Phenoscape Knowledgebase (BETA): supraoccipital crest

entity term: supraoccipital crest

Properties

ID: TAO:0001783

Ontology: Teleost Anatomy

Synonyms: supraoccipital process, supraoccipital spine

Definition: Process that is part of the supraoccipital. It is a posteriorly directed and unpaired median projection off the posterior margin of the supraoccipital bone.

Comment: The supraoccipital crest may be small and restricted to the dorsal part of the supraoccipital, or may be large and long and extending ventrally to the dorsal margin of the foramen magnum. The supraoccipital crest may be a large process extending above the skull roof in some teleostean subgroups.
