Endochondral bone that sutures with the pterosphenoid anteriorly, the sphenotic and pterotic dorsally, the parasphenoid ventrally, the basioccipital postero-ventrally, the exoccipital posteriorly, and occasionally, with the intercalar posteriorly. The dorsal edge of the prootic contributes to the hyomandibular facet. The prootic bears foramina that accommodate branches of the trigeminal and facial nerves. The prootic is a paired bone.[TAO]
