Sagittal crests (i.e. ectocranial crests that occur at, or close to, the midline), if they appear at all in living hominoids, are more likely to occur in male than female individuals and they develop relatively late in ontogeny (i.e. their development tends to coincide with, or follow, the eruption of the permanent dentition).

A novel design departure was the tandem keel, two vertical fins with one long interconnecting weight, introduced by Warwick Collins. The idea was to combine shoal draft, 'full' keel advantages, a low centre of gravity and produce extra lift, the same as two sails do instead of only one.Homo erectus featured a flat face compared to earlier hominins; pronounced brow ridge; and a low, flat skull. The presence of sagittal, frontal, and coronal keels, which are small crests that run along these suture lines, has been proposed to be evidence of significant thickening of the skull, specifically the cranial vault.1.

In the human skull, a sagittal keel, or sagittal torus, is a thickening of part or all of the midline of the frontal bone, or parietal bones where they meet along the sagittal suture, or on both bones.

The Sagittal keel (torus) is a thickening of bone on part or all of the midline of the frontal bone, or parietal bones where they meet along the sagittal suture, or on both bones. Sagittal keels differ from sagittal crests, which are found in some earlier hominins (notably the genus Paranthropus) and in a range of other mammals.

The sagittal crest is a prominent ridge of bone that projects superiorly (upwards) from the cranial vault along its midline, most commonly seen in adult male gorillas and orangutans. Sagittal crests are rare in adult male chimpanzees and female gorillas, and are unknown in female chimpanzees, female orangutans, and humans and bonobos of both ...Joined in midline by the sagittal suture (sagittal keel/crest in some extinct hominids).
