Definition of Term

supraorbital crest

(English) On the neurocranium, an arched horizontal plate of the cartilage forming the dorsal edge of the orbit on each side; it arises from the medial orbital wall and the cranial roof and extends horizontally from the preorbital process to the postorbital process. It is apparently primitive for shark-like fishes but is variably reduced or absent in some living elasmobranchs. (See also: orbital, preorbital, postorbital)
