A study was conducted on the gross features of the splenchnocranium of an aged great Indian horned owl and its morphological peculiarities were correlated with its possible functions. The horizontal plate of ethmoid was wide and well developed. The lacrimal was very large and the lower orbital ring was incomplete. The external nares were oval in shape. The premaxilla was steeply curved down and had a hooked tip. The maxilla was highly reduced and formed a movable articulation with the palatine and zygomatic bone. The rod like zygomaticus formed a movable articulation rostrally with the maxilla and caudally with quadrate. The paired palatines were horizontal in position and formed the strong bone of the upper jaw. The pterygoid was a thin short and which articulated cranially with palatine, behind with parasphenoid process of presphenoid and caudally with quadrate. | Gross anatomy of the splanchnocranium in the great Indian horned owl (Bubo bengalensis)
