Enthesophytes are bony projections that arise from the sites of ligament, tendon or joint capsule attachment to a bone. They are seen rarely in radiographic findings in young adults, as these bony adaptations are assumed to develop slowly over time. However, in recent years, the presence of an enlarged external occipital protuberance (EEOP) has been observed frequently in radiographs of relatively young patients at the clinic of the lead author. Accordingly, the aim of this project was to assess the prevalence of an EEOP in a young adult population. Analysis involved a retrospective analysis of 218 lateral cervical radiographic studies of 18-30-year-old participants. Group A (n = 108; males = 45, females = 63) consisted of asymptomatic university students, while Group B (n = 110; males = 50, females = 60) were an age-matched mildly symptomatic, non-student population. The external occipital protuberance (EOP) size was defined as the distance from the most superior point of the EOP (origin) to a point on
Lower cranial nerve (IX-XII) palsy is a rare condition with numerous causes, usually non-traumatic. In the literature it has been described only a few times after trauma, mostly accompanied by a fracture of the occipital condyle. Although these types of fractures have rarely been reported one could suspect they have been under-diagnosed. During the past decade they have been seen more frequently, most probably due to increased use of CT- and MRI-scanning. The purpose of this review is to increase the awareness of complications following injuries in the craniocervical region. We based this article on a retrospective review of the medical record of a 24-year old woman admitted to our trauma center after being involved in a car accident and a review of the literature on occipital condyle fractures associated with lower cranial nerve palsy. The multitraumatized patient had suffered a dislocated occipital condyle fracture. Months later she was diagnosed with palsy to cranial nerve IX-XII. Literature review
... On the outer surface, at the sides of the foramen carved out for the dorsal medulla, the occipital bone puts out two capitula (l, l in figures 4 and 5) [condyli occipitales] which are articulated to the first cervical vertebra [atlas], by means of which the head is tilted and extended by its own motion. In young children, these capitula [condyli] are epiphyses; in old persons they are hidden, like the other epiphyses. Also in young children, the bone is constructed of three parts [partes laterales, pars basilaris] separated by three lines [sutura] filled with cartilage [synchondroses]. One of these runs from the end of the sagittal suture to the posterior part of the foramen [foramen magnum] of the dorsal medulla; the other two [fonticuli mastoidei] extend transversely from the sides of the foramen to the extensions of the lambdoid suture. Consequently, the very young have two bones [partes laterales] in the occiput, and one [pars basilaris] attached to the ...
The occipital condyles are undersurface protuberances of the occipital bone in vertebrates, which function in articulation with the superior facets of the atlas vertebra. The condyles are oval or reniform (kidney-shaped) in shape, and their anterior extremities, directed forward and medialward, are closer together than their posterior, and encroach on the basilar portion of the bone; the posterior extremities extend back to the level of the middle of the foramen magnum. The articular surfaces of the condyles are convex from before backward and from side to side, and look downward and lateralward. To their margins are attached the capsules of the atlanto-occipital joints, and on the medial side of each is a rough impression or tubercle for the alar ligament. At the base of either condyle the bone is tunnelled by a short canal, the hypoglossal canal. Position of occipital condyles (shown in red) Skull and cervical vertebra. Occipital condyles (red) articulate with the superior facets of the atlas. ...
It is the most posterior of the cranial bones forming the posterior wall and base of the skull. It is consist of two parts; squamous part and basilar part. In between these part is the foramen magnum of the occipital bone through which passes the spinal cord. The squamous part lies posterior to the foramen magnum and the basilar part lies anterior to the foramen magnum. On the inferior surface of the basilar part just anterior to the foramen magnum lie two projections called as occipital condyles which project inferiorly and posteriorly. The occipital condyle make joint with the superior articular facets of the 1st cervical vertebrae called as atlanto−occipital joint. This joint transmits the weight of skull bones to the vertebral column and helps in making movements like when we say Yes (flexion anteriorly and posteriorly). On the posterior external part of the squamous part is the external occipital protuberance and beneath it lies two curve lines called as superior nuchal line and inferior ...
SKIN INCISIONS (Look at the following slide for reference.) In the midline make a vertical skin incision from the external occipital protuberance to the approximate level of the posterior superior iliac spines (A to B). Make a transverse incision across the iliac crest (B to C). Make transverse incisions at the level of the inferior scapular angle (D to E). Make an incision from the external occipital protuberance to the mastoid process (A to F). Make a transverse incision from the mastoid process superior to both scapulae extending to the tip of the acromion, and then extending inferiorly to midarm (F to G).

The occipital bone has an interesting developmental history. Phylogenetically, the base of the bone is the cranial most serial homologue of the vertebral series of bones. The vertebral-like endochondral portion is joined by a large plate-like lamina that develops intramembranously. This bone can be somewhat plastic in its development, but a general plan is recognized as follows. The flat upper squamous portion of the bone superior to the highest nuchal line ossifies intramembranously in two lateral centers that appear during the second embryonic month. These centers will eventually join, but sometimes remain separate from the rest of the occipital elements becoming the so called interparietal bone. It is common for additional centers to appear in the membrane associated with the squama. These centers sometimes remain unfused to the rest of the squama becoming the sutural bones common to the occipitoparietal suture. The rest of the occipital bone, everything below the highest nuchal line, is ...

The superior or upper (or descending) fibers of the trapezius originate from the spinous process of C7, the external occipital protuberance, the medial third of the superior nuchal line of the occipital bone (both in the back of the head), and the ligamentum nuchae. From this origin they proceed downward and laterally to be inserted into the posterior border of the lateral third of the clavicle. The middle fibers, or transverse of the trapezius arise from the spinous process of the seventh cervical (both in the back of the neck), and the spinous processes of the first, second, and third thoracic vertebrae. They are inserted into the medial margin of the acromion, and into the superior lip of the posterior border of the spine of the scapula. The inferior or lower (or ascending) fibers of the trapezius arise from the spinous processes of the remaining thoracic vertebrae (T4-T12). From this origin they proceed upward and laterally to converge near the scapula and end in an aponeurosis, which glides ...

This is the cranial continuation of the interspinous and supraspinous ligaments, albeit, it takes on a much different morphology than its caudal counterparts. It forms a two-layered fibroelastic septum that separates the dorsal muscles of the neck and spans from the spine of the seventh cervical vertebra to the external occipital protuberance. The deep fibers of the ligament attach to the external occipital crest, the posterior tubercle of the atlas, and to the medial surface of the bifid processes of the other cervical vertebrae ...
Using sophisticated anatomical labeling and single-unit recording techniques, we show (1) that axons of sensory neurons in C2 and C3 DRGs innervate the dura overlying the cerebellum and the posterior fossa; (2) that they enter the cranium through bony canals in the occipital bone (occipital-periotic, emissary, hypoglossal), and large foramens (magnum, jugular); (3) that they reach the occipital bone after traversing the different layers of the suboccipital muscles; (4) that nearly 50% of them originate in neurons that contain CGRP, TRPV1, but not IB4; (5) that dorsal horn neurons that receive nociceptive information from the posterior/occipital dura are located in C2-C4 spinal cord segments and that their cutaneous and muscle RFs are centered around the ears, occipital and upper neck skin, and superficial and deep neck muscles, and (6) that administration of inflammatory soup to their intracranial dural RF, sensitizes a subpopulation of them to the extent that they become hyper-responsive to ...
Discussion. The chronic intradiploic hematoma lesion was first described by Chorbski and Davis in 19341 and was named by Sato et al.2 To date, only 12 cases of chronic intradiploic hematoma have been reported in the literature.1-11 Other names found in the literature for intradiploic hematoma include non-neoplastic cyst of diploe, traumatic cyst, and giant cell repetitive granuloma.4,6,9,10,12. The exact pathogenesis of the intradiploic hematoma is not clear. However, chronic intradiploic hematomas associated with anticoagulant use, birth trauma, and shunt surgery have been reported. Moreover, acute hematomas in the various layers of the scalp and the skull usually resolve spontaneously.1 However, trauma can initiate bleeding in the diploic space. If the resulting diploic hematoma is not absorbed, the surrounding connective tissue usually encapsulates the hematoma and creates a cyst.1 The natural history of this connective tissue can show various stages of differentiation, i.e., fibrous tissue, ...

The shape and size of this cavity also depend on variables other than kinetic energy, such as yaw-the wobbling motion of a bullet-and the effect of secondary missiles that form when the bullets kinetic energy is transferred to bone, which fragments and itself becomes projectiles. When the bullet enters tissue, it chisels out a cavity much larger than its own diameter. A ball cannot produce yaw because it has no longitudinal axis to wobble on, and no secondary missiles were formed in Lincolns injury because, other than entering the occipital bone, the ball encountered only soft brain matter. The occipital bone that was hit was driven like a plug and found in the autopsy about two and a half inches down the missile track. The hole made in the bone, wrote a witness to the autopsy, "was as cleanly cut as if done with a punch." The absence of yaw and secondary missiles combined with the balls low velocity should have rendered the effect of cavitation in Lincolns wound minimal, and indeed, the ...

Behind either condyle of the lateral parts of occipital bone is a depression, the condyloid fossa (or condylar fossa), which receives the posterior margin of the superior facet of the atlas when the head is bent backward; the floor of this fossa is sometimes perforated by the condyloid canal, through which an emissary vein passes from the transverse sinus. ...
After the area is treated, the next step is to re-listen to the body. Very often the listening takes you to the left occipitomastoid suture - the suture between the temporal and occipital bones. Now if we look at our anatomy, we see that the vagus nerve exits in the jugular foramen between these two bones. We may even feel a "line of tension" between the occipitomastoid suture and the upper stomach. This would make sense anatomically because of the pathway of the esophagus and vagus nerve as they both travel through the thorax. Thus, when we "line up the tension", or engage the two structures between our hands so that we can feel a specific tension, we may release these structures and thus help the child with their symptom of reflux. ...

This week we are featuring C1. The atlas is one of the two upper cervical vertebrae, also known as C1, which is the topmost vertebra of the spinal column. It is the vertebra that is in contact with the occipital bone, a flat bone located at the back portion of the head. This first cervical bone is named from the mythical Greek god who carried the world on his shoulders, as its function is to support the globe of the head. Together with the second vertebra, the axis, it is responsible for the wide range of motion of the head. The atlas does not look like a typical vertebra, with its ring-like structure and the absence of a body, which is actually fused to the axis. ...

Schinzel Giedion syndrome is characterized by an unusual facial appearance as well as abnormalities of the skeleton, kidney, hair and brain. Individuals with this disorder have an obstruction of the tube that carries urine from the kidney into the bladder (ureter). This causes the kidney to become swollen as urine accumulates (hydronephrosis).. Failure to grow and develop normally becomes apparent at an early age. Excessive growth of hair as well as widely spaced eyes, a flat midface, low-set ears, a short low-set nose, and a short and wide neck with an excess of skin are typical features of individuals with Schinzel Giedion syndrome.. Abnormalities of the skeleton include widely spaced openings between the bones of the skull (patent fontanelles), and short lower arms and legs. Other skeletal signs may include clubfoot and broad ribs. Typical and specific findings on X-ray are a dense pyramid bone and gap between the two segments of the occipital bone.. Sudden, aimless, uncontrollable discharge ...
Acrania is a developmental abnormality characterized by a partial or complete absence of calvaria with complete but abnormal development of brain tissue. Acrania is a relatively common malformation and affects about 1 in 1000 newborns. Meroacrania refers to absence of the cranium with the exception of the occipital bone. Brain stem and cerebellum develop normally, but cerebral parenchyma tissue is covered with a thin membrane and severely dysmorphic supratentorial brain is also seen. The other system findings are normal. Magnetic resonance imaging findings of one neonate with meroacrania have been reported in medical literature. Other radiographic and computed tomography findings have not yet been reported. We report a female neonate with meroacrania with discussion of etiology, pathogenesis, radiological findings, and differential diagnosis.
Cadavers numbering twenty (20), only those with sound physical signs of good embalming were selected for this study. The cadavers were dissected in a span of two (2) years. The work started in North Bengal Medical College, Darjeeling, West Bengal and carried forward in R. G. Kar Medical College, Kolkata, West Bengal.. Instruments used for this dissection were scalpel, toothed and untoothed forceps, scissors (straight and curved), chisel (curved and straight), hammer, hand-saw, bone nibbler, bone cutter, L-retractor, and electric saw, and periostenm elevator.. The approach followed in this study is really a combination of the classical approaches for removal of brain and spinal cord (Brash J. C 1958) with an addition involving the removal of he remains of the squamous part of the occipital bone, left over after the removal of skullcap by a circumferential cut and posterior laminectomy of all vertebrae (Canale S. T. - 1998).. The cadavers selected were laid in supine position on the dissection ...
The epaxial muscles, or vertebral extensors, develop on the dorsal side of the vertebral column and skull. These muscles develop from the myotomal epimere of all the trunk somites and are found along the entire length of the vertebral column and back of the occipital bone. They comprise the intrinsic muscles of the vertebral column, which are often referred to as the "true back muscles." The vertebral extensors form four distinct muscle groups. These groups are, from superficial to deep, the spinotransversales, the erector spinae, the transversospinales, and the intersegmental muscles. However, each of the four groups does not extend the entire length of the vertebral column, so in some regions not all four layers are represented. It is also important to recognize that muscles from the upper limb and caudal branchial arch migrate superficial to the epaxial muscles and completely cover them. In general, the epaxial muscles vary in length and attach between different vertebrae along the length of ...

HOW IT WORKS A narrow strip of the donor area is trimmed to 2mm in hair length.. Local anesthetic is then administered. Dr. Gillespie prides himself on virtually painless anesthesia and has been published as well as he has taught others in regards to his technique.. A strip of hair is removed from the safe donor area, the area just above the ears towards the back of the occipital protuberance (the bump at the back of the head). This is called the donor area because the hair from from here will usually grow forever, therefore grafts taken from this area when transplanted, will continue growing for a lifetime. The scalp is carefully sutured using a trichophytic closure to minimize scarring. The hair from above the suture is then combed down to conceal the suture line.. The strip is then carefully dissected under microscopes by our experienced surgical technicians into 1 - 4 hair unit grafts. These naturally occurring groups of hairs are called follicular units ...

Posterior occipitocervical fixation and fusion are often required to address occipitocervical instability. Safe, stable internal fixation with screws is vital for the success of such surgery. Thus, poor selection of an internal fixation technique may cause fixation and fusion failure, possibly leading to neurovascular injury. Hence, in certain cases, such as in patients with severe instability of an occipitocervical deformity or osteoporosis, we hypothesized that having a third anchor point (a screw in C2) could enhance the stability of the occipitocervical fixation. A 31-year-old man with occipitocervical deformity and spinal cord edema underwent a traditional occipitocervical fixation procedure but with the addition of a spinous process screw in C2 as a third anchor point. The procedure included posterior internal fixation and fusion. The occipitocervical fixation was completed by inserting occipital screws, bilateral C2 pedicle screws, C3 lateral mass screws, and a spinous process screw in C2 as a
INTRODUCTION The increased incidence and success of strip craniectomy with postoperative helmet therapy in the treatment of sagittal craniosynostosis has been documented by multiple centers throughout the country and world. The authors report a child with a postoperative implantation intradiploic epidermoid cyst following a strip craniectomy, a complication, that to our knowledge, has not been reported. METHODS This clinical report involves a 3-year-old boy with a scaphocephalic appearance who was transferred to our center following an interstate adoption. He underwent a strip craniectomy with helmet therapy in infancy. On presentation to our facility the chief complaint was a scaphocephalic appearance. Preop computed tomography scans showed areas of bone gaps along the sagittal suture. RESULTS The child was brought to the operating room for a mid-vault expansion. At surgery, a large intradiploic epidermoid cyst was noted on the posterior aspect of the area of the sagittal suture, immediately

... is a distinct type of headache characterized by piercing, throbbing, or electric-shock-like chronic pain in the upper neck, back of the head, and behind the ears, usually on one side of the head. Typically, the pain of occipital neuralgia begins in the neck and then spreads upwards. Some individuals will also experience pain in the scalp, forehead, and behind the eyes. Their scalp may also be tender to the touch, and their eyes especially sensitive to light. The location of pain is related to the areas supplied by the greater and lesser occipital nerves, which run from the area where the spinal column meets the neck, up to the scalp at the back of the head. The pain is caused by irritation or injury to the nerves, which can be the result of trauma to the back of the head, pinching of the nerves by overly tight neck muscles, compression of the nerve as it leaves the spine due to osteoarthritis, or tumors or other types of lesions in the neck.

... The skull or cranium is composed of eight cranial bones and fourteen facial bones, which are all fused together by sutures. The skull cranial bones protect the brain and they are: one frontal, two parietal, two sphenoid, two temporal, and one occipital bones. Dome of the skull is known as the skullcap and the lower part is called the base. The largest of the facial bones are the upper and lower jaws (maxilla and mandible). At the center of the base of the skull there is hole called foramen magnum, through which the spinal cord runs. The cranium turns freely on top of the vertebral column, which is made up of separate bones called vertebra. ...

The second site is measured approximately 1 fingerbreadth diagonally up at a 45° angle from the first injection. The injections should be administered in the most superficial aspect of the muscle, angling the needle 45° and superiorly. To aid in the placement of the injections, the patient should be positioned upright with the head in a neutral position. If the neck is flexed too far forward, injections may be too deep. Injections that are too low or too deep in this muscle group can lead to muscle weakness and neck pain. Injectors should use a suboccipital approach to ensure that the injection sites ...
The Edinburgh Stereoscopic Atlas of Anatomy. Section-II-No.11. Head and Neck. Spinal Canal--No. 2. The posterior part of the skull has been removed and also the dura mater over the cerebellum and the upper part of the spinal cord. Dura mater. The cranial dura mater is adherent to the crainial wall, and serves as a periosteum to the inner surface of the cranial bones. It contains several large venous channels, many of which meet with one another at the internal occipital protuberance. Thus, at this place, the superior longitudinal sinus, which lie in the middle line and runs from in front to the back, meets the straight sinus, the orifice of which is seen, and the occipital sinus. The confluence of these channels constitutes the torcular Hierophili, and from it the lateral sinuses pass outwards on either side, lying between the cerebrum and the cerebellum. The lumen of the sinuses is rather triangular in shape. Arachnoid. This is a delicate non-vascular membrane which invests the brain and cord. ...

The unilateral transection of the cerebellar peduncles was performed on 29 rats (Table 1). In these animals the atlanto-occipital membrane was exposed and excised, and the cerebellar peduncles of one side was cut by inserting a microknife into the fourth ventricle underneath the cerebellum. These animals belong to an experimental set described in a previous study to which it can be referred for details about the surgical procedures and the evaluation of lesion extent (Buffo et al., 1998).. The Purkinje cell axonal transport was blocked in vivo by injecting a colchicine solution into the cerebellar parenchyma of uninjured rats. These animals were placed on a stereotaxic frame, the occipital bone was exposed, and a hole was drilled in the superior aspect to expose the cerebellar vermis. A total of 4 μg of either colchicine (n = 17, Table 1) or β-lumicolchicine, as a control (n = 4, Table 1), diluted in 1 μl of saline solution was pressure-injected 1 mm deep within the cerebellar parenchyma ...

There are four major sutures and one of them is the coronal suture. These sutures are what connect the brains frontal, temporal, parietal and occipital bones. Though it looks like the brain is one large bone, there are actually a number of major bones in the brain that are connected together. These bony plates covering the brain are being held together by a fibrous material which is called sutures. In this article, what we will be discussing about is the coronal suture and its function..

The entire head should be in proportion to the body. It should be long and lean with a well-defined stop. The skull, when viewed from above, should be oval. The skull should be of medium width, without coarseness, and should be only slightly wider at the base than at the brows. The widest part of the oval should be at the ear set. There should be a moderately defined occipital protuberance. The length of the skull from the occiput to the stop should be equal in length to the muzzle. Muzzle: brick-shaped, and the width to be in harmony with the skull. It should be level from the eyes to the top of the nose. When viewed from the side, the line of the top of the muzzle should be parallel to the line of the top of the skull. A dish or a Roman nose is objectionable. The flews should be square and pendant. The nose to be black or dark brown in colour except in white, orange and white, lemon and white or liver and white where it may be lighter. The nostrils should be wide apart and large in the ...
Did anyone see the piece that was done about the new surgery for Occipital Neuralgia this morning on (I believe) Good Morning America? A friend of mine saw it and said that a plastic surgeon and a neurosurgeon had teamed up and come up with a surgery that goes in and scrapes part of the muscle away from the occipital nerve to give the nerve more room. She was telling me about it because she thought it might be something I should check into. I told her that I would try to check but that I didnt have ON - I have migraines that have to do with the vessels in my head - no the nerves. Just thought I would throw it out there for any of you that suffer with ON. You can probaby can go to the Good Morning America website and find out about it ...
... refers to sharp, shooting pain arising at back of the head or upper neck, and spreading either to the top of the skull, or to the temple region. This is frequently associated with a dull or throbbing pain behind the eye. It may occur on both sides. This pain is often reproduced by applying mild pressure or tapping over the greater or lesser occipital nerves at the back of the skull. Some patients may have pins and needles or numbness over the scalp ...
The head should be opened with a stainless-steel handsaw to avoid aerosol formation. An electrically-powered saw contained within a plastic bag may be used as an alternative. Standard procedure is recommended to remove the brain from the cranium.  The first step is separate the skull cap from the skull bases by sawing circumferentially through the cranial bone, using the frontal tuberosities and occipital protuberance as  Incise the temporal dura mater on both sides without removing it from the inner table  After tilting the head slightly backwards, gently separate the olfactory bulbs from the skull base, then severe the optic nerves, pituitary stalk, and internal carotid arteries at their entry points into the cranial cavity.  While using one hand to dissect, gently support the cerebral hemispheres with the other hand to avoid stretching the midbrain.  Section the tentorium on both sides along the sphenoid bone as far posterior as possible. Identify the vertebral arteries and cut ...

Various treatments and procedures have been proposed for treatment of occipital neuralgia, however, the published literature addressing these treatments consists of small, nonrandomized studies, case reports and case series, as well as retrospective studies and reviews. Gille and colleagues (2004) examined surgical treatment of greater occipital neuralgia by neurolysis of the greater occipital nerve and sectioning of the inferior oblique muscle in a case series study of 10 individuals. Of this group, 3 individuals had anatomic anomalies. The mean follow-up of the series was 37 months. The results of the treatment were assessed according to three criteria: (1) degree of pain on a Visual Analogue Scale (VAS) before surgery, at 3 months, and at last follow-up; (2) consumption of analgesics before surgery and at follow-up; and (3) the degree of satisfaction at follow-up. The mean VAS score was 80/100 before surgery and 20/100 at last follow-up. Consumption of analgesics decreased in all individuals. ...

To examine the impact of occiput posterior position, compared to occiput anterior position, on neonatal outcomes in a setting where delayed pushing is practiced. The specific aim was to estimate the risk of acidaemia. Cohort study from a university hospital in Sweden between 2004 and 2012. Information was collected from a local database of 35,546 births. Umbilical artery sampling was routine. Outcomes were: umbilical artery pH | 7.00 and |7.10 and short-term neonatal morbidity. The association between occiput posterior position and neonatal outcomes was examined using logistic regression analysis, presented as adjusted odds ratio (AOR) with 95% confidence interval (CI). Of 27,648 attempted vaginal births, 1292 (4.7%) had occiput posterior position. Compared with occiput anterior, there was no difference in pH | 7.00 (0.4% vs. 0.5%) but a higher rate of pH | 7.10 in occiput posterior births (3.8 vs. 5.5%). Logistic regression analysis showed no increased risk of pH | 7.10 (AOR 1.28 95% CI 0.93-1.74) when
Maddin et al. present a hypothesis based on the development of skull roof bones in mice and chickens. In mice (and axolotls) the suture between the frontal and parietal corresponds to the boundary between the neural crest and mesoderm in the embryo. In chickens, the latter embryonic boundary is within the frontal itself. Thus the authors suggest the avian frontal is actually a fused frontal and parietal, while the avian parietal is actually a postparietal. They say that hypothesis "is also supported phylogenetically where data from the fossil record reveal separate frontal, parietal, and postparietal bones are present in all stem lineages of extant taxa, including that of birds (e.g., the stem archosaur Euparkeria)." The problem I see is that the postparietal in basal archosauriforms is a tiny wedge between the parietals and supraoccipital, while the parietals have the same topological relationships and morphology in these basal archosauriforms that they do in basal dinosaurs. It seems more ...
Unfortunately, this skull is in one of the hardest primary sedimentary rocks Ive ever seen or hammered upon, and in a block the size of a refridgerator. Theres no way this thing is coming out without access to a jackhammer and a truck. There are four labeled features that help identify it as Herpetocetus. Some of these are not unique to Herpetocetus, but do not occur in any other known contemporaneous mysticetes, so can be used for purposes of identification. 1) The cranial vertex; the vertex is pyramidal in shape, bears a distinct saggital crest on the supraoccipital, which is also very acute. 2) There is a distinct deep fossa medial of the dorsal crest of the squamosal, which is an synapomorphy of the clade Herpetocetinae. 3) The zygomatic process of the squamosal is anteriorly oriented. 4) The postorbital process is elongate and finger like, which may be a reversal to the primitive condition of mysticetes ...
