11. It has a large but slender skull with weak supraorbital ridges, and a short tail. 12. The supraorbital ridges are not expanded and do not form a knob in front of the spiracles. 13. The cranial vault and supraorbitals of the Jinniushan specimen are thinner than those of the Dali specimen. 14. Frequently involved structures include the lacrimal glands, extraocular muscles, infraorbital nerve, supraorbital nerve and eyelids. 15. The supraorbital hornlike structure above each eye consists of small, imbricate scales and is also present in juveniles. 16. Supraorbital and mandibular pressure may not be suitable for patients with head injuries, or those with periorbital swelling.17. The supraorbital gland has thus enabled the penguins'survival in such environments due to its water-filtering capability. 18. The supraorbital ridge of the skull is large, and the interorbital region is very broad with nearly parallel sides. 19. The very prominent supraorbital tentacles and cirrus on anterior nostril, and the shape of the dorsal fin are diagnostic. 20. Now they're starting to target frontal headaches and facial pain, at the supraorbital nerve just above the eye.
