basioccipital

In such a mammal as a Beaver (Figure 28), a line ('a b '.) drawn through the bones, termed basioccipital, basisphenoid, and presphenoid, is very long in proportion to the extreme length of the cavity which contains the cerebral hemispheres (' g h '.).

On Some Fossil Remains of Man Thomas Henry Huxley 1860

Among the remains, the team noticed a spherical bone, called a basioccipital condyle, found in all mammals and reptiles that joins the base of the skull to the spinal cord.

The basisphenoid develops, like the basioccipital, in the flat _basis cranii_, but towards its anterior edge, between the large foramen (_h_) and the pituitary space (_i_).

The "bodies" of these vertebræ are the body of the occipital (basioccipital), the two bodies of the sphenoid (basi - and pre-sphenoid), and the vomer.

The bones developed in relation to these cranial elements can be classified as follows: -- (1) the basioccipital, exoccipitals (paroccipitals?), supraoccipital and

As an example of serial homology we might take the centra of the vertebræ -- the vomer, the presphenoid, the basisphenoid, the basioccipital and the series of centra in the spinal column.

The basioccipital is formed in the posterior part of the _basis cranii_, and the exoccipitals in the side walls of the trench in continuity with the fundament of the basioccipital (see Fig. 11).

Vertebrates consists, according to Müller, of three vertebræ, whose centra are the basioccipital, the basisphenoid and the presphenoid.

Now of these bones, the basioccipital is in every way equivalent to a vertebral centrum, for it develops in the basilar plate round the notochord.
