Vellum

Vellum is derived from the Latin word “vitulinum” meaning "made from calf", leading to Old French “Vélin” ("calfskin"). It is mammal skin prepared for writing or printing on, to produce single pages, scrolls, codices or books. It is a near-synonym of the word parchment, but "vellum" tends to be the term used for finer-quality parchment.
