What is the difference between paper papyrus palimpsest and parchment?

Papyrus is an ancient writing surface made from the pith of the papyrus plant, primarily used in Egypt. Parchment, on the other hand, is made from animal skins, treated and dried to create a durable writing surface. A palimpsest refers to a manuscript or document that has been written on, erased, and then reused, often revealing traces of the original writing. While both papyrus and parchment are original writing materials, a palimpsest specifically describes the reuse of such materials.
