A paired bone forming part of the palate of many vertebrates
Skull diagram of Champsosaurus, showing the pterygoid bone
The pterygoid is a paired bone forming part of the palate of many vertebrates, behind the palatine bones.[1]
It is a flat and thin lamina, united to the medial side of the pterygoid process of the sphenoid bone, and to the perpendicular lamina of the palatine bone.[2]
