We hereby report a bilaterally symmetrical parietal foramina in a processed skull meant for osteological practical at the Department of Veterinary Anatomy, University of Jos, Nigeria. The depths of each of the foramina were 4.3 cm, while the diameters were 1 cm. This appears to be the first report of such foramina in the skull of bovine in North Central Nigeria.
