The cranial bones included Occipital, Sphenoid, Ethmoid, Interparietal, Parietal, Frontal, Temporal, and facial bones were Maxilla, Premaxilla, Palatine, Pterygoid, Nasal, Lacrimal, Zygomatic, Vomer, Turbinates and Mandible. The occipital was a single bone surrounding the foramen magnum. The foramen magnum was large and roughly oval in shape. The sphenoid resembled the shape of a bat. Foramen orbitorotundum was situated in between the wings of pre and post sphenoid bones. The interparietal was a small quadrilateral bone. The supraorbital foramen was present in the supraorbital groove. The paired incisive bones were placed on the lower part of the face. The infraorbital foramen located above the 1st cheek tooth. Facial tuberosity was placed just above the 3rd cheek tooth. Turbinate bones were delicate, scroll-like, complex bony plates. These were clearly visible in radiographs and CT scan. The CT scan showed three pair of clearly visible sinuses (frontal, maxillary and sphenopalatine sinuses). Cranial cavity was an ovoid cavity being elongated posteriorly, situated on the dorsal aspect of the nasal sinus. The total number of teeth thirty two; upper incisor and canine were absent, premolars and molars were three; lower incisors were four, canine absent, premolars and molars were three. The mandible was a paired bone and made up of two halves, which were united with immovable articulation forming mandibular symphysis. Craniometric measurements for parts of the skulls were made in this study. All investigated features were expressed as Mean±SE. The mean lengths of the skulls were found to be 42.17±0.27 cm, with the cephalic index 36.99±0.56 cm. The cranial index was 61.88±0.30 cm.The facial index were 62.48±0.37 cm. The length of mandible was 35.10±0.19 cm and height 16.80±0.13cm.ennullThesis
