Morphologically, these are very interesting tortoises, with a particularly short supraoccipital crest and a notably deep, narrow snout with unusual nasal passages. ❋ Darren Naish (2006)
The rostrum in rorquals is long and tapers to a point (though it is comparatively broad in blue whales) and, in contrast to other mysticetes, a stout finger-like extension of the maxillary bone extends posteriorly, overlapping the nasals and abutting the supraoccipital (the shield-like plate that forms the rear margin of the skull). ❋ Darren Naish (2006)
While most birds have just one occipital condyle, hornbills have two, as there is an accessory one on the supraoccipital (the bone that forms the upper border to the foramen magnum). ❋ Darren Naish (2006)
When ossification sets in, the ear-capsule forms three bones, of which two fuse with the supraoccipital and exoccipitals. ❋ Unknown (N/A)
The supraoccipital is an accessory bone developed in relation to bigger brains. ❋ Unknown (N/A)
The supraoccipital is formed in cartilage above the exoccipitals. ❋ Unknown (N/A)
Completing the three hinder cranial "vertebræ" and roofing in the brain are the supraoccipital, the parietals and the frontals. ❋ Unknown (N/A)
The bones developed in relation to these cranial elements can be classified as follows: -- (1) the basioccipital, exoccipitals (paroccipitals?), supraoccipital and ❋ Unknown (N/A)
So, too, the supraoccipital in man cannot be fully homologised with the supraoccipital of many mammals, for its upper half arises at first in isolation as a secondary bone (p. 290). ❋ Unknown (N/A)
An element, perhaps supraoccipital, terminates in a free appressed apex on each side of the median pos - terior region. ❋ Unknown (1771)
Pariotichus Copef agrees in the main with Chilonyx, but the supraoccipital is divided medially and is reflected onto the superior face of the skull as in Stegocephali. ❋ Unknown (1771)
The component elements of the cranial roof are equal in number and similar in position to those of the Stegocephalian skull, except that the supramastoid extends between the parietal and intercalare to the posterior border of the cranial table (Fig. 2, 8m.); and the supraoccipital does not extend onto the superior face of the skull, except as a narrow border. ❋ Unknown (1771)
Summing up as regards the cranial vertebræ Rathke writes, "We find that the four different groups of bones, consisting of the basioccipital with its intercalary (the supraoccipital), the basisphenoid with its intercalaries (parietals), the presphenoid with its intercalaries ❋ Unknown (N/A)
Soemmering is the special homologue of the supraoccipital bone of the cod, although it is developed out of pre-existing cartilage in the fish and out of aponeurotic membrane in the human subject. "[ ❋ Unknown (N/A)
