basicranial

In the Cervidae and Giraffidae the face is not bent down on the basicranial axis as it is in the Bovidae.

Some of the most important structural features that mark it as such are in the basicranial region.

The posterior part of the craniofacial axis, which has relations only with the cranium, is called the basicranial axis.

Of these, one of the largest is the parasphenoid which, in Ichthyopsids, is found underlying the basicranial axis.
