Rostrum (from Latin rostrum, meaning beak) is a term used in anatomy for several kinds of hard, beak-like structures projecting out from the head or mouth of an animal. Despite some visual similarity, many of these are phylogenetically unrelated structures in widely varying species.
Rostral and caudal: In animals with linear nervous systems, the term rostral (from the Latin rostrum, meaning "beak") is synonymous with anterior and the term caudal (from the Latin cauda, meaning "tail") is synonymous with posterior. Due to humans having an upright posture, however, our nervous system is considered to bend about 90°.

The guard—also known as the rostrum, scabbard, gaine, and sheath [36] —is the part of the animal most likely to be fossilized. [ 5 ] [ 29 ] Guards are difficult to distinguish at the species level, and, consequently, synonyms are common and inflate the group's apparent diversity. [ 32 ]
