Paired cartilage bone that bears a large foramen (lateral occipital foramen). Contacts the supraoccipital dorsally, the epiotic laterally and the basioccipital ventrally. Forms the posterior hind margin of the cranium and borders the lateral and posterior margins of the forum (foramen) magnum.

editor note

TODO - check FMA - currently we place this as both of a zone of bone organ and an (endochondral) bone. Removed endochondral bone classification for now, violates disjointness axiom

external comment

In some teleosts the exoccipital dorsally contacts the supraoccipital directly or through connective tissue.[TAO]

external definition

Endochondral bone that forms the posterior end of the neurocranium and the margin of the foramen magnum. In addition, this bone forms either part of or all or the occipital condyle.[AAO]

Endochondral bone that articulates with the epiotic dorsally, the pterotic and intercalar laterally and the basioccipital medio-ventrally. The exoccipitals form the lateral borders of the foramen magnum and houses the foramina for the passage of the vagus and glossopharyngeal nerves, X and IX respectively. The exoccipital is a paired bone.[TAO]
