The anal sinus is deep, about one-third of the way from the carina to the suture.

Homaloceras is the most primitive, with a laterally compressed, cyrtoconic to gyronic shell with a narrow, concave venter, broadly convex flanks, and rounded dorsum, The suture is only slightly sinuous, the siphuncle tubular and near the venter.

The suture is with a shallow ventral lobe and broad lateral lobes with subacute saddles on the shoulders; the siphuncle is tubular, near the venter; the living chamber half a volution in length.

The suture is with ventral and dorsal lobes, the siphuncle very close to the venter.

The suture has a ventral saddle and broad lateral lobe and the siphuncle is small and near the venter.

The suture is with broad, deep lateral lobes, the nature of the ventral and lateral lobes is unknown, as is the position of the siphuncle.

Phacoceras as a moderately involute, highly compressed, smooth, lenticular shell with an acute venter and widest at the umbilical shoulder; suture with ventral saddle and broad shallow lobes on flanks; siphuncle slightly ventral from center.

The suture is of the "Paraceltites" type with 8 unserrated lobes and long, anteriorly, contracted club-shaped external saddles.

The suture is generally with squarish, symmetrical, deeply and sharply indented saddles.

Prolene is a synthetic, monofilament, nonabsorbable polypropylene suture.

It is often used in conjunction with the absorbable suture Monocryl.

It is used in obstetrical practice, during cesarean sections to suture the rectus sheath of the abdominal wall because it is non-absorbable in nature and provides the sheath the due strength it deserves (rectus sheath is composed of various tendon extensions and muscle fibres and maintains the strength of the abdominal wall, if it becomes weak the abdominal contents start herniating out) it stays there forever and is also often seen during repeat cesarean section as that of the previous section.

The other whorls have each 3 spirals, of which the uppermost runs at a little distance from the suture.

The next one is the strongest. It renders the whorls carinate about halfway, and a third which seems to run just in the rather conspicuous suture.

This spiral sculpture is crossed by radiating riblets, running straight in an oblique direction, from the suture to the upper spiral, where they form small crenulations.

The aperture is moderately large, irregular in shape, with a rather deep sinus at the suture (about 1½ mm, behind the most projecting part of the outer margin).

The suture is ammonitic with long spikey lobes and saddles with rounded subelements.

The maxilla and praemaxilla are completely fused with no visible suture.

It is crossed in front by the coronal suture and behind by the lambdoid suture, while the sagittal suture lies in the medial plane between the parietal bones.

The right-lateral strike slip Tintina Fault occurs along the suture zone between the YTT (on the south and west) and ancestral North America to the east; it forms a significant boundary between North America cratonic rocks and rocks of the YTT and associated terranes - although displaced continental rocks are found south of the Tintina Fault and pieces of the YTT occur north of the Tintina Fault. Parts of the YTT have been offset by at least 400 km along the Tintina Fault. In most of the Alaskan part of the YTT the Denali Fault forms the modern day southern boundary of the terrane.

The term comes from the Greek words "hymen" meaning "membrane", and "raphe" meaning "suture".

The longitudinal ribs are numerous, rounded, not prominent, not interrupted on the periphery but continuous to the suture.

The suture has a dark purple colour and is impressed.

"P. carpenteri" also possesses a unique combination of characters, including: low dentary alveolar count including only 18 postsymphysial alveoli, and a total count of 27; intermediate low count of syphysial alveoli including only 9; teeth fully trihedral, possessing a flat, anteroposteriorly broad labial surface lacking enamel ridges; mediolateral expansion of caniniform regions of the premaxilla and maxilla relatively pronounced, although this might be due to crushing; six closely spaced premaxillary alveoli; anisodont premaxillary dentition; diastema present between maxillary and premaxillary alveolar rows; premaxilla–parietal suture located level with the anterior region of the orbit; cervical centra lacking ventral ridge; and epipodials with highly convex proximal surfaces.

The subrectangular sheet of the maxilla extends anteriorly on alveolar surface of the premaxilla to contact the distalmost premaxillary alveolus, while in other species of "Pliosaurus" an interdigitating premaxilla-maxilla suture is located mid-way between the mesialmost maxillary and distalmost premaxillary alveoli.

"P. kevani" also possesses a unique combination of characters, including: high dentary alveolar count including 22 postsymphysial alveoli and an estimated total count of 36–37; high count of symphysial dentary alveoli including at least 7, estimated as 14–15; subtrihedral teeth, possessing a suboval cross-section with slightly flattened labial surface bearing only thinly distributed enamel ridges; pronounced mediolateral expansion of caniniform regions of the premaxilla and maxilla; six closely spaced premaxillary alveoli; anisodont premaxillary dentition; and premaxilla–parietal suture located level with the anterior region of the orbit.

It also has a long, sheet-like process of the maxilla that extends back to the anterolateral part of the maxilla–frontal contact medial to the external naris, and terminates just anterior to midlength of the orbital. Finally, the suture between the premaxilla and parietal bone is located around orbital midlength.

The whorls are nearly straight, but slightly convex in the upper part, slightly concave near the lower suture.

The whorls are prominently keeled above the suture, the keel being finely crenulate.

The Tightrope CCL technique utilizes a very strong suture material called FiberTape and isometric placement of small bone tunnels to provide bone-to-bone fixation while not causing the trauma of cutting through the bone of the tibia like a TPLO - tibial plateau leveling osteotomy or TTA - Tibial tuberosity advancement procedure.

The body whorl is elongated, rounded in the middle, appressed below the suture, convex beneath.

The palatomaxillary suture is a suture separating the maxilla from the palatine bone.
