What does vertebrated mean?
Vertebrated is a formal, relatively uncommon adjective meaning that something—typically an animal—has vertebrae, the series of small bones or cartilage units that make up the backbone. It can characterize a creature, a species, or a fossil specimen: “The museum identified the fossil as vertebrated after locating a row of vertebrae.” The word is especially associated with zoological and comparative-anatomy language, where it provides a descriptive equivalent of “vertebrate” in contexts that call for an adjective. It should not be confused with vertebrate, which can be either a noun naming an animal with a backbone or an adjective belonging to that category, nor with vertebral, which usually means “of or relating to vertebrae” rather than “having vertebrae.” Although perfectly intelligible in modern English, vertebrated sounds more learned and traditional than the everyday term vertebrate. Its usefulness lies in its precision and historical flavour: it allows a writer to discuss the presence of vertebral anatomy directly while preserving the specialised, classificatory tone of scientific prose.

"Early naturalists used vertebrated animals as a broad contrast with creatures regarded as having no backbone."
Vertebrated has a backbone—and so does its meaning: it means “having vertebrae.”
