Turbinals are bony or cartilaginous structures that present in the nasal cavity of most tetrapods. They involved key functions such as olfaction, heat, and moisture conservation, well protection respiratory tract. Despite recent studies challenged long-standing hypotheses about their physiological genomic correlation, turbinals remain largely unexplored, particularly for non-mammalian species. Herein, we review synthesise current knowledge using an integrative approach includes comparative anatomy, physiology, histology genomics. In addition, provide synonyms correspondences tetrapod from 80 publications. This work represents a first step towards drawing homology whole clade, provides strong basis to develop new research avenues.
