What Wikipedia says

Rostrum (from Latin rostrum, meaning beak) is a term used in anatomy for several kinds of hardened, or bony, beak-like structures or extensions projecting out from the skull or mouthparts of an animal. Despite some visual similarity, many of these are phylogenetically unrelated structures in widely varying species.
