The present study was carried out on the third to fifteenth coccygeal vertebrae of six specimens of adult Blue bull (Boselaphus tragocamelus) of either sex. The Cy3-Cy6 presented complete arches and spinous processes. The transverse processes and cranial non-articular processes were present in Cy3-Cy6 and then reduced in caudal part of the series. The transverse processes were found to be plate like that were directed downward, backward and exceeded beyond the level of the posterior articular surface of the body in Cy3. They were reduced to tubercles in were reduced to tubercles in Cy4-Cy7 and disappeared beyond Cy7. The neural rings were found to be complete in Cy3-Cy4 and then became reduced in Blue bull. The dorsal supraspinous processes were found to be thin and flat in Cy3-Cy4. | Gross morphological and sex wise morphometrical studies on the third to fifteenth coccygeal vertebrae of blue bull Boselaphus tragocamelus
