the same word that gave English "squame" and "squamous." The Latin ending "-ella" shrinks the base noun, so the term denotes a little scale: a thin, flat plate that overlaps its neighbours, as on a fish, a reptile, or the bracts of a plant. The base word itself was used across Latin for anything plated or layered, from fish scales to the scaly armour of soldiers, and the diminutive simply narrows that image to something small and flat. Biologists borrowed the form in the same spirit, so the term is best read as a scientist's refinement of an ordinary Latin image rather than an ancient coinage.
