Caudal rib

From Wikipedia, the free encyclopedia

A caudal rib is a rib that occurs in the tail of a vertebrate. They are commonly present on the more anterior caudal vertebrae of reptiles. In many taxa, they are fused with the vertebrae.[1] In taxa where the caudal ribs are fused to the vertebrae, the terms "transverse process" and "caudal rib" are sometimes used interchangeably, but the caudal rib may form only part of the transverse process.[2]
