Sawing of three men, from a 15th-century print Death by sawing was the act of sawing or cutting a living person in half, either sagittally (usually midsagittally), or transversely. Death by sawing was a method of execution reportedly used in different parts of the world, but most frequently in Mediaeval Europe.

The dimples of Venus (also known as back dimples, butt dimples or Veneral dimples) are sagittally symmetrical indentations sometimes visible on the human lower back, just superior to the gluteal cleft. They are directly superficial to the two sacroiliac joints, the sites where the sacrum attaches to the ilium of the pelvis. An imaginary line joining both dimples of Venus passes over the spinous process of the second sacral vertebra.

The palate has a pronounced, sagittally elongated vault that is formed primarily by the vomers. The vomers contact the premaxillae at a level with the maxillary tooth margin towards the tip of the rostrum. However, it does curve strongly dorsally towards the palatines, and so we see the choanae very far above the tooth margin. To withdraw the choana further from the oral cavity, the vomerine and palatine borders of the choana are recessed dorsally.

The body of Ductina is small to average (up to ), 1¼ to 2 times as long as wide, blunted oval. Body without any adornment. The headshield (or cephalon) is 2 to 3 times as wide as it is long in the direction of the axis (or sagittally). The cephalic axis (or glabella) is strongly widening forward with shallow furrows, the front curving downward to end at an approximate straight angle to the plain of the axis.

The combination of animal's vertebral strength and its convex curvature behind the shoulder kept its vital organs from being crushed in the demonstration. The feat represented a weight of roughly 1000 times the animal's body weight, the equivalent of a human holding 10 elephants. Relative to body size, the hero shrew's spine is roughly four times more robust than any other vertebrate (excluding its sister species). Despite its great strength, the hero shrew's spine is easily flexed sagittally (the muscles for doing this are well developed).

These are low-crowned, bulbous teeth that are set in sockets. The vomer of T. borealis, on the other hand, has six high, triangular teeth that are fused to the bone. T. alexandrae had only a single row of teeth present but the vomer must have developed as a paired structure, so it can be assumed that there must have been more than a single row of teeth. The bone is split sagittally and it is possible that an additional row of teeth was present but broke away during preservation.

This may have allowed a humanlike stride in A. sediba. The hip joint appears to have had a more humanlike pattern of load bearing than the H. habilis specimen OH 62. The birth canal of A. sediba appears to be more gynaecoid (the normal human condition) than those of other australopiths which are more platypelloid, though A. sediba is not completely gynaecoid which may be due to smaller neonate brain (and thus head) size. Like humans, the birth canal had increased diameter sagittally (from front to back) and the pubis bone curled upwards.

Dr. Phillip Habgood discovered that the characters said to be unique to the Australasian region by Thorne are plesiomorphic: Yet, regardless of these criticisms Habgood (2003) allows for limited regional continuity in Indonesia and Australia, recognizing four plesiomorphic features which do not appear in such a unique combination on fossils in any other region: a sagittally flat frontal bone, with a posterior position of minimum frontal breadth, great facial prognathism, and zygomaxillary tuberosities.Habgood, P.J. (2003). A Morphometric Investigation into the Origins of Anatomically Modern Humans. British Archaeological Reports, International Series 1176.

Schematic view of a ship's navigation lights indicating its port (red) and starboard (green) sides Port and starboard are nautical terms of orientation that deal unambiguously with the structure of vessels, referring respectively to the left and right sides of the vessel, seen by an observer aboard the vessel looking forward. Vessel structures are largely bilaterally symmetrical, meaning they have mirror-image left and right halves if divided sagittally. One asymmetric feature is that on ships where access is at the side, this access is usually only provided on the port side.

Protobranchia is a subclass of bivalve molluscs. It contains the extant orders Nuculanida, Nuculida, and Solemyida. These are deep water clams of a small and primitive order with a taxodont hinge (composed of many similar, small teeth), generally with a central ligament pit, large labial palps which are used in deposit feeding and the gills used only for respiration, the anterior and posterior adductor muscles are nearly equal in size, a foot which is divided sagittally and longitudinally with papillate margins. The foot in Protobranchia clams is without a true byssus gland, although they frequently have a nonhomologous byssal gland in the heel.

As with most early trilobites, Elliptocephala has an almost flat exoskeleton, that is only thinly calcified, and has crescent-shaped eye ridges. As part of the Olenellina suborder, Elliptocephala lacks dorsal sutures. Like all other members of the Olenelloidea superfamily, the eye- ridges spring from the back of the frontal lobe (L4) of the central area of the cephalon, that is called glabella. The head shield (or cephalon) of Ellipticephala carries backwards directed spines at the corner between the halfcircle shaped frontal and side margin and the backmargin that is roughly perpendicular to the midline. The frontal lobe of the glabella (L4) is roughly 1½× the length of the backward ring-shaped lobe (also called occipital ring or L0) and the most backward set of side lobes (L1) taken together, measured along the midline (or sagittally).
